interference to other equipment.
High confidentiality, extremely low probability of interception; strong anti-interference ability, strong suppression of
co-channel interference and various noises; excellent anti-multipath fading performance.
LBT: The module has a Listen before talk (LBT) function. When this function is enabled, the module actively monitors
the channel environment noise before transmitting. If the noise exceeds the threshold, it will be sent delayed. This
feature can greatly improve the communication success rate of the module in harsh environments. This function can
be used for network transmission and anti-collision processing.
RSSI: The signal strength indication function. The module supports packet signal strength serial output. Can be used
to assess signal quality, improve communication networks, and ranging. The module supports ambient noise signal
strength serial output. It can be used to implement LBT functions manually.
Wireless configuration: Remotely configure or read wireless module parameters by sending command packets
wirelessly.
Networking function: The module can implement multi-level repeater networking. Multi-level repeater is suitable for
ultra long-distance communication. Multiple networks in the same area can run simultaneously.
Ultra-low power consumption: the air wake-up function. It is especially suitable for battery-powered applications: when
the module is in WOR state, the configuration module WOR monitors the overall power consumption of the adjustable
module. The maximum configurable response delay of the module is 4000ms. The average current of the module in
this mode is about 2uA.
Fixed-point transmission: supports address function, the host can transmit data to any address, any channel, to
achieve networking, repeater and other application. For example: module A transmits data to module B (address is
