PPK: Initialization failed - could not load calibration values, though they are shown in RTThttps://devzone.nordicsemi.com/f/nordic-q-a/59633/ppk-initialization-failed---could-not-load-calibration-values-though-they-are-shown-in-rttLast time I used it, it worked fine, it&#39;s been sitting in a drawer for some time since then. When I tried to use it now, i get this error - even though I can read the output in RTT.. I&#39;ve tried two different USB cables, one which was new and unuseden-USTelligent Community 13Mon, 30 Mar 2020 19:41:54 GMTRE: PPK: Initialization failed - could not load calibration values, though they are shown in RTThttps://devzone.nordicsemi.com/thread/242550?ContentTypeID=1Mon, 30 Mar 2020 19:41:54 GMT137ad170-7792-4731-bb38-c0d22fbe4515:28339ea2-0aa9-4c0d-a025-1bd5c01c26b3erltot<p>I was using 1.1.0<br /><br />With new nRF connect it didn&#39;t respond at first, I had to clean the firmware and reinstall it but now everything works!
