Solution applies for these FM devices

FMB900 FMB920 FMB001 FMB010 FM3001 FMB110 FMB120 FMB122 FMB125 FMB130 FMB140 FMB202 FMB204 FMB962 FMB964 FMT100 FMB640 FMM125 FMM130 FMM640 FMC640 FMU125 FMU130 FMC125 FMC130

Pair and connect device

Bluetooth starts automatically when FMB device is on. Take your mobile phone, go to Settings->Bluetooth and turn it on. Scan for nearby devices, find the device in the list, distinguish the device by last IMEI digits on device module. Press pair, wait until the device asks to enter pairing password, type: "5555" (as in the example on the figure). A paired device will show up in the paired device list. Download a terminal for Bluetooth e.g. BlueTerm from Play Store/App Store. Run the app, click Find->Connect to your paired device. Now we need to send a command to FMB from Bluetooth terminal, type: ".log:1"
Device will respond with "Debug enabled" and FMB1YX log will show up. Do not forget to save the log file to the mobile phone.

Device debug over Android smartphone

In order to pair FMB device with Android smartphone, make sure that BT radio is enabled (visible) in device configuration. It can be checked via SMS command too:
"getparam 800"
The answer has to be "2", which means "Enabled and visible".

  • Do a test drive with log running.
  • Type .log:0 to stop log running.
  • At the end click 3 dots (on right) -> Data : Unmark log. The same procedure like before in Step 2, only difference is that you need Unmark log.
  • Find the file and send it to your PC, then attach it in the query.
