Procedure to perform Service Discovery with Softdevice API

[thin_ice]

Hello,

I am using pc-ble-driver to write a desktop application interfacing with Nordic connectivity dongle. There is no automatic discovery module functionality so I have to roll my own service discovery procedure. However I don't think I trusted my procedure 100% so can you please instruct me what your correct way is to start and finish a discovery procedure ?

Given that custom uuid service service discovery is a procedure, and ensure all services and characteristics as well as descriptors must be discovered. Here are the functions I used:

sd_ble_gattc_primary_services_discover()

sd_ble_gattc_relationships_discover()

sd_ble_gattc_characteristics_discover()

sd_ble_gattc_descriptors_discover()

sd_ble_gattc_attr_info_discover()

Thanks !

Hi.

You can follow the different Message Sequence Charts for the GATT Client to make sure that your procedure is correct.

Primary Service Discovery.

Relationship Discovery.

Characteristics Discovery.

Descriptors Discovery.

You can take a look at this example.

Best regards,

Andreas
