Hi - I am trying to get my Sweep working with a UART connection using the supplied raw cable. I am able to make serial connections using the usb adapter to my raspberry pi, but I want to use the raw serial pins. I eventually plan to connect the sweep to an embedded device that does not have USB and only has UART. I am using firmware 1.4 with a raspberry pi 2.
I have connected the red and black wire to 5V and Ground. The status LED on the sweep is solid blue. I have connected the Blue RX wire connected to TXD (pin 8) and the Green TX wire connected to RXD (pin 10).
ser = serial.Serial(port='/dev/ttyAMA0', baudrate=115200)
The final readline line hangs until I kill it. Any help is appreciated!
