Irrelevant WiFiClient disconnected by ESPhttpUpdate.update
Posted: Sun Jan 29, 2023 1:43 amHi!
I was testing OTA with NodeMCU and espClient was disconnected by ESPhttpUpdate.update as you can see this sketch:
Did I miss anything or this is normal?
How should I keep espClient CONNECTED while ESPhttpUpdate.update working?
Thanks,
Yinglu

Did I miss anything or this is normal?
How should I keep espClient CONNECTED while ESPhttpUpdate.update working?
