MESH network is as below
：
The figure shows:
1. In addition to receiving its own data, the relay can also transfer data from other nodes. This feature can make the signal
coverage of the network;
2. The operation of the low-power node must require the cooperation of the Fiend role.
Interpret the simulation application scenario above:
The distance from module A to module C is 250 meters, which exceeds the 200-meter transmission distance of our module, so
module A cannot directly send data to module C. If a module B is placed between module A and module C, the data It will be relayed
by B and then received by C.
Module A needs to send data to the entire network, and modules B, C, D, and E need to receive data from A. Then module A can
send data at the broadcast address (0XFFFF).
If the A module needs to specify the data to be sent to the E module, you only need to fill in the address of the E module at the
