ESP8266 Community Forum

- Fri Jul 09, 2021 4:33 am #91843 Hi!
I am using nodemcu with esp8266 basic & creating page works perfectly.

I am sending para from usb to webpage & updating on page.

But when i send data from arduino to rx pin of esp8266 then garbage is receiving.

It seems me rx pin is already connected to usb to serial convertor chip , so data goes incorrect.

can some on have any solution ?

Thanks

• Remap UART0 from GPIO1/3 to GPIO15/13
• Remove R10 (TX) and R12 (RX) from the NodeMCU board (schematic)
• Don't use a board with a built in USB convertor

Assumption is the mother of all f*ckups. At least: that's what I'm assuming.
