Unable to change motor direction after enabling bidirectional DSHOT on F405 AIO

1.Problem  reason

The reason why the motor direction cannot be changed after enabling bidirectional DSHOT on the F405 AIO is that we are using the dshot_bitbang_timer = AUTO command, which is the bidirectional DSHOT command recommended by Betaflight for F405 flight controllers.

Currently, due to an issue with the Betaflight firmware, motor direction cannot be changed within Betaflight when using this bidirectional DSHOT command.

2. Solutions

1. You can change the motor direction using an ESC configurator (such as ESC Configurator - for Bluejay, BLHeli_S and AM32(esc-configurator.com)).
2. Alternatively, you can change the bidirectional DSHOT command to set  dshot_bitbang = AUTO.

How to change it:

Go to the CLI tab in Betaflight and enter the following command:

set dshot_bitbang = AUTO

Then enter: save .  After changing the bidirectional DSHOT command, you will be able to modify motor direction within Betaflight.
