I see that this has been corrected in SDK for Thread and Zigbee 2.0.0.

However, there is another missing case.

in mqttsn_client.c

The function keep_alive_transmission_attempt() calls

mqttsn_client_state_update(p_client, SENT_PINGREQ);

In mqttsn_client_state_update(), the case where fsm_event == SENT_PINGREQ is not handled, so you get an ASSERT with the Debug build.

        case MQTTSN_CLIENT_CONNECTED:
        {
            switch (fsm_event)
            {
                case SENT_SLEEP_REQUEST:
                    p_client->client_state = MQTTSN_CLIENT_WAITING_FOR_SLEEP;
                    break;

                case SENT_DISCONNECT_REQUEST:
                    p_client->client_state = MQTTSN_CLIENT_WAITING_FOR_DISCONNECT;
                    break;

                case TIMEOUT_PINGREQ:
                    p_client->client_state = MQTTSN_CLIENT_DISCONNECTED;
                    break;

                default:
                    ASSERT(false);
                    break;
            }
            break;

Hi Mary,

Thank you for reporting this. I have forwarded the bugreport internally to our Thread team.
