Bluetooth connection problem

[kinderkram]

"Translated" into German:

Es spielt keine Rolle, mit welcher Baudrate der COM-Port im Windows Gerätemanager angelegt ist (der steht defaultmäßig sogar nur auf 9600).

Wichtig ist, dass das jeweilige Gerät auf 115200 eingestellt ist. Wenn Du z.B. vorher eine Gerät mit 57600 benutzt hast (APM o.ä.), dann stimmt die Geschwindigkeit einfach nicht.

Aufgrund der hohen Datenmenge braucht der AQ immer 115200.

Hi Max, Hi Norbert,
thank you very much for your patience!
I understood that the modules themself have to been programmed with the right settings and I did it, but for whatever reasons the air modul of the 433 MHz did not store the settings.
I did flash the modul and did the settings again...WORKING!
Step by step...thanks again for all your help...a great forum and great people...I really appreciate it!

Glad you got it working.
So ... the BT module might be set to anything alse than 115k?

When running into a dead end it´s best to start from scratch and assure all steps have been taken.

Youre right with the dead end...but who cares about bluetooth, when 433 MHz is running nice now

Well, sometimes it is nice to quickly change a parameter by smartphone instead by PC. In such a case, 433 MHz doesn't help

Or simply use both: for quick&dirty jobs the Android App on a BT phone and for serious stuff use a long range telemetry module on a tablet/netbook/notebook. That´s how I use it on my Hexa.
If in doubt about the current drawn you could also pick up 3.3 or 5V elsewhere on the board or UBEC.

Just solder a double row of pins (like the motor pins) instead of the angled ones:
