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 device asks to enter pairing password, type: "5555" (as in the example on the figure). Paired device will show up in the paired device list. Download a terminal for Bluetooth e.g. BlueTerm from Play Store/App store. Run 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 mobile phone.
