After pair&connect request device disconnect

stark

Hi support Team,

I create custom ble-service with help of example project ble_app_att_mtu_throughput (nRF5_SDK_17.0.2)its working successfully.Now i need to add security so i refer the ble_app_gls example and then compiled successfully.

Then,

  • I connect to my device with nRF Connect

The system launches me an explicit PopUp of paring request to my device  i click the pair after that device will be disconnect and message will appear in nRF-Connect  "Couldn't pair with NRF_example(device name in sdk_config.h) because of an incorrect PIN or passkey" but  not appear popup window for me to enter passkey.

Any idea where i'm stuck.

Thanks,

Stark.

    Hi Stark

    Adding bonding to an example that doesn't already have it is quite tricky, since you have to include a lot of different libraries, and ensure they are all configured correctly. 

    Would it be an option to start out with an example that has bonding already (such as the ble_app_hrm example), and then add your custom service to that?

    Best regards

    Thanks for replay,

    Actually in my case amts service suits for me so i need to be add pairing and security.

    Found some error,

    when i call nrf_ble_qwr_conn_handle_assign it will return invalid state i think VERIFY_MODULE_INITIALIZED(); is not initialized .I have called  nrf_ble_qwr_init()  within services_init()  is called before conn_params_init() and  also checked error code from nrf_ble_qwr_init it is returning NRF_SUCCESSFULL

    Can you please let me know how to solve it or reason for the error?

    Hi 

    Are you able to share your main file with me, so I can see how the QWR library is initialized and used?

    I can make the case private if you want, in case you don't want to share your code in a public case. 

    Best regards
