439 -LA66 is a LoRa End Node module base on SX1262 core. Use it as relay as mentioned above has below limitation:
440 440  
441 -1. It only supports LoRa radio with fix frequency, fix DR (Spreading Factor) , Fix bandwidth and
442 -1. This method only support uplinks. It doesn;t work for LoRaWAN Downlink.
443 -1. Capacity depends on how often the end nodes sends send uplinks. The LA66 needs to spends around 1~~3 seconds to relay one packet ( depends on DR. inlcudes RX and TX time).
