Am I right you only tested downloading over bluetooth (BLE)? Can you 
also try over USB? I suspect that logtrak still does the handshaking 
when downloading over USB. If that's correct, then omitting the 
handshaking is not specific to the Sport Matrix, but the underlying 

Note that logtrak also supports a second variant of the handshaking 
(0xF4), in case the other two (0x1B and 0x1C) return zero, but I have 
never seen that so far. Maybe the Sport Matrix is in this category?

I believe you have the model number wrong. I think it should be 0x17, 
and your test seems to confirm that:

Command: 0110
Output : 0117

Do you mind sending me a libdivecomputer memory dump and logfile?
