    HI,

    1、CC2642 do host to connect CC2642 slave
    2, after a successful connection, the host delay 30 seconds, 30 seconds to the time will take the initiative to disconnect.
    3, after the disconnection, the host reconnects to the slave, and so on.

    When the host requests disconnection in step 2, the CC2642 slave sometimes does not reply. When the slave receives the first disconnect request, it disconnects itself and broadcasts. And the host does not receive a reply from the slave, it will keep retransmitting until the host disconnects after 3 seconds.

    Testing the above method for 1 day will result in this problem 2 to 3 times

    Hi,

    Can you specify if this behavior is reproduceable in an unmodified ble example? If so, then could you share which one? If any modifications are necessary to reproduce, then please share the modifications as well.

    Best Regards,
