We are travelling with our show. esp8266 chips talking to wifi router without internet connection. Works great at home, but when we take it to a stadium we get interference from all of the electronics from the crowd. The calls to the chips are timing out.
Any ideas on how to combat the issue? I see a ESP32-C5 chip that is 5ghz version. Our other idea to not use WLED app w/ wifi and and use push buttons for effects.
The other simple thing to try is pick a channel not heavily used at your location.
2.4Ghz systems typically default to channel 6 which often gets hammered by random devices.
Also consider using something other than the “192.168.x.x” subnets such as 10.76.69.68.x to keep things isolated.
You might also try setting your Wifi router to a hidden SSID and/or if possible set the router to ignore MAC addresses not in it’s Whitelist.
If you’re looking to drop WiFi completely, you could also try some of the hardwired ethernet devices (if you can live with ethernet cables).
