1587 Feature: LHT65N will wait for ACK for each uplink, If LHT65N doesn't get ACK from the IoT server, it will consider the message doesn't arrive server and store it. LHT65N keeps sending messages in normal periodically. Once LHT65N gets ACK from a server, it will consider the network is ok and start to send the not-arrive message.
