I'm relatively new to the mbed architecture and rpc, so please excuse my ignorance. I've managed to communicate with my MAXREFDES100 using BLE, but RPC seems to offer finer control, so I wanted to attempt it.

I've connected the MAXREFDES100 to the programming chip MAX32620 and then to my computer. The chip powers on just fine, and executing:

gnu screen connection

screen /dev/ttyACM0 9600

I get the initialization prompt which matches the one from the firmware code. However, I was unable to issue commands via screen. I found the RPC tutorial and followed it with python. I power cycled the chip and opened a python prompt:

pyserial connection

import serial
ser = serial.Serial('/dev/ttyACM0',9600)

again, I get the initialization sequence. However the following hangs at the readline stage:

pyserial i/o


it is similarly unresponsive if I to control the LED via:

led control
