Good Day!
I am working on a Remote Start/Stop System for a Generator using a Wemos D1 Mini Pro.
It works great, however occassionally when I press vPin V1 or V9, the board crashes and reboots. I have simplified my code as far as possible and have no idea why it occurs occasitionally.
When I look at the serial monitor, the error decodes to something involving watchdog, I have no idea what that is and read that feeding the watchdog is a fix, but it still happens.
Again this doesnt happen all the time, its just random. This doesnt happen to any of the other vPins such as V10.
Also when i look at the device timeline, the board goes offline and reconnects at random times when I don’t interact with the app, please see attached screenshot.
I am using the latest blynk library (1.01) and my internet connection is stable.
I would really like to make my project as reliable as possible and I look forward for some advice on how to solve this.
Thanks in advance.
