Introduction of Lora Modem
ZHC0941/0951 supports forwarding data packets of specified modules, which can extend the wireless communication distance limitedly.
One module can forward data packets of multiple modules at the same time, effectively expanding the wireless coverage area.
ZHC0941/0951 supports multi-level relay networking, which can extend communication distance and extend signal coverage to reach blind spots. Support automatic relay networking, which can shorten the engineering cycle.
