What files do I have to delete from the device to get it working again? I deleted every file with date on it but it still says "please sync".

I would like to use only this software to get it working because I only have linux and I don't want it to connect to Internet. My computer should be enough.

I have a Polar A360, Firmware v1.2.60, HW-Model 00756861.01

We want to use a polar A360 in our hospital. And as you can imaging we are not happy (and allowed to) to send de data of our patients into the Polar cloud. So I was very happy to find your software. I installed the software onto a windows system en was able to connect en read/dump the files from the connected device. I nerver used python before so as far I can understand you use the protocol buffers to decode the files when they are read from the device but how can I convert the files into a readable format ( e.g text ) so we can use then in excel ? Regards Bart Nienhuis

...and how can it looks like?!?

Maybe display a example udev rule, if the current user can't access, as here #8

Maybe something like this:

SUBSYSTEMS=="usb", ATTRS{idVendor}=="0da4", ATTRS{idProduct}=="0008", OWNER="<username>"

Fill ids and username automaticlly. (I don't test this rule and don't know if it`s a good idea and a common rule...)

I have m400 connected to usb and when trying to list devices using loophole I get this:

I'm using ubuntu 16.04 with kernel 4.4

I am really interested in accessing detailed sleep and heart rate data. What types of data can be downloaded with this library? Is there any sample data available for a demo?

The "dump" will save many files, but it will not end and "hang"...

Strg-C will raise this:

  File "src/loophole/loophole/__main__.py", line 185, in do_dump
    data = self.device.read_file('{}{}'.format(directory, file.name))

    timeout)

    timeout)
KeyboardInterrupt

Maybe the default timeout=2000 is a little bit to long?!?

EDIT: I not see that the last file is: /SYS/FONT/JA.SIF (3135521 bytes) maybe it needs more time, because it`s a big file?!? Is it possible to display some status information?!?

I am trying to diagnose a Windows permission problem using pyusb.

It shows up with the typical errors "The device has no langid (permission issue, no string descriptors supported or device error)" and "The device has no langid (permission issue, no string descriptors supported or device error)"

Test code is simple, just find and print the dev to see if strings have been fetched and try to do a set configuration.

This works correctly on Linux and several of my Windows test systems (both Windows 10 and 11.)

But it is failing consistently on one Windows 10 system.

The device in question is a Garmin Ant+ (aka Dynastream) dongle. It can be accessed by other software correctly on that system. I have tried several different ones, as well as a Cycplus Ant+ dongle. None can be accessed.

I have also tried running the test program from a command prompt started as system administrator. No differences.

I am testing this with a pyinstaller created exe that bundles in the libusb-1.0.dll, and verified that works correctly on my other Windows systems.

Also tried libusb0.dll. Again works correctly elsewhere, but fails on the one Windows 10 system in an identical fashion

Suggestions would be welcome!

Thanks!

Polar A360 Activity Tracker works fine - connect, list, dump, get, walk. 'list' issues a "[!] Failed to get extended info.", but that does not seem to be a problem, Manufacturer, Product name, Vendor ID, Product ID and Serial number are shown properly.

Dear @rsc-dev, I get the following error message when I try to connect loophole to my Polar Vantage V:

.../__init__.py", line 502, in open assert self.ep_out_0 is not None

I realize the Vantage series was not out when you wrote the code, but would you be so kind as to look into this matter, or perhaps give me some pointers so that I can try myself?

Many thanks in advance.

Hi!

I'm trying to use your software with Polar v650. The list command does see the device, but when I try to connect it I get an error

loophole(no device)>list 0 - Polar V650 (BUEY4HDMAIMVW8OJ)

Is it possible to solve?

Thanks!

Hi Roscoe, I'm wondering if you're still doing any work on this. I bought a polar ignite model, and unfortunately loophole doesn't seem to want to connect. If you have any thoughts on what I might try, I'd appreciate it very, very much.
