Sending custom data to Teltonika FMC920 via bluetooth

manuemp

First of all, I apologize if this is not the place to ask this kind of specific questions...

Is it possible to send custom data to the FMC920 device via bluetooth? I'm quite new to this type of device, I don't fully understand how it works.

I am trying to send a card number scanned with an RFID reader, from an ESP32 to the FMC920 with bluetooth. From what I read in an official Teltonika PDF, there is no specific command to do this... most of the commands are related to configuration parameters, such as:

:cfg_info:?
.imei
:cfg_setcfg:
etc...

I'm connected to a server that receives information from this device, but always gets the same information (some configuration parameters and GPS), and I'm starting to think that's how it works and there's not much to do.

Is this a server-side issue (maybe everything is being sent and the server isn't showing it)? Or will this device not process custom data no matter what and just wait for default commands?
