Hi Nick,

Thanks for letting us know. Regarding the suggested solution I am not sure using a critical section here is a good idea, as compute_and_give_dhkey() takes a bit of time to complete, and generally spending a long time in critical sections is not recommended (as it blocks any other time critical operations, even with higher interrupt priorities). It could be that it would be better to simply ignore NRF_ERROR_INVALID_STATE in this case, for instance like this:

    err_code = nrf_ble_lesc_request_handler();
    if (err_code != NRF_ERROR_INVALID_STATE)
    {
        APP_ERROR_CHECK(err_code);
    }
