Hi y-zhang_3572401

Apologies for the confusion.! In clear words, nothing will get deleted after recovery. Program and bonding information (BD address) will be there until you reprogram it.

Hi y-zhang_3572401

After recovery of the board,

1. the app downloaded to your board will be deleted

2. BD address of the paired device will also be deleted.

Hi y-zhang_3572401

To be clear, when you recover the board, the board will enter the auto-baud mode, which means the device will think that the flash is corrupted. Whether as when you reset the device after recovery, the device will come out of auto-baud mode, whatever is there in flash will be read and therefore you see the logs of the previous software because you have not overwritten it by programming again.

So exact answer of your question can be, the program does not get deleted but recovery gives you the permission to overwrite it with your new program.

Recover does not delete the software that downloaded to CYBT-343026-EVAL

>BD address of the paired device will also be deleted.

When you program the board, application will be loaded into flash, then gets copied to RAM and from there it executes.

After you do recovery and press reset, the code will again execute from the RAM. So ideally, nothing gets deleted.

Rom is untouched here.
