I have pledged for 4 McModules (+1 Dongle +1 Gateway), and I can’t update the firmware of any of those 4 modules. I used the OTA software as indicated in the instruction video, and the app can’t see the modules. The LED on the Dongle is on and the app says Ready, but I can’t see any light on the modules, even though I tried with 3 different (and charged) batteries. Nothing! All I see is « Connection to device failed » message. I can’t see any LED on any of those.
What should I do? By the way, I’m using a Macbook Retina (with USB-C) with Parallels Desktop and Windows 8.1 Pro on it. It normally don’t cause any problem.
