Mqtt <-> RS485 is not working properly
Hi
I have trouble to use HF2411.
1. Eventhough HF2411 received data from Serial Port(RS485, RS232..), HF2411 never transfer to SOCK ( MQTT).
- Set up mqtt configure via IOTService app.
2. I made HIS script and upload it to HF244. but SEND() operation was not working. RESET is working fine.
TIMER heartbit 30000
SEND(UART,uart0,"uart test")
RESET
END

Mqtt <-> RS485 is not working properly
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)

是否支持桥接功能
通过两台ew11桥接，连接两台485设备是否可行。若不行，有什么推荐
