I just paired my Peanut Plugs today and noticed that I wasn't getting power values, but saw on the forums that it might require upgraded PP firmware to do so. Using the 3S touch screen, I went to the "Connected Sensors" screen, chose one of my PPs, tapped the "Advanced" button, then "Check for updates". A new firmware was found and I proceeded to upgrade, but it results in a "Upgrade Failed" message. Tried multiple times, with multiple PPs (within a foot of the S3), unpaired/repaired, etc. I also confirmed that my S3 firmware is up to date. What am I missing?
