Query related to pairing NRF24 Device to HOST using button.

[Nitesh Dubey]

Dear all,

Greetings!!!

I am using the NRF24LE1E module. I want to pair my device with host using a button. Button is available on device side. Please help me to do it. Please share the solution links related to this task.

Hi,

 

If you look at "gzll_device_w_dynamic_pairing" example in nRFgo SDK, these two function calls are what requests the pairing procedure:

      // Send "system address request". Needed for sending any user data to Host.
      gzp_address_req_send();
      
      // Send "Host ID request". Needed for sending encrypted user data to host.
      id_req_status = gzp_id_req_send();
    }

    // If waiting for Host to grant or reject ID request
    if(id_req_status == GZP_ID_RESP_PENDING)
    {
      // Send new ID request for fetching response
      id_req_status = gzp_id_req_send();
    }

 

Note that the above makes use of the encrypted pipe, which is restricted to only one device on the host side. For unencrypted pairing, only call the "gzp_address_req_send()" function (remember to check the return value).

 

Kind regards,

Håkon
