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 ?

Re: A very peculiar problem
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.

Re: [bug] I2c GPS
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

Re: GPS integration
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 ...

[bug] I2c GPS
.. 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

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.
