    FAQ

    • Can it work like a HC-05 module?

      Yes, it is a bluetooth module like HC-05 with Xbee adaptor

    • Inserted it to the Game Pad. Put the switch to AT mode. Tried the AT commands from the wiki and get nothing. What should I do?
      Once you inserted it on Game pad instead of a XBEE adapter, you can only use AT command in code, but it will become useless to use serial monitor sending AT commands.
