I assume that the information is stored in a file on the watch. I have an original Multisport watch that doesn't support this, so I can't check it myself. I...

Does the official TomTom software do anything with this data? If so, what?

I see. It looks pretty, but I'm not sure how we should implement this. `ttwatch` doesn't have a GUI, and none of the current output formats support adding this data...

I have added a command line option to switch to a 7-day ephemeris (`-7` or `--eph7days`) and an associated config file option (`Ephemeris7Days = true`). This works for both the...

In my testing, it accepted the file and seemed to work properly. I haven't actually tested it to see if the GPS still locks quickly after more than 3 days,...

Interesting. If you're feeling brave, you could edit `libttwatch/libttwatch.h` and change `TOMTOM_VENDOR_ID` and `TOMTOM_MULTISPORT_PRODUCT_ID` to the values of your Nike watch then recompile and try to use it. If you...

USB endpoints are fairly easy to find. Run `lsusb -v -d11ac` and look at the output. Look for an `Interface Descriptor` with `bInterfaceClass` equal to `3 Human Interface Device`. There...

It looks like it uses different endpoint addresses. I'm not sure if it will work, but you could try. Try replacing lines 225-238 of `libttwatch.cpp` with this: ```packet_size = tx_length...

I don't think I'd be able to do anything useful. I think to make any more progress, you'd need to capture the USB packets transmitted between the watch and the...

I have an older watch which doesn't produce these files, so I'm sorry I can't help. I have no idea what they would be used for. There is nothing in...
