• Send and receive message remotely with ESP8266

  The result is that the WiFiSecureClient doesn't work when used in the bot declaration, so I changed the variable to WiFiClient but I can't use the certificate, so I comment it out and ESP8266.h gives me a thousand errors due to lack of dependencies in its libraries. I should point out that I downloaded the entire project from the Arduino ESP8266, I don't know how to link all the libraries, so I simply took those from the ESP8266WiFi.

• Do you have any idea why this program would not work? [ESP32]

• How do you determine what module/s do you have on your boards or vice versa?

• Programming esp32

  He meant the Arduino framework. There is an Arduino core for the ESP8266 so you can use Arduino’s IDE and libraries for the ESP with this core here

• rst cause:2, boot mode:(3,6) ERROR :(

• Help Needed: ESP NOW between ESP Wroom 32 DevKit and WeMos D1 Mini.
  1 project | /r/esp8266 | 11 Mar 2023

  According to this link(https://github.com/esp8266/Arduino/issues/6174) WeMos can't receive broadcasts on SDK 2.2.1.

• ESP8266 on ESPNow protocol power consumption/sleep mode
  1 project | /r/esp8266 | 9 Mar 2023

  There are 2 ways to minimize power consumption while maintaining an active WiFi connection, but it's not a large power reduction for either mode. Look at Automatic Modem Sleep and Automatic Light Sleep here: https://github.com/esp8266/Arduino/tree/master/libraries/esp8266/examples/LowPowerDemo

• lolin boards in close proximity are causing WIFI interferance
  1 project | /r/esp8266 | 26 Feb 2023

  That's the Arduino (Uno) library. If you've correctly installed the ESP8266 package then it should be 3.(something-ish) for the ESP8266 version of the WiFi library. Current is 3.1.1 for the core files, and the WiFi is part of the core libraries. If you have your compile options set for verbose then you should see it doesn't access that old Arduino WiFi library.

• Is there any way to get a low battery alert from a D1 mini?
  1 project | /r/esp8266 | 20 Feb 2023

  Seems it's expected https://github.com/esp8266/Arduino/issues/721
