Thanks for Albert Kim’s share, there is a tutorial on the usage of these two tools:
Q2:How to deal with the problem of flight drift of the aircraft ? A2:Dear customer, you need to calibrate it in betaflight, three ways are possible :
1. Setup Calibrate Accelerometer.
2. Enter " gyro_lpf = 188HZ " in CLI, and then save.
3. Please see Joshua Bardwell Whoop calibration video：
Q3:What kind of remote control can be used in different receiver versions ? A3: Dear customer, the user needs to check the remote control instructions. The instructions will show you whether it supports this receiver mode(such as sbus, ppm, etc) or not, and it will show you how to switch to the receiver's mode.
Q4:How to deal with the abnormal binding?
(Aircraft that binding success but can't use remote control is not included) A4: Dear customer, please refer to the following operation:
1. Measure the voltage between GND and 3V3. If the battery is between 3-5V,
it means that it's not the problem of the flight control power supply.
It might be the problem of the receiver, and the receiver needs to be replaced.
2. If the voltage between GND and 3V3 is below 3V or above 5V, the problem is in the fight control and you need to replace the flight control.
The following is the normal performance of binding:
Q5:After the remote control and receiver is binding successful (receiver light and sound is normal), how to deal with the problem of remote control can't control the aircraft or can't control aircraft after reflash the firmware? A5: Dear customer, in general, it's caused by the incorrect flight control terminal parameter adjustment. You need to adjust it in the corresponding receiver mode of Betaflight. You can refer to the 4 kinds of receivers binding of B06 and BF settings(B06 FAQ Q8-Q13).
