I'm using an ESP8266-01S Wi-Fi module on an Arduino UNO.

When I use AT+CIPSEND=4 and then type test it successfully sends that message to my laptop. However, sometimes the module returns a busy s... after typing the message... Then the module board is "frozen" for a couple of seconds to a full minute before accepting other commands.

What's a way to make sure the message gets send without getting that busy s... response. Or how do I catch it and reset the board or something like that?
