Zahid,
Also, which UART pins should I connect my external device to? The documentation I looked up confused me a bit since there a couple of different UART connections taking place. Do I connect my external device to the application UART pins at the front of the Ez device (where the power pins of the battery board connect), the BT UART pins labeled JS on the Ez device itself, or to the UART uEVM pins located on the back of the Ez device?
