Is there any news on this subject?
I've got 4 X M5stickC units, with 3 being "dead on arrival"
Plugging them into my laptop brings them to life, but only 1 stays on when the usb power is removed.
I loaded this example script to get the Battery & supply voltages
The good one shows about 4v from the battery and 4.99v on the usb power.
The other three show
I've tried the G0 to GND trick, but that didn't work.
I did go looking for a new firmware, as mentioned above, but the link is dead.
Any help would be most welcomed.
