UdhayaKumar_Mani · January 19, 2024, 7:26am

Hi,

I am using FCM360W Wi-Fi module. I try to connect with TCP and MQTT servers but I was facing some errors like “dns failed” . I was tried both AP and station mode also . But i am not sure what is that problem. I ensured server, hotspot ,internet availability was fine. But that problem came. Please help to resolve this issue .Thanks in advance.
