Dear Support Team,
I would like to ask for help with a problem already reported by others, when the bluetooth connection of the device occasionally is not working, because I have not found a solution to it.
I use the device's bluetooth connection for three functions (not at the same time):
- to configure the device with the Teltonika Configurator
- to connect to a bluetooth headset (for an incoming call)
- to detect a bluetooth beacon (to identify the owner)
When the bluetooth connection is not working, I tried to connect to the FMB device with several devices but it failed. (laptop, tablet, smartphone - I have paired them all before). In most cases, the problem goes away on its own after a few hours (12h<) and I can reconnect to the FMB device and the device detects the BLE beacon again. In some cases, however, the situation did not improve after several days, so only restarting the device solved the problem (SMS Command).
Device: FMB120
Firmware: 03.25.15 Rev:02
Configurator: v.1.5.5.29406
I configured the bluetooth settings of the device based on the information on the Teltonika website:
(Since all three functions work perfectly at some times and not at some times, there is probably no problem with the setting.)
