GATT Queue can not discover all primary services (NRF_BLE_GQ_REQ_SRV_DISCOVERY)

[Bruno Randolf]

I would like to use the GATT queue to discover ALL primary services. When using the SoftDevice calls directly, one would use sd_ble_gattc_primary_services_discover(conn_hdl, 1, NULL) - passing NULL as the UUID will return all primary services.

With the GATT queue and NRF_BLE_GQ_REQ_SRV_DISCOVERY this is not possible - nrf_ble_gq_gattc_srv_discovery_t has a ble_uuid_t srvc_uuid which we can not set to NULL. Later in nrf_ble_gq.c this uuid is passed to sd_ble_gattc_primary_services_discover() so there is no way to get all primary services.

Anything I'm missing? If not please fix in the next SDK version... Thank you.

Hello,

Unfortunately, as you said, the GATT queue module requires you to specify the UUID when doing primary service discovery. I have reported this as a feature request internally.

Best regards,
