(Immediate = about 40 milliseconds according to the SerialMonitor timestamps) When issuing AT+CIPSTART=3,"SSL"," ",443 I almost immediately receive 3,CLOSED followed by OK. When issuing AT+CIPSTART=3,"SSL"," I almost immediately receive 3,CONNECT followed by OK.
I have duplicated the problem completely without any Arduino code by typing the commands manually into SerialMonitor with an ESP-01 module plugged into a USB adapter. Even the sample "WebClientSSL" which comes with the WiFiESP library, which works fine for Google, won't work for Īfter much debugging, I have tracked the problem to the establishing of the connection itself. It is simply not possible to connect to. I am therefore trying to use an ESP-01 module and the (excellent!) WiFiEsp library. The custom board doesn't support simply plugging in a shield.
My project is based on a custom "bare-bone" style Arduino and based on an ATMEGA1284.
