Im using a lolin nodemcu v3 board to decode 433mhz signal from a weather station and upload everything on wunderground.
Everytjing work perfectly but only with serial monitor opened
I can't understand why......
The 433mhz receiver send data to d3 pin(gpio0 on esp8266).
If i try to use any other gpio, it doesn't work even with serial monitor opened..the last strange anomaly is that i always see the esp access point if i try to scan for wireless network.....need some.helps
....thank you guys
