Hello @HGhp

The device does support Bluetooth so you can connect device to the Bluetooth module and can try to send message through mobile using Bluetooth terminal application

Please follow the link for more details How to debug FMB device over Android smartphone? - Wiki Knowledge Base | Teltonika GPS

In the FMB920 configuration, Enable Bluetooth and pair the module. Once paired and connected, you can start sending commands and test the communication.

Yes, I have done this
But I want to send other data, for example send the word “Hello” and receive it in FMB920.

Hello @HGhp ,

Actually the device can only respond to commands that are already implemented in its firmware. If you send hello, the device won’t recognize that command and therefore won’t be able to reply.

Please check the commands which you can send to device , FMB SMS/GPRS Commands - Wiki Knowledge Base | Teltonika GPS
