Before I connected to the Arduino I've wired it up to a USB-TTL cable and wires up the module.
When looking at the output on the COm port I get a boot loop,
All I can see is something about WDT, and then fatal exception (0).
I've read that for the Arduino I need to flash another firmware to get the baud rate to 9600. Currently its 115200
Its not a power supply issue as I have it hooked up to a 3.3V stable PSU.
Any ideas what's causing this or should I just ignore it and flash the latest firmware?
