Clarification on Sending Commands via TCP Using Codec_8 Extended

Telematics
1

We are a software development team, and GPS tracking is one of our main projects. We previously used the HTTP method for tracking devices, but due to some limitations of HTTP, we have now migrated to TCP.

We are following the Codec_8 Extended protocol to develop our device tracking software (Teltonika Codec Documentation).

Currently, we are successfully receiving data from devices via TCP. However, we are facing an issue with sending commands to the devices using TCP. Based on the documentation, we couldn’t find any clear options for command communication through TCP.

From our research in the Teltonika Telematics documentation, it appears that specific protocols are available for sending commands to devices over TCP connections. Codec 8 does not support sending commands from the server to the device, while Codec 12 is the only protocol that enables the transmission of commands over TCP connections.

Could you please confirm if this understanding is correct — that Codec 8 does not support sending commands from the server to the device?

Hello @kiran.sigosoft,

I hope you are doing well. Yes, CODEC 12 Protocol should be used to send commands to the device over TCP connections.

For more information, you may refer on this link: Codec - Teltonika Telematics Wiki

Hope this helps.

Kind regards,
Patrick S.
