[NIDHIN K]

I have two nrf devices nrf51822 and nrf52DK, In nrf51822 i'm using S110 and i had created a custom service with 10 characteristics. If i connected to nrf connect i can able to see all services and characteristics and i can able to send data through this characteristics that means its working fine as expected. So now i want use nrf52dk to discover this custom services and chara and i want send data thorough chara. Pls anybody help me how to discover custom services ans chara  ,give me some examples code ?

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,

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.

Hi,

thank you for your answer.

I'm able to connect with sensors 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.

Please could you explain me how to discover 4 custom characteristics at 128bits?

Thank you in advance.
