Hi Fariz, After flashing your ESP with NodeMCU you erase the AT firmware. So, you can’t send AT commands to interact with your ESP8266. Which tutorial are you following? Thanks
also… When i program it using Arduino it erase all the NodeMcu lua firmware… i try using your tutorial here https://rntlab.com/module-8/controlling-outputs-with-esp-using-mqtt/ at this tutorial i succes connecting nodeMCU to access point, but failed to connect it to my local broker in Raspberry Pi at /home/pi/IOT advais plis
Ok.Rui… After long time searching i got AT firmware original, and now i can use at command again, but when i flash using nodemcu firmware it erase all of at command feature. now it try your tutorial from the course https://rntlab.com/module-8/controlling-outputs-with-esp-using-mqtt/ but i still can t connecting mqtt to my mosquitto which i have installed in raspberry pi… thank
bro Rui… it always come any advaise plis??? https://rntlab.com/module-8/controlling-outputs-with-esp-using-mqtt/ WiFi connected – ESP IP address: 192.168.1.128Attempting MQTT connection…failed, rc=-4 try again in 5 seconds.
Hi Fariz, I’m not sure which tutorials are you talking about…. Throughout the course I never mention or use the NodeMCU firmware, neither the AT firmware… Which tutorial are you following that is causing this misunderstanding? Why do you need the AT firmware at this point?
