Question

Hi,

my client just send me one FMB125, and asked me to analize it and do some testing on it. The thing is that i need to send some commands to the device, but i'm a little bit lost regarding that.

we have the c# tcp listener that was shared by teltonika, now i have 2 questions.

i need to get the imei from the device, or is there any easier way to identify every device? (device id? or something like that?)

the other question is regarding the command that i need to send to the device, i'm trying the following.

once i got the call from the device i try to write on the same stream with the following.

var ReplyBytesCmd = new byte[] { 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x0F, 0x0C, 0x01, 0x05, 0x00, 0x00, 0x00, 0x07, 0x67, 0x65, 0x74, 0x69, 0x6E, 0x66, 0x6F, 0x01, 0x00, 0x00, 0x43, 0x12 }; // this is supposed to be the getver command

var decodedData = DecodeTcpPacket(fullPacket.ToArray());

await stream.WriteAsync(ReplyBytesCmd, 0, ReplyBytesCmd.Length);

i'm sure i just missunderstood something.

thanks for any guidance.

Hello,

Thank you for your query.

Every time device sends its IMEI to server, server should respond (ACK) 01 or 00 if this is correct IMEI for further communication.

If you want simply send GPRS command via hercules.exe just paste hex code and send it. Device should respond with the answer.

getver command in Hexadecimal: 00000000000000100C0105000000086765747665720D0A0100004D36

Please follow codec 12 protocol on our wiki page: https://wiki.teltonika.lt/view/Codec#Codec_for_communication_over_GPRS_messages

Hope this will help. Regards,

Teltonika Support.
