after checking the document, i can confirm that the order and flags of the characteristics (in the service of interest) matches for this prototype OSTC+. Jan, do you remember what procedure we use to verify that second characteristic (00000002-0000-1000-8000-008025000000) has received the READY command: https://github.com/Subsurface-divelog/libdc/blob/e97a47cca55973199715df0f818b4955e60d3a31/src/hw_ostc3.c#L56 i can only find the writing of the INIT command to the first characteristic (00000001-0000-1000-8000-008025000000) in our code base: https://github.com/Subsurface-divelog/subsurface/blob/master/core/qt-ble.cpp#L158 lubomir -- _______________________________________________ subsurface mailing list [email protected] http://lists.subsurface-divelog.org/cgi-bin/mailman/listinfo/subsurface
