If multiple groups of data transmission stations are used for one-to-one communication in the same area, it is recommended
that the channel interval of each group of data transmission stations be set at least 2MHz.

Note: The higher the air speed, the faster the transmission rate, the closer the transmission distance; Therefore, in the case that the
speed meets the requirements of use, the lower the airspeed is recommended.

Note: It is recommended to retain more than 50% current margin when selecting the power supply, which is conducive to the
long-term stable work of the station.

Automatically send 58 bytes per package
Note: 1. If the data received by the station is larger than the capacity of a single packet, the excess data will be automatically
allocated to the second transmission until the transmission is completed;
2. The data received by the radio at one time shall not be larger than the cache capacity;
6. Operating mode
E32-DTU has four operating modes. When there is no harsh and low power demand, it is recommended to configure the station in the
general mode (mode 0) for normal communication.The radio is set to general mode (mode 0) by default when it comes out of the
