Destination

Msg_TripLoad

Allocate a trip message buffer and return its buffer handle. This needs to be included in every new trip/destination to be sent to CoPilot. This defines the options for how a trip is to be added. Trip messages have a variable number of stops. The DLL must allocate memory to store these stops in a trip message and pass the message to CoPilot. This function stores the main portion of a Trip message structure for subsequent calls to and Msg_SendTrip .

Use Msg_ParserDelete to free the memory when finished with ParserID.

Syntax (Prototyped in alkmsg.h)

long Msg_TripLoad(long actionCode,
    long tripID = 0,
    long lMsgID = Msg_ID_Trip);

Parameters

Notes

• To clear the trip, set actionCode = Msg_ACTION_REPLACE without adding any stops (i.e. do not call Msg_TripAddStop).

• To disable the confirmation dialog on the CoPilot Application, set the actionCode parameter to the bitwise-OR of the desired action and Msg_ACTOPT_NOCONFIRM.

• To optimize the stops in CoPilot’s trip itinerary, set the actionCode parameter to the bitwise-OR of the desired action and Msg_ACTOPT_OPTIMIZE OR Msg_ACTOPT_OPTIMIZE_DESTFIXED.

• When GPS feed is provided, CoPilot will remove the first stop in the list.

Return Value

• Less than 0 = Failed

• Greater than or equal to 0 - Successful

Returned ID needed for subsequent calls to Msg_TripAddStopWithHouseNum and Msg_SendTrip .

Adding Single Stop

You need to use Msg_TripLoad trip, followed by a Msg_TripAddStopWithHouseNum followed by a Msg_SendTrip() in the same order with appropriate arguments.

Adding Multiple Stops

You need to use a Msg_TripLoad trip, followed by a multiple Msg_TripAddStopWithHouseNum (depending number of stops) followed by a Msg_SendTrip() in the same order with appropriate arguments.

The recommended code sequence for multiple stops:

lngTrip = Msg.Msg_TripLoad(Msg.MSG_ACTION_REPLACE | Msg.MSG_ACTOPT_NOCONFIRM | MSG_ACTOPT_OPTIMIZE_DESTFIXED, 0, Msg.MSG_ID_Trip);

for (int i = 0; i < addresses.Length; i++)
{
var address = addresses[i];
Log.Verbose(LogCategory.Copilot, "Address(" + (i + 1) + "): " + address);

lngTest = Msg.Msg_TripAddStopWithHouseNum(
(int)lngTrip,
CopilotUtil.ConvertString(i.ToString()),
CopilotUtil.ConvertString(address.street),
CopilotUtil.ConvertString(address.streetName),
CopilotUtil.ConvertString(address.city),
CopilotUtil.ConvertString(address.state),
CopilotUtil.ConvertString(address.zip),
null,
address.lat,
address.longt,
Msg.MSG_ID_TripNew, null, null, null, 1);

if (lngTest <= 0)

{ Msg.Msg_SendWindowMode(Msg.WM_SH_HIDE, -1); throw new Exception("Trip add stop failed"); }
}

Msg.Msg_SendTrip((int)lngTrip, -1, -1, Msg.MSG_ID_TripNew);

Msg_TripAddStopWithHouseNum

Add a stop to a previously allocated trip message buffer, all individual stops need to be added. To be used when House number and Street Address need to be defined separately.

Syntax (Prototyped in alkmsg.h)

long Msg_TripAddStopWithHouseNum (long ID,
                        char *pName,
                        char *pHouseNum,
                        char *pAddress,
                        char *pCity,
                        char *pState,
                        char *pPostal,
                        char *pJurisdiction,
                        long lLat,
                        long lLon,
                        long lMsgID = Msg_ID_Trip,
                        char *pNorthing = NULL,
                        char *pEasting = NULL,
                        char *pGridSQ = NULL,
                        long lStopVia = 1);

Parameters

Return Value

• ≤ 0 - Failed
• Greater than 0 - Successful

Additional Notes

Latitude and Longitude Input All Latitude and Longitude values are sent as long integers. These values are encoded as millionths of a degree. North and East are positive values, South and West are negative values. For example, ALK London office is located at 0.122805W & 51.518220N so it should be passed as a -122805 longitude & 51518220 latitude.

ID and one of the following combination parameters are mandatory. 1. lLat and lLong 2. pState and (pCity OR pPostal) 3. pNorthing, pEasting and pGridSq

Logic when only sending in Lat/Long for address: When using a Latitude and Longitude only, the location does not exactly snap to a road, which can lead CoPilot to take the most convenient road to the route (not the nearest), which can cause issues in the routing. In order to overcome this issue, we would recommend that you add one of the following adjustments: Within User.cfg please add the following line:

> [Geocoding] <br>
> "CleanupBestChoiceOnly"=1 <br>

Other Option for either:

• If you pass street address with the lat/long, we try to match the address details if this is within a short distance of the Lat/Long provided, we will snap the location to the correct road.

Postcode search results:

• When entering postcode information and searching streets you may notice a number of results are returned for streets that do not match the postcode entered. These are stated as being within the neighboring area. This means that they do not match the exact postcode entered but they are nearby in case you have incorrect details.

To remove these addresses from the list of return destinations please add the following entry to user.cfg .

[Geocoding]
“DeleteOutOfCityMatches”=1

Address vs Coordinates vs Address and Coordinates What if I have a Latitude and Longitude value as well as the street address, what is the priority in CoPilot?

• Scenario 1 – Only the full address is passed via SDK • This is straight forward CoPilot will try to geocode the address.

• Scenario 2 – Only Lat is passed via SDK • This is straight forward. CoPilot will try to use lat-long to provide the route.

• Scenario 3 – Both Address and Lat-Lon are passed via SDK • If CoPilot receives a complete lat/long and address details

  • CoPilot will assume the lat/long is 100% correct
  • CoPilot will identify all nearby street names and search each one by distance to match the street name provided in the input address. CoPilot will snap to the closest link, regardless of house number.
  • In the address field CoPilot will mask the house number to match the version supplied, even if it is not the nearest house number to the Lat/Lon provided
  • If no matching street name can be found within 1 mile, CoPilot will use the lat/long.

Msg_SendTrip

Send a new trip itinerary (list of stops) to the application. This is used following Msg_TripLoad and Msg_TripAddStopWithHouseNum

Sends a message with trip stop to destination ID.

Syntax (Prototyped in alkmsg.h)

long Msg_SendTrip(long ID,
                  long lDestID = CONN_ID_NONE,
                  long lSrcID = CONN_ID_NONE,
                  long lMsgID = Msg_ID_Trip);

Parameters

Return Value

• ≤ 0 - Failed
• Greater than 0 - Successful

Notes

• CoPilot will send the acknowledgement by Msg_ID_GeocodeResultSet , if user does set the Msg_ACTOPT_RETMULTIMATCH during Msg_TripLoad .

• CoPilot will send the acknowledgement by Msg_ID_GenericData (payload Msg_IDT_GEORESULT), if user does not set the Msg_ACTOPT_RETMULTIMATCH during Msg_TripLoad . For CoPilot 920 and above, we highly recommend customer to use Msg_IDT_GEOCODE. Msg_IDT_GEOCODE contains more information including any geocoding error, latitude, longitude, stop name, place errors and address errors.

• Version 920 CoPilot and above

  • CoPilot will respond with a geocode result to Msg_ID_GenericInformation (identifier Msg_IDT_GEOCODE). For further information, please read the Msg_ID_GenericInformation in detail.

Msg_TripParse

This is the first API to be used if you wish to receive all the details of the currently loaded Trip. Decodes and retrieves the message ID from a trip message buffer.

Syntax (Prototyped in alkmsg.h)

long Msg_TripParse(void *pBytes,
   unsigned long bytes,
   long lMsgID = Msg_ID_Trip);

Parameters

Return Value

Returned ID needed for subsequent calls to Msg_TripGet and Msg_TripGetStopInfo .

Msg_SendTripJSON

This API is used to send stops in JSON format from the client application to CoPilot. This will include the stop location, side of street tolerance, stop icon as well as advanced ETA attributes.

If the user would NOT like to change views MSG_IDT_CURRENT_VIEW should be passed to CoPilot.

Syntax (Prototyped in alkmsg.h)

long Msg_SendTripJSON(long actionCode,long lShowGUIIdentifier, bool bShowCoPilot,
const char* pJson);

alkmsg.cs
  public static extern int Msg_SendTripJSON(int actionCode, int lIdentifier, bool bShow, byte[] pJson);

Parameters

lShowGUIIdentifier Identifiers

This is the second step to be used if you want to receive details of the currently loaded Trip. This provides header information including the total number stops

Syntax (Prototyped in alkmsg.h)

long Msg_TripGet(long ID,
   long &rActionCode,
   long &rTripID,
   long &rStopCount,
   long &rSourceID,
   long &rDestID,
   char *pFromScreenName,
   unsigned long maxFromScreenName,
   long lMsgID = Msg_ID_Trip);

Parameters

Return Value

• ≤ 0 - Failed

• Greater than 0 - Successful

Msg_TripGetStopInfo

Used in conjunction with Msg_Trip* APIs, returns itinerary stop list information from a Msg_ID_Trip message, returning all individual stop details. We recommend using Msg_tripGetStopWaypointInfo instead of Msg_TripGetStopInfo.

Syntax (Prototyped in alkmsg.h)

long Msg_TripGetStopInfo(long ID,
   long index,
   char *pName,
   long lNameLen,
   char *pCity,
   long lCityLen,
   char *pState,
   long lStateLen,
   char *pAddress,
   long lAddressLen,
   char *pZip,
   long lZipLen,

   long &rLatitude,
   long &rLongitude,
   long lMsgID = Msg_ID_Trip);

Parameters

Return Value

• ≤ 0 - Failed

• Greater than 0 - Successful

Notes: The first stop returned by Msg_TripGetStopInfo() is the current location of the vehicle and the rest are the stops present in CoPilot’s itinerary.

All Latitude and Longitude values are sent as long integers. These values are encoded as millionths of a degree. North and East are positive values, South and West are negative values. For example, the Trimble Maps London office is located at 0.122805W & 51.518220N so it should be pass as a -122805 longitude & 51518220 latitude.

Msg_TripGetStopWaypointInfo

Used in conjunction with Msg_Trip* APIs, returns itinerary stop list information from a Msg_ID_Trip message, returning all individual stop details including Waypoints. We recommend using Msg_tripGetStopWaypointInfo instead of Msg_TripGetStopInfo

Parameters

Return Value

• ≤ 0 - Failed

• Greater than 0 - Successful

Note: The first stop returned by Msg_TripGetStopInfo() is the current location of the vehicle and the rest are the stops present in CoPilot’s itinerary.

Note: All Latitude and Longitude values are sent as long integers. These values are encoded as millionths of a degree. North and East are positive values, South and West are negative values. For example, the Trimble Maps London office is located at 0.122805W & 51.518220N so it should be pass as a -122805 longitude & 51518220 latitude.

Msg_SendTripStopInfoRequest

Sends the request to CoPilot to get the list of stops in CoPilot’s itinerary, to be followed by Msg_TripGet* APIs. We recommend using Msg_SendStopInfoRequest instead of Msg_SendTripStopInfoRequest

Syntax (Prototyped in alkmsg.h)

long Msg_SendTripStopInfoRequest(void);

Notes

In order to retrieve the list of stops in CoPilot’s itinerary, you must have previously set a callback for the Msg_ID_Trip message. This is done as follows. First, declare the callback:

void OnTripMsg(const char *pBuf, const unsigned long lBufLen){
  // Declare all variables to be used in this function here
  long msgID = Msg_TripParse(pBuffer, cBuffer,MSG_ID_Trip);

  Msg_TripGet(msgID, actionCode, tripID, lStopCount,
  lSourceID, destID, fromScreenName,
  sizeof(fromScreenName), MSG_ID_Trip);

  for (int i = 0; i <lStopCount; i++)
  {
    long ret = Msg_TripGetStopInfo(msgID, i, stopName, sizeof(stopName),
      cityName, sizeof (cityName),
      stateName, sizeof (stateName),
      address, sizeof (address),
      zipCode, sizeof (zipCode),
      jurisName, sizeof (jurisName),
      lLatitude, lLongitude,
      MSG_ID_Trip);
  }
  // Use the data in your application here
}

Second, set the callback for Msg_ID_TripNew message via the SDK:

Msg_UpdateOptions(Msg_ID_Trip, true, true, false, (void *) OnTripMsg));

Finally, call Msg_SendTripStopInfoRequest() to request the position immediately:

Msg_SendTripStopInfoRequest();

Return Value

• ≤ 0 Failed

• Greater than 0 Successful

Msg_SendStopInfoRequest

Sends the request to CoPilot to get the list of stops in CoPilot’s itinerary, to be followed by Msg_Trip* APIs, includes information on Waypoints. We recommend to use Msg_SendStopInfoRequest instead of Msg_SendTripStopInfoRequest

Syntax (Prototyped in alkmsg.h)

long Msg_SendStopInfoRequest(void);

Parameters

None

Notes: In order to retrieve the list of stops in CoPilot’s itinerary, you must have previously set a callback for the Msg_ID_TripNew message. This is done as follows:

First, declare the callback:

void OnTripMsg(const char *pBuf, const unsigned long lBquen) {
  //Declare all variables to be used in this function here
  long msgID = Msg_TripParse(pBuffer, cBuffer, MSG_ID_TripNew);

  Msg_TripGet(msgID, actionCode, tripID, lStopCount, lSourceID, destID,
    fromScreenName, sizeof(fromScreenName), MSG_ID_TripNew);
  for (int i = 0; i < lStopCount; i++) {
    long ret = Msg_TripGetStopWaypointInfo(msgID, i,
      stopName, sizeof(stopName),
      cityName, sizeof(cityName),
      stateName, sizeof(stateName),
      address, sizeof(address),
      zipCode, sizeof(zipCode),
      jurisName, sizeof(jurisName),
      lLatitude, lLongitude,
      lStopVia, HSG_ID_TripNew);
  }
  // Use the data in your application here
}

Second, set the callback for Msg_ID_TripNew message via the SDK:

Msg_UpdateOptions(MSG_ID_TripNew, true, false, (void *)OnTripMsg);

Finally, call Msg_SendTripStopInfoRequest() to request the position:

Msg_SendTripStopInfoRequest();

Return Value

• ≤ 0 - Failed

• Greater than 0 - Successful

Msg_SendStopInfoRequestJSON()

Sends the request to CoPilot to get the list of stops in CoPilot’s itinerary in JSON format.

Syntax (Prototyped in alkmsg.h)

long Msg_SendStopInfoRequestJSON(void);

Parameters

None

Return Values

{
InitializeComponent();
delOnSDKStopInfoResponseCB = new Msg.delSDKDeliverCB(OnSDKStopInfoResponse);
 }

private int OnSDKStopInfoResponse(IntPtr pData, uint numBytes);
{ String sJson = Msg.MarshalNativeUTF8ToManagedString(pData); }

//Second, set the callback attached to the “TSdkStopInfoJsonRsp” flex callback message via the SDK:
        Msg.Msg_SetFlexCallback(Util.ConvertString("TSdkStopInfoJsonRsp"), delOnSDKStopInfoResponseCB);

//Finally, call Msg_SendTripStopInfoRequestJSON() to request the position:
                    Msg.Msg_SendStopInfoRequestJSON();

//The JSON representation of the itineraries stops will be received in the callback function.

Msg_DrawImageAtCoordinates

Use this API call to dynamically add an Image Drawer category into CoPilot. This will draw a specified image at the lat/lons provided in the call. Please note the category provided will be created in isolation from any POI category that may be present on the device. For example, if you named a category ‘Fuel’, this Image Drawer Category would be completely independent from the POI category of the same name, ‘Fuel’. It is recommended that any Image Drawer Category should be given a different name from any of the POI categories present on the device.

Syntax (Prototyped in alkmsg.h)

long Msg_DrawImageAtCoordinates(char* pLatLong, char* pCategoryName, char* pImageName, bool bOverwrite)

Parameter

• true Overwrite the existing category with the new one.
  
• false Do not overwrite the existing category.|

Note: The ID field is optional and lat/lon pairs without the ID are supported. For example, “42629813,-76179562” is still a valid value for pLatLong.

Return Value

• -1 or less than 0 = Error
• Greater than 0 Successful in sending the request to CoPilot.

Notes

1. When using this API CoPilot will respond with a result using the MSG_ID_GenericInformation callback with identifier MSG_IDT_IMAGE_DRAWER . For further information, please read the documentation for MSG_ID_GenericInformation in detail.
2. All latitude and longitude values are sent as long integers. These values are encoded as millionths of a degree. North and East are positive values, South and West are negative values. For example, the Trimble Maps London office is located at 0.122805W & 51.518220N so the longitude value should be passed as -122805 and the latitude value should be passed as 51518220.
3. The images that are drawn on the maps are slightly different to those used for POIs. As such, the user can not click on the image to get information and drive to that location, neither can they search for an image like the can when searching for a POI.
4. The image file should be placed inside \skin\user folder so the API will be able to integrate the image.
5. Images that are drawn on the maps are removed on CoPilot exit. So user needs to call this API again if CoPilot is relaunched.
6. CoPilot displays 24-bit 44x44 icons correctly, but if they are of different size, CoPilot will size the icon appropriately to fit. If the images are too large, CoPilot will not display images properly.

Msg_DeleteAllCategory

This API can be used to delete all of the user defined Image Drawer categories that have been added into CoPilot.

Syntax (Prototyped in alkmsg.h)

long Msg_DeleteAllCategory()

Return Value -1 or less than 0 = Error. Greater than 0 = Successful in sending the request to CoPilot.

Note: When using this API CoPilot will respond with a result using the MSG_ID_GenericInformation callback with identifier MSG_IDT_IMAGE_DRAWER. For further information, please read the documentation for MSG_ID_GenericInformation in detail.
