At ITTSB Europe,
since 2015, I did engage testing and evaluating Bluetooth hardware performance.
Long range Bluetooth connections this is a major goal, for any one interested for Data Logging due all sort of capable measuring instruments.
Long range Bluetooth connection this warrants that your logging session this will not be trashed, due issues relative to specific radio band and technology / hardware limits.
Bluetooth supporting hardware (radios) of 2015, this getting old and it gets replaced due many reasons.
All relative topics, 2015 ~ 2026, they have now
a dedicated Board, all in one place.
