Pin Description:
Explanation:
-
When the module is powered on, the green and blue lights are on. When the bluetooth / USB flash drive / TF card is connected, the blue light will flash and show that it is working.
-
The module is powered on that shows green. If the blue light flashes, the default is the bluetooth mode, the mobile phone or car open bluetooth, the search module bluetooth account “bluetooth”, the connection is successful and the disconnected account will have voice prompts, then the priority bluetooth selection.
-
When accessing USB flash drive or TF card, USB flash drive and TF card will be preferred at this time, and there will be a prompt tone;
- The alternating blue and green flashes indicate that the device is being searched for; the blue steady flashing indicates that bluetooth is connected.
