Built-in TX/RX automatic switching circuit, TX/RX status can be switched independently without external control signal.2. It works in RX status by default, and enhances the receiving signal. When the transmitting signal of the superior device is detected, the module instantly switches to the TX status.3. The TX gain is adjustable, which is convenient to be compatible with wireless devices with different transmission powers.4. Compatible with various modulation methods such as LORA and FSK/ASK/OOK/MSK/GFSK.Tips:The output power of the upper-level device must be at least 3dB higher than the switching threshold, which means that the output power of the upper-level device cannot be lower than 1dBm, otherwise itmay cause unstable operation.
