swap the yaw and pitch imput with inputs known to work one your board .. it will help determining the connection issue .

is this for a standard pulse width transmitter or a sbus one ?

kos

are you in level mode ? looks like your quad just want to level ..

add props and hold firmly the quad .. then by adding a little throttle , you will see what the motor want to do

do not exptect too much from bluetooth .. so little range , so little power and so much noise , it is not reliable.

hum ... if your statement is true , then I should find a line of code checking for i2c_errors_count or an equivalent block. but there is no such line in the code .

mwc will not arm because of waitTransmissionI2C() , but this is a side effect and not an expected behaviour , we should no rely on bug

you have I2C errors ! your I2C link with the I2C GPS is not working. One reason is perhaps your I2C speed. If it's not 400Hz you need to change the speed in the file twi.h to #ifndef TWI_FREQ #define TWI_FREQ 100000L #endif and GGA, GSA, VTG ...?? Aclosed someone has of you as a circuit diagram of ...

.. if no i2c gps is connected or if the i2c gps get disconnect : mwc stop working .

step to reproduce :

- enable i2c gps with define
- disconnect your i2c gps or turn it off or do not connect anything to the i2c bus
- start mwc
- mwc will not arm

make some datafusion of the estimated position, velocity and error of the INS and the GNSS, if not done already. In other words, when the GNSS position jumps but the INS doesn't recognize any movement in X and Y, why should it move to the newer position if the actual error is small? Kind regards, w...

A high proportional gain results in a large change in the output for a given change in the error... for a multicopter , this is a large change of rpm.

And because "nous le valons bien" the quad is build with original nintendo parts, like a real multiwii
