Have you checked out this Central tutorial ?

(it is based on an older SDK, but should be applicable for your environment as well.)

If you look at tutorial and use the UART central example as reference, you will have a great starting point.

Hi,

Please could you help me?
Did you add custom service UUID at 128bits with custom characteristics at 128bits?

Thank you in advance

Hi,

thank you for your answer.

I'm working on "central side" and I'm able to connect to my sensor but when I receive the event BLE_DB_DISCOVERY_COMPLETE, I don't read the uuid of the 4 custom characteristics but I read characteristic.uuid.uuid = 0x00 and characteristic.uuid.type = 0x00.

This, I think because I use the function sd_ble_uuid_vs_add only for the custom service.

I need to understand how to configure the 4 UUID at 128bits of characteristics for the central.

Thank you in advance.
