GatawayESP8266 - Compile error



  • I installed on Windows 7 64bit: Arduino IDE 1.8.15, MySensors lib 2.3.2 and from "ESP8266 by ESP8266 Community" 3.0.0 board: NodeMCU 1.0 (ESP-12E Module). When trying to compile GatawayESP8266 (I only changed to my MY_WIFI_SSID and MY_WIFI_PASSWORD). I'm getting errors and can't compile it 😞

    What am I doing wrong? 😞

    and so on



  • @skom Welcome! You're doing nothing wrong.

    It looks like some changes in the 3.0.0 release of the ESP6266 core that came out a few days ago is breaking most if not all MySensors example sketches for boards included in that package.

    I don't know what is causing this. It seems to be related to the PSTR macro - maybe someone with better understanding of this should have a look at it.

    As a workaround, you can downgrad the ESP8266 core from 3.0.0 to 2.7.4 in the Arduino boards manager and it should compile just fine.



  • Thank you :), version 2.7.4 works 🙂



  • @BearWithBeard Hello !

    I'm new to the forum. I just found out about MySensors today actually.

    I tried making my first gateway, and had the same exact problem as @skom
    A quick search brought me here.
    Looks like downgrading the ESP Board Library to 2.7.4 works fine indeed.

    Thank you sir.
    I love the Internet, and I love you guys. ❤



  • And even in 2022 people are very happy to find this information! Took me about 2 days to figure out what was going on. I did not get any compilation errors and uploading the sketch to the board went fine. However, even the cleanest MySensors sketch did not work on the Wemos D1 mini version 3.0.0. Other sketches like "blink" without Mysensors.h did work.

    Also for me the downgrading to 2.7.4 works. Maybe an idea to put this info on the Mysensors page?

    Thanks again for posting this solution!
