ESP8266 Nodemcu getting stuck
Posted: Fri Sep 24, 2021 1:06 amHi, I have a setup with 3 i2c sensors and 2 analog sensors(via analog mux) connected to a ESP8266. I am powering everything using a DC power supply of +5V. I managed to get the sensor readings for few mins and after that the esp8266 is getting stuck until I unpowered and powered back the esp8266. and then again working for sometime. I am not using any pull-up resistors. Please help me with this issue. The code is below
Code: Select all
//#include "TRIGGER_WIFI.h" /*Includes ESP8266WiFi.h and WiFiClientSecure.h, just have these two libraries downloaded before*/
//#include "TRIGGER_GOOGLESHEETS.h" /*Library file for Google Sheets, has to be used after Wi-Fi Client Secure declaration, here everything is in Trigger_WIFI.h, so using it after Trigger_WIFI.h*/
