4.2. Wireless part
4.2.1. Basic Wireless Parameters
Channel: The devices that need to communicate should work on the same channel, and the current working
frequency band can be calculated according to the channel value;
Working frequency = lowest frequency band + channel value * channel spacing
Module address: Transparent transmission should ensure that the addresses of the devices that need to be
communicated are the same, and the configuration range is 0 to 65535;
Airspeed: Ensure that the airspeeds of the devices that need to communicate are the same, and only take effect in
"fixed-length transmission", and "continuous transmission" airspeed adaptation does not require user configuration;
4.2.2. Work mode
General mode:
The radio station receives the user data from the wireless, and can also send the data through the wireless, and the
sent data is automatically divided into 58 bytes for transmission.
Wake Mode:
The radio will automatically add a wake-up code before each data packet, and the length of the wake-up code
depends on the wake-up time set in the user parameters;
