That actually looks like the Scubapro G2 protocol. Same model of
9-byte command with a 0xC6 command byte and then a 4-byte timestamp
and then 0x10 0x27. From src/scubapro_g2.c:

        // Command template.
        unsigned char command[9] = {0x00,
                        (device->timestamp      ) & 0xFF,
                        (device->timestamp >> 8 ) & 0xFF,
                        (device->timestamp >> 16) & 0xFF,
                        (device->timestamp >> 24) & 0xFF,
                        0x10,
                        0x27,
                        0,
                        0};

        // Data Length.
        command[0] = 0xC6;
        unsigned char answer[4] = {0};
        rc = scubapro_g2_transfer (device, command, sizeof (command),
answer, sizeof (answer));

so you literally *could* try to claim it's a G2 and try to see how far
it downloads.

I think you might want to investigate further - have you looked at the
libdivecomputer source code at all?

There are various minor differences in the details of the Uwatec
protocol, so there might be differences. So maybe it might download
like a G2, but then need parsing as some older Uwatec thing (ie I'd
not be surprised if they just replaced the old nasty IRdA crud with
bluetooth).

See src/scubapro_g2.c for the downloading part, but  notice how it
uses the src/uwatec_smart_parser.c parsing. It might just parse the
same was as the old Uwatec Aladin..
