#85905 Hello everyone. I am new to this community and IOT itself.
I have my own arduino UNO, esp8266 board and arduino ide with esp libraries installed in it.

While connecting esp8266 to arduino with selecting Board as Generic ESP8266 Module it gives me an error ->

### Debug Messages

Please suggest me what to do next as i am stuck with this error from last 3 days.

  • What kind of ESP8266 module?
  • What kind of UNO, one with a DIP chip or with an SMD chip (with the first you can just remove the IC with the latter you have to force the IC in reset)?
  • How did you connect the ESP8266 to the UNO (do you have a schematic or a website you took the info from)?
  • What sequence are you performing to put the ESP8266 in programming mode?
Whatever the answers, a friendly word of advice from me: buy a development board for $2 - $3 like the NodeMCU or a Wemos. :idea:

#88748 Hi, I also have this issue.

I am using the Wemos D1 Mini. I have installed the ESP8266 2.7.4 boards to the Arduino software.

Following this tutorial:
http://www.esp8266learning.com/max30102 ... sp8266.php

I have a working max30102 sensor, but it is coming up with the same error. I have changed the board version that I used multiple times and it comes up with different errors. This error for the 2.7.4, with the 2.5.0 it states that the esp8266 is out of sync. So I'm not sure what to do.

Link to the code I'm using:
