El dispositivo FMB120 no envía datos de canbus, si envío un sms con el comando " lvcansetprog 12921" me devuelve: LVCAN ProgNum: 12347

Por qué no cambia el num de programa? que estoy haciendo mal?


The FMB120 device does not send canbus data, if I send an SMS with the command "lvcansetprog 12921" it returns: LVCAN ProgNum: 12347

Why doesn't the program number change? what am I doing wrong?

Hi have you tried to put 2 space before the command?   lvcansetprog X

or if you set your user name and pwd it should be like this format   login pass lvcansetprog X

Have you tried to delete all records in flash storage , then try to reboot your device after you reboot your device try to send the same command, if does not work using sms command i will recommend to use the configurator to set the program number. (2) Teltonika CAN adapters Part 2: Installation - YouTube

1. make sure that your device has the latest firmware
