ESP8266 hangs network.
Posted: Sun Mar 06, 2016 1:00 pmHey. I'm using esp8266 as tcp-uart bridge. When I begin transmitting I get network freezing. Try to ping router and get this:
I'm stumped with that. It's not router problem, just tested with torrent and ping time is about 5-10ms.
Transmission function in esp:
