【提问】:Mqtt <-> RS485 is not working properly
【详情】:Hi I tried to communicate mqtt <-> RS485. RS485 -> mqtt pub is working properly but mqtt sub -> RS485 is not working. Also, once mqtt sub was received, mqtt pub was not working anymore before power reset. Please let me know what should I do? I configured same as ew11 which was working properly. My test environment is like below PC1 USB -- RS485-- HF2211 ---MQTT broker ---PC1 (MQTTFx)
