CONFIG_BT_GATT_AUTO_SEC_REQ

Automatic security re-establishment request as a peripheral

Type: bool

Help

This option requests security re-establishment automatically whenever
a reconnection to a GATT client is established and
there are notifiable or indicatable characteristics for which security
is required. This configuration option only applies to the peripheral
role, which sends a Security Request for this purpose.
When disabled, it is the application's responsibility to call
bt_conn_set_security() to re-establish security prior to sending any
notifications or indications on the characteristics that require
security (unless the central does that first).
This option has been introduced to avoid interoperability issues with
commercially available central devices that react negatively to
receiving a Security Request immediately after reconnection.
