ppk_api's Issues

Average Result is always returned as 0

On running main.py (without any changes) with PPK and DUT connected, the average result is always returned as 0 followed by Nan errors. Below is the output for your reference:

When I connect the same PPK to Power Profiler App in nRF Connect, it's able to measure the current. So, it doesn't look like an issue with the PPK.

PPK2 API

Hi, will you add PPK2 support to this API or you plan to create new API for PPK2?

Update firmware to latest

New firmware has been released, with better voltage regulator control. Update to latest

Segfault on Ubuntu 18.04 x64

Looks like there's an issue in libjlinkarm.so. This segfaults when ppk.measurement_readout_start() is called from main.py

Thread 7 "python3" received signal SIGSEGV, Segmentation fault.
