#11253 Hello everyone ...

MY ESP-01 gets really really hot when the wifi connection to the router is lost .... Is it normal ?

#11407 Could it be that one of the GPIO pins goes HIGH when the connection is lost?

It might be connected to a common ground and shorts out when the pin goes HIGH.

#13488 Hi,
I have the same with my two ESP8266-03. They got hot very quickly. All GPIO's have pullup of 10k.
At the first one WIFI is no more possible.
At the second one TxD seems destroyed.
Anyone an idea?
Kurt
