OK. I have my gadget (a CDM 7160), but I seem to be missing the 'basic info' page. There was nothing in the parcel with a clue. I found this website/forum with a bit of duckduckgoing.
Plugging into USB gives me
[710364.564061] usb 4-1: new full-speed USB device number 16 using uhci_hcd
[710364.725618] usb 4-1: New USB device found, idVendor=1a86, idProduct=7523
[710364.725623] usb 4-1: New USB device strings: Mfr=0, Product=2, SerialNumber=0
[710364.725626] usb 4-1: Product: USB2.0-Serial
[710366.251065] usbcore: registered new interface driver ch341
[710366.251095] usbserial: USB Serial support registered for ch341-uart
[710366.251126] ch341 4-1:1.0: ch341-uart converter detected
[710366.263793] usb 4-1: ch341-uart converter now attached to ttyUSB0
And I can connect with screen but I don't know what speed I should be using. Does it say somewhere? At 115200 I see nothing, but no wrong-speed garbage either. Is the protocol documented somewhere?
If I press the button a green LED shows whilst it is held. Still nothing on serial port.
Where is the 'how to use you gadget' page? I did look around the http://vair-monitor.com site and found out about vesprino, but nothing on how to use the vair-monitor. control methods, data out methods, power (does it have a battery, does it need to be USB-powered permanently? - I assume yes), what do the LED colours mean (it was faint purple when I first powered it up).
Clues welcome.
