I am trying to send some data from STM32 nucleo board to esp8266 wifi module through RX and TX pins. this data will be send to cloud then. But the data is not reaching esp8266 module. I am using arduino ide to program STM32 board. What can I do ?
wire RX to TX and do not forget to wire ground
Yes, I did the same connected
rx------tx
tx------rx
gnd----gnd
but still didn't work When I checked the serial monitor of both stm32 flashed code and nodemcu flashed code.
STM32 serial monitor:- nodemcu serial monitor:-
data sent to nodemcu was shown nodemcu got connected to wifi but no data was
shown thereafter, nothing was received
I am trying but not finding anything relevant to my problem.
and what application runs in the esp8266?
I am using arduino ide to program esp8266 and want to send the data received by nodemcu to cloud. So basically I want to send the data from stm32 to nodemcu somehow rest all the things will be sorted.
