This seems to work if you use the Nordic development board not the Rigado BMD-300

Ok, the message "Initialization failed, could not read calibration values." comes from an exception (line 1091 in ppk.py), so you will have to print the exception message to get more information about the issue that is causing this.

Nope, same result.

Ok, I have only seen this error occur when the PPK is accidentally flashed with the application meant for the nRF5-DK(PPK mounted on the DK when you flash the application or softdevice.). Could you try to flash the PPK with the flash_ppk.py script, and then run the ppk.py right after that.

1. python.exe flash_ppk.py
2. python.exe ppk.py

Windows 7 on a VM on OS X. Others in the group have exactly the same issue on W7 running on a DELL laptop. link text

What operating system are you running on the computer?

I just re-flashed it and I got this when I stated up PPK. (HOW DO YOU ENTER PREFORMATTED CODE - Tried the icon and typed

 and neither worked)

Make sure that the PPK is flashed with the correct firmware. Try to flash the PPK again with ppk_v1_0_0.hex.
