I managed to tweak the code a bit so it would spit out the relevant data which I captured on the pc. However when using the phone app the latest firmware update has been pushed to the meter I believe. I have tried using the latest example that you provided and that dosn’t work at all. It exits at didn’t find our friend.
Has this code been tested and is there any additional files required.
Is it possible to revert back to the previous firmware version where I had a system working????
