877 +=== 3.2.10  Auto Send None-ACK messages ===
878 +
879 +
880 +TrackerD will wait for ACK for each uplink, If TrackerD doesn't get ACK from the IoT server, it will consider the message doesn't arrive server and store it. TrackerD keeps sending messages in normal periodically. Once TrackerD gets ACK from a server, it will consider the network is ok and start to send the not-arrive message.

902 +BLEMASK is to filter the unwanted BLE iBeacons during scan. For example, if BLEMASK is 123456. LBT1 will only uplink UUID info which includes 123456. It will ignore all other iBeacons which doesn’t contact 123456 in the UUID.
