I recommend you to look at the "ble_app_uart_c" example and look into the "nus service" "ble_nus_c.c" file so you can see how its handled there.

You can use the sd_ble_gattc_write() function to send data.

In the discovery (ble_nus_c_on_db_disc_evt) you save the handle in the characteristic and then use that handle in sd_ble_gattc_write().

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.

Hi,

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

Thank you in advance

Thanks Martin.

Now I have created discovery function and I can able to see the services and it's characteristics. But I can't able to send data through specific uuid characteristics ,

Hi,

I'm using nRF52832, SDK_14.2.0, s132.

I'm working side "multilink central" and I already have a working sensor to connect with.

The custom sensor profile consist of 1 custom service at128bits and "4 custom characteristics at 128bits". Each characteristic has different uuid at 128bits even from custom service uuid at 128bit.

Please can you just explain me how to discover custom service and it's custom characteristics?
Thank you in advance.

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.
