CUSTOM UUID DISCOVERY

[Mehrdad]

Hi all,

Is there any example to discover the custom UUID services with pc-ble-driver c/c++? As far as I understood, the ble_db_discovery is not supported for this driver.

The issue is sd_ble_gattc_primary_services_discover() only accept the ble_uuid_t and I cannot pass ble_uuid128_t to discover the services. 

Thank you in advance for the tips.

Hi Mehrdad

I of course meant ble_gatt_db.h file, so if you didn't see past my typo please use that header file. If it isn't supported you should have a look at how the BLE_GATT_DB_MAX_CHARS is implemented, to see how exactly it changes the maximum characteristics discoverable.

Best regards,

Simon

Thanks a lot for the following up. I solved the problem and I had to write the service discovery myself since all the characteristics are not discovered at once.

Hi Mehrdad,

May i know how did you managed to find the custom uuid? I managed to find a few which are 16 bits but i am unable to find those with 128 bits.

Your help is greatly appreciated.

Hi, 

Yes, I did. I can quickly let you know what I did. only one question, are you using pc-ble-driver?

1. First, defined vendor specific uuid and the service

2. Second, added this service to BLE stack and then started service discovery

Hope can be helpful.
