Central Address Resolution characteristic

[Mario Amigot]

Hi there!

According to the Bluetooth specification (Version 5.2, Vol 3, Part C, 12 GAP service and characteristics for GATT server) the 'Central Address Resolution' characteristic (0x2AA6) is optional for the a Peripheral device:

However, even using the SoftDevice S113 (which only implements the Peripheral role), the 'Central Address Resolution' characteristic is still present under the 'Generic Access' service in the GATT data base.

How can I make the SoftDevice S113 not to include the optional 'Central Address Resolution' characteristic? [I'm using nRF52840PDK (PCA10056 v0.9.0), nRF5 SDK v17.0.2, S113 v7.2.0]

Thanks in advance,

Mario

Ok, I found the solution:

Including this code:

ble_cfg_t ble_cfg;

ble_cfg.gap_cfg.car_include_cfg.include_cfg = BLE_GAP_CHAR_INCL_CONFIG_EXCLUDE_WITHOUT_SPACE;

sd_ble_cfg_set(BLE_GAP_CFG_CAR_INCL_CONFIG, &ble_cfg, ram_start);

before calling:

sd_ble_enable(&ram_start);

CAR characteristic does not appear under Generic Access anymore.
