I made some changes to my app to allow it to send data to Google Sheets and I have somehow lost BLE connectivity. The app "sees" the BLE device in the list picker and, once I connect to it, I am told my UUIDs are messed up (at least that is how I read it) but I do not see any problems.
I am including screen shots from my blocks and the error message and it just doesn't make sense (to me,). If anyone has an idea, please tell me.
After I read your response, but before I threw a hissy-fit, I grabbed screenshots from NRL Connect and the truth was made clear. I had inexplicably changed the last3 digits of my Service URL . . . go figure! Thank you for your logical advice!
