Hello,

1. I am not quite sure what changes you have done here, but make sure you check the return value of all esb api() calls. I suspect some of the calls are returning error codes here.

2. Also, you can find in the datasheet of the nRF54L10 the default register values of the radio and other peripherals if you are uncertain of what they should be by default.

3. Also to compare the hardware configuration you can do the following:

Read out all registers for the following situations to compare

3.1 Boot -> Type1

3.2 Boot -> Type2

3.3 Boot -> Type1 -> Type2

3.4 Boot -> Type2 -> Type1

You can read out by running: python .\read_global_registers.py --all

To store the output to a file call: python .\read_global_registers.py --all > file1.txt

devzone.nordicsemi.com/.../nrf54l10_5F00_application.zip

Then you can for instance compare 3.2 vs. 3.3 and 3.1 vs. 3.4.

After TYPE2 pairing fails, the ESB configuration remains identical to the configuration when TYPE2 pairing succeeds exclude DATAWHITE.
The ESB configuration is as follows，and is same to the define value:
