Description
HT-M00 is a low-cost dual-channel gateway.It is located to smart family LoRa applications that work with less than 30PCS LoRa nodes. This gateway is based on two SX1276 chips driven by ESP32. We wrote a software mixer (also called a baseband simulation program) to make it possible to achieve 125KHz SF7~SF12 spreading factor monitoring.
