Key overwrite feature allows to overwrite old pairing key records when key storage is full and a new pairing request occurs, or new keys are distributed. If enabled when key storage is full and a keys storage slot is requested, the oldest keys added will be removed. So new devices can be paired with no limitations and no need to determine, which devices should be unpaired to free key storage space explicitly in application. To enable the feature set CONFIG_BT_KEYS_OVERWRITE_OLDEST=y. Oldest keys are determined by minimum value of up-counting aging counter. If you set CONFIG_BT_KEYS_SAVE_AGING_COUNTER_ON_PAIRING=y aging counter values will be updated each time the secure connection is established. This might increase flash wear out if at least two secure connections are established and shut down periodically. When the option disabled aging counter is still updated on each new secure connection, but not stored to flash. Signed-off-by: Sergiy Nikolayenko <sergiy_nikolayenko@jabil.com> |
