Anyone tried to attach a battery to the board while it is connected to computer via usb?
Or can the battery overload the USB port and force the computer to shut down?
Also, I found that:
my U201 board is pegged at SIGNAL=99 (very poor signal) even when it is registered to the network / connected to cloud server.
while in U270 – SIGNAL = 13 to 17 (in the good level) when connected/registered to network.
Could it be that the signal strength is related to power given by computer’s USB port… and is related to frequent connection drop and to the long-wait for connection during bootup.
