I need to put a BT module, but I have only the small HC-06 that needs 3.3V and now I don´t have that voltage onboard since I´m using the BLDC- Joerg expansion board.
It has a 5V in the BT connector, but I tested with the several modules I have and most of them doesn´t work. Only one (LINVOR, I guess flyduino) shows the HUD moving but not other data transfer (no Waypoints, no parameters, etc).
Anyone knows a module that works on M4 using the BLDC expansion board of Joerg?
Thanks
