Question

Hi,

I am trying to send commands to a FMB640, however the commands are not accepted by the device. I receive regular avl data without problems. This is what I do:

1) receive registration of device (using TCP)

2) confirm with 0x1

3) receive data of device (codec 8)

4) confirm with 0x000000yy where yy is the number of records

5) wait for 0.5sec, then send command to device using codec 14

I do not receive a response. This is the command I send:

00000000000000160e01050000000e359632108633367867657476657201000036ad

The log file says:

I am surprised by the line

[2020.01.23 15:01:28]-[D.P.TCP]-> CODEC12 not supported CODECID 14

Is this the error message triggered by my command? Can you point me to the right direction?

Thanks!

Hello,

Thank you for your query.

I believe you already have FMB640 protocol document how device communicates with the server. I have to mention that FMB640 firmware does not support Codec14. This was added only to the FMB units (light trackers) from firmware version FMB.Ver.03.25.04.Rev.00,

There is a description of all Codecs: https://wiki.teltonika.lt/view/Codec#Codec_for_communication_over_GPRS_messages

Best Regards,

Thanks, codec 12 works fine with the FMB640.
