[Arduino demo source code for KC868-A4]-11 how to create wifi connection

[masoos]

if you are using KC868-A4 , actually you not need to use "download" button, it can auto download. just make sure your have stable dc12v for the board.

Hello,

I still encounter the problem, that the board is only recognozed by my USB when I hold the reset button. when I release reset, I hear windows sound and the USB disconnects. I searched for this problem and I found that other encountered similar problems with other boards. https://forum.arduino.cc/t/arduinos-only...sed/305602....

I think this has something to do with the RTS signal. There I see a difference with or without reset

Any idea how I can fix this?

I have latest USB drivers
The board shows a stable 5V and 3,3V signal on the oscilloscope.

Thanks, 
M
