0x00 01, channel is 0x80), date is AA BB CC, the communication format is: 00 01 80 AA BB CC, where 00 01 is the
module B address and 80 is the module B channel, then module B can receive the AA BB CC (other modules do not
receive data).
Broadcast monitoring: Set the module address to 0xFFFF, which can monitor the data transmission of the module on
the same channel; the transmitted data can be received by the module of any address on the same channel, thus
playing the role of broadcasting and monitoring.
Forward error correction: The module has FEC forward error correction algorithm, which has high coding efficiency
and strong error correction capability. In the case of sudden interference, it can actively correct the interfered data
packets, greatly improving reliability and transmission distance. When without FEC, such packets can only be
discarded.
Deep sleep function: When the module is in sleep mode, mode 3, the wireless receiver is turned off and the
micro-controller is in a sleep state; at this time, the power consumption of the whole device is about 2uA.
Watchdog: The module has a built-in watchdog and performs precise time layout. Once an exception occurs, the
module will restart within 1 second and continue to work according to the previous parameter settings.
Parameter saving: After the user sets the parameters, the module parameters will be saved, the power will not be lost,
and the module will work according to the set parameters after power-on.
Applicable environment: 900MHz is free frequency band, users can use it directly without application; 900MHz
features certain penetration and diffraction ability, suitable for environment with small data volume, long transmission
distance and easy to be interfered.
