I’m quite new to Arduino world, but have some confidence and I’m trying to make a domotic project for my house using many Arduino IDE compatible devices and nRF24l01.
So when I discovered this Xiao I bought 3 and was very enthusiastic about it, so much so that last week I bought another 3 (am I wrong or has the price gone up a bit?).
After that, within a very short time, 2 of these Xiao stopped working altogether.
The first one when I was trying to do a sketch upload (modifying just a constant, before was working), and the second one when I unplugged the Xiao from the PC to connect it to a USB wall adaptor.
Both have the same behaviour, green light on but totally passive I/O, and connecting them to the PC (Win10 Pro x64) they are not recognized at all and it doesn’t even emit the classic sound of when a device is connected.
I’ve tried looking on this forum, there seems to be a reliability issue, some have managed to restart the controller with a reset, or double reset or changing the pc USB port, but none of these methods worked for me.
I found in the forum also a solution using a raspberry, but unfortunately I don’t have one, I have instead an Arduino Uno and an Arduino Nano, is there any other way to “revive” those Xiao with the elements I have available?
Losing 2 Xiao out of 6 after only one month would be very disappointing for me because it would mean that I can’t even rely on the remaining ones for projects to be permanently installed in the house…
