IV. Data Communication
4.1 Transparent Data
When the module is in transmission mode, wireless data transmission can be received
through the module serial port.

4.1.2 Data data transmission characteristics
After sending a channel data with a serial port under [Transtransmission mode], the
transmission and receiving channel of the module will be temporarily changed to the
channel, and the module will be restored to the channel configured under [Configuration
mode] after power off or restart.
The serial port cache size of the module is 260 bytes. If the serial port sends more than 260
bytes of data to the module, the first 3 bytes will cycle over the data domain data
automatically since the first 3 bytes are the target address and channel.
The module currently supports a maximum of 255 bytes of data communication, of which
248 bytes are valid data. If the valid data sent to the module exceeds 248 bytes, only the
valid data of the first 248 bytes will be kept and sent externally.
