Adafruit ESP8266 unreachable after desktop wakes from sleep
Posted: Tue Apr 27, 2021 10:27 amI'm trying to make a thermostat and I'm using Adafruit's ESP8266. I wrote a program to control relays over wifi, but when using my desktop computer, after it wakes from sleep or starts up, it will no longer be able to reach and control the board.
Resetting the board will fix it and it'll work again, but every time, putting my computer to sleep and waking up will cause it to stop being able to be controlled. When this happens, I've checked on other computers and they are still able control the board. Desktop is connected to the network via ethernet.
This also happened with my Samsung Galaxy S21 Ultra. I can't get it to happen consistently, but my phone will also sometimes stop being able to reach the board.
Same again with my laptop. Waking or starting up my laptop while the board is running, I can't control it. Resetting the board will get it to work. Also happens consistently. Laptop is connected to network over wifi.
My original program uses the BasicOTA example which I've modified, however, this happens even with a basic program that only connects to wifi and does nothing else.
