Hellp people,
I own 3 FMB920 and I can connect to them with Teltonika Configurator via Bluetooth ONLY on 2 of them.
I'm sure I've set correct bluetooth PIN to the third, but now I can't connect to it anymore.
I can send commands via SMS and via web, but I can't find a way to RESET to "5555" (default bluetooth PIN) the device.
What can I do?
Can someone help me, please?
