I've installed the arduino IDE, added the ESP board manger URL in preferences and added the ESP8266 in the boards manager.
I have three esp01 devices, one is marked ESP01S on the board the other two I'm not sure of the memory details, I have two USB uart dongles, one has a program/uart slide switch, the other has not switch but a really large cap.
Compiling and uploading both seem to work fine.
I'm trying to get any of the Generic ESP8266 examples operational.
I've tried the BlinkwithoutDelay but the LED does not blink.
It seems that any example that includes serial functions produces fatal exception messages on the serial port.
Not sure what feature function or thing I've not set correctly.
