my experience with these modules ....
1> You only get about 2/3 of signal level[compared to generic -12E] , removing switch under antenna will give a little more.
2> The usb/rs232 seems to function well, I used 1 to support a 1-wire sniffer.
3> All 10 units I have seem to function properly, except for poor signal level.

I just tried flashing my WiFi Witty using the simple Arudino blink scrip using the NodeMCU v1 board profile.

However, I see that there is always an open unsecured "ESP_81xx" WiFi connection when the board is on.


Is that part of the original Gizwits firmware? Shouldn't the new arduino firmware remove all previous firmware?

playing around with this witty board, yes, also experienced what you encountered on rgb led... take note that it is an ordinary rgb, not a WSxxxx series ... can be played around since it is connected individually...

I've received this board:

I'm new with this board, and I can not run a simple program of turning on and off of the LED, with the IDE.
Someone managed? Can I get help?

Thanks.
