Powering up Simblee by other power source (failed)
« on: March 09, 2017, 09:21:42 PM »
Hello all,

I have tried to power up the simblee board by other power sources instead of the rfduino usb shield. I connect the simblee boards with different scenarios (with different power sources), and i found out there are some problems.

I have attached a full picture of all scenarios (Attachment A). Not working means i cannot upload any program nor read the data from the sensor. It shows UART TIMEOUT FAIL...FAIL...FAIL...

Any help is greatly appreciated.

Thanks!

You need to connect GND between the boards.
