Pair and connect device

Bluetooth starts automatically when 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. "Serial Bluetooth Terminal", from Play Store/App store. Run app, click Find->Connect to your paired device. Now we need to send a command to the device from Bluetooth terminal, type: ".log:1"

Device will respond with "Log enabled" and the log will show up. Do not forget to save the log file to mobile phone.

Unfortunately, it is not possible to perform debug the same way on iPhone, because there is no native SPP Bluetooth profile support on iPhone.
