GPRS Command syntax for CalAmp

JulesKenneth

Can anyone tell me the correct command syntax to use with flespi Toolbox in order to request a GPS position update from a CalAmp GPS device? I know that CalAmp Report Type 8 is a GPS Location Report. I know that I can send and SMS to CalAmp using syntax !R3,1,255 and that will cause CalAmp to repond with position update (and an event code 255) to whatever server is programmed into the CalAmp device. I also know that if I am connected to CalAmp serial port, I can use send AT$APP GPS? and it will obtain GPS update. But I would like to know what to send over the GPRS channel. I think all commands sent to CalAmp devices ove a GPRS channel should be in Hex.

Whatever I tried so far returns "NAK (not a supported operation)" in Toolbox. I am trying to send the commands via Ruhavik. It should be noted that if I send a position request to CalAmp devices using Wialon, I get the proper response. But I don't know exactly WHAT Wialon is sending.

Any help would be appreciated.

Hello Jules,

You can also send the AT command "AT$APP GPS?" via gprs channel using "AT" command. According to the current syntax is the commands looks like: "$APP GPS?".
Also you can use "Custom command" which we recently added. To do this, you need to select command type 7 and send the following HEX code 0A00000000000000. This command fully corresponds to the one sent by Wialon via the GPRS channel to request the position of the tracker.
The platform substitutes the header itself, you need to fill the date after sequence number.
