How do you send csv file via bluetooth?

Right, in trouble from the start :grin: You can't send a whole file at once, so it would have to be sent row-by-row.

A Bluetooth data packet has 20 bytes for the payload. The title row "Date, Time, Name, cell, unlv, lov, unlc, loc, res." is approx 50 bytes.

Do you have some sample data rows?
