I tried to send examples commands to my Codec 8 Extended TFT100 but it does not answer.
Try to use the next commands:
getinfo - 00000000000000110C010500000009676574696E666F0D0A010000DA7E
getio - 000000000000000F0C010500000007676574696F0D0A0100003349
Do you agree that I can send GPRS Codec12 messages to a Codec8 Extended device?
Protocols Codec 8 Extended and Codec 12 for different purposes:
Codec8 - transmission of information about location, sensor values, IO elements and other things.
Codec8 – a main FM device protocol that is used for sending data to server.
Codec 12 - interaction with the server via GPRS commands.
Codec12 is original and main Teltonika protocol for device-server communication over GPRS messages. Codec12 GPRS commands can be used for sending configuration, debug, digital outputs control commands or other (special purpose command on special firmware versions).
Also, do you have a program / software on Windows that parse messages? I'd like to test if I parse the messages correctly.
Yes, we have a special program for it. You should make query for your sales manager or helpdesk system.
