Hi clemet,

Using sdk 5.20 tool 11.1 using mutirole project,

Their is a pairing problem , when connected with third party BLE applications like "LightBlue, Blescanner, NRFconnect " pairing popup is appearing and able to pair,

,but we created own application for connecting the devices at that time popup is not enabling from the mobile (GATT is connecting(All services are working )) .

 this is the configuration for IO capabilities.

    Hi,

    Thank you for reaching out.

    Based on the SysConfig configuration shared, it seems the CC2642 device is configured to wait for a pairing request from the phone. I guess your application is not sending such pairing request (either on purpose or by accessing a GATT characteristic requiring pairing), which leads to the behavior described.

    In order to change this behavior, I would suggest to implement one of these two elements:

    1- Configure the CC2642 to initiate the pairing request by setting pairing mode to "Initiate a pairing request"

    2- Configure your mobile app to initiate pairing or access a GATT characteristic requiring pairing

    I hope this will help,

    Best regards,

    Hi,

    Great progress!

    It now feels like two parts of the system may actually require different types of pairing. The second pairing seems to be requested by a part of the system requiring Authentication.

    I hope this will help,

    Great! Well done!

    I guess this is because the CC2642R device initiates the pairing process. If you want the communication over an unauthenticated, unencrypted link to be possible, then you should consider changing. Otherwise, I am afraid you absolutely have to wait for the end of the paring process.

    For the pairing issues mentioned, I would recommend opening a new thread where you list down the phones models and OS versions leading to pairing issues. To get faster assistance, I recommend reproducing the pairing issues with the unmodified multirole or simple_peripheral example and the SimpleLink Connect mobile application. https://www.ti.com/tool/SIMPLELINK-CONNECT-SW-MOBILE-APP
    If available please provide Bluetooth sniffer traces showing the issue.

    I hope this will help,

    Best regards,
