BLE bonding limit

[kevinlam]

Hello,

Below thread described 15 bonded devices can be stored in ESP32 and it will delete the oldest bonded device to make room for the new one when the device reaches the limit.

Is there a way to change the max number of bonded devices? Also, can change the rules that ESP32 WILL NOT delete the oldest bonded device but just report "bonded devices full" message during bonding?

Thanks,
Kevin

For question 1: you can change the size of the macro BTM_SEC_MAX_DEV_RECORDS.

For question 2: Different users may expect different behaviors, you can change the behavior of _btc_storage_save function.

Has this changed the last 3 years or do you still have to make changes in the idf to be able to deny bonding instead of deleting oldest?
