【提问】:Mqtt <-> RS485 is not working properly
【详情】: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
