How to clear the bonding data every time you make a connection

Hello, Dialog.

This time, we are developing software based on ble_app_all_in_one.
When pairing, I think that saving the bonding data to FLASH and not sending the advertisement packet.
I'd like to send the advertisement packet again after disconnecting.
Can you teach us an effective method of not saving bonding data or clearing bonding data?

Hi sogababe,

Hi sogababe,

Please give me more information about:

1) What kind of advertising do you want to make after the connection (for example non connectable)?

2) How do you check that the system is blocked when the flash is erased?

BR,

STS_Dialog.

Thank you for your reply.

Thank you for your reply.

I'm sorry, I realized that I do not have to store the bonding data in FLASH.
It is in user_config.h
#定义USER_CFG_APP_BOND_DB_USE_SPI_FLASH
If you invalidate it, it is recognition that bonding data will not be saved in FLASH.
In my program, because I am using a secondary boot loader, I was thinking to use 0x1E000 ~ 0x1EFFF on FLASH memory map as user data storage area.
However, in app_bond_db.h, when USER_CFG_APP_BOND_DB_USE_SPI_FLASH is valid,
#define APP_BOND_DB_DATA_OFFSET (0x1E000)
Since this line becomes effective, it seems that offsets will collide.
I believe that this triggered my program to cause unstable behavior.
It seems that it can be solved by invalidating storage in FLASH.

Thank you very much.
