在使用以上所说的频率时，服务器有时会调节节点的速率，因为节点默认是开启

When using the frequency mentioned above, the server sometimes adjusts the rate of the node, because the node defaults to the adaptive rate. When the server adjusts your node rate to 0, the maximum payload length is 11 bytes. The server sometimes sends an ADR packet to the node, and the node will reply to the server after receiving the ADR packet, but the number of payload bytes exceeds the limit, so a normal uplink packet will be sent, and then an additional 00 data packet will be sent.
