[BUG] 920xt not mounting automatically about workoutizer

[gotiniens]

Sorry I was unclear, the pmount command works on the RaspberryPi after installing the package.

I will try to write implementation.

[fgebhart]

So from what I can see the following is happening:

1. You connect your device via USB
2. udev detects the connected device and calls the systemd wkz_mount.service
3. the systemd service in turn triggers the workoutizer api endpoint mount-device
4. workoutizer fails to mount the device

At least the first three steps are successful. The system recognizes the connected device, which is a good thing.

Unfortunately I don't have a 920XT laying around 😉 so I'm not able to reproduce this. But one thing that directly pops to my mind is that I'm able to configure the "USB Mode" of my watch. When navigating to Settings > System > USB Mode I am able to select either "MTB (Media Transfer)" or "Garmin". Setting this to "MTP (Media Transfer)" allows workoutizer to successfully mount the device. Could you have a look if there is a similar option on your device?

[gotiniens]

Yes only the last part is failing, I used the API call during debugging to initiate the mount, because the raspberry was not near me.

I understand you don't own every Garmin device available, We can not all be DCRainmaker. I do also have an 910xt which is a future project, because it uses only ANT for fit file transfer. But i'm willing to help the project as much as I can, so I can troubleshoot/research this issue.

Unfortunately my device does not have the "USB Mode" setting

Can you send the output of the following commands, when your device is connected?:

gio mount --list --detail
gio mount -d /dev/bus/usb/{BUS}/{DEV}
udevadm info --name=/dev/bus/usb/{BUS}/{DEV} --query=property
cat /proc/partitions

[fgebhart]

Sure, find the output of the commands when my device is connected below.

Have you tried connecting your watch to your ubuntu machine? I learned that ubuntu does a great job in terms of auto-mounting my device. Could be helpful to compare the two setups and settings.

Having connected my FR645 on my RPI 3B:

Let me know if there is anything else I can support you with while debugging this! If you should find another possibility of how to mount your device we could of course think about implementing a mechanism to automate this. I assume it would be likely that also other users would benefit from this.

PS. DCRainmaker would have to file a load of issues for all his devices 😄

[gotiniens]

There are clearly some differences, all taken from gio mount --list --detail:

• your device exposes only an Volume, mine an disk with an sub volume
• Your volume is of the type: GProxyVolumeMonitorMTP, mine from the type: GProxyVolumeMonitorUDisks2
• your volume has should_automount=1 mine should_automount=0
• your volume has an activation_root value
• your volume has an ids.unix-device value

I don't really know the significance of these differences, but I think that the ids.unix-device is used to match on the /dev/bus/usb/001/006 parameter give in the gio mount command. Maybe it is possible to add this value to the device?

Yes my Ubuntu machine auto-mounts my device on the path: /media/tim/GARMIN. Trying to replicate the behaviour manually I found the following:

• The gio command fails, with an error which indicates my theory about the ids.unix-device seems to be right

gio mount -d /dev/bus/usb/001/012
gio: /dev/bus/usb/001/012: No volume for given ID

• I was able to mount it with the udisksctl mount -b /dev/sda command (No output, having some problems right now)

But I was also able to use the udiskctl command on the raspberry, but it needed user interaction:

pi@raspberrypi:~ $ udisksctl mount -b /dev/sda
==== AUTHENTICATING FOR org.freedesktop.udisks2.filesystem-mount-other-seat ===
Authentication is required to mount Garmin FR920 FLASH (/dev/sda)
Authenticating as: ,,, (pi)
Password: 
==== AUTHENTICATION COMPLETE ===
Mounted /dev/sda at /media/pi/GARMIN.

Luckily there is an --no-user-interaction option, too bad it does not work:

pi@raspberrypi:~ $ udisksctl mount -b /dev/sda --no-user-interaction
Error mounting /dev/sda: GDBus.Error:org.freedesktop.UDisks2.Error.NotAuthorizedCanObtain: Not authorized to perform operation

Conclusion

• I don't think it is possible to add the ids.unix-device value for devices not exposing them.
• So I think the udiskctl route is the way to go, but we have to solve the needed user-interaction.
• Using udiskctl for your device seems to not be possible (no block device), so some sort of detection of the two methodes seems to be needed
• After that we should also figure out something for the different mount paths? watching multiple paths, bind mounts, etc

[gotiniens]

I also found pmount /dev/sda garmin which mounts the device under /media/garmin.

I have a feeling it uses udisks API calles. but I have to check that

[fgebhart]

I also found pmount /dev/sda garmin which mounts the device under /media/garmin.

I assume it mounts your device at your ubuntu machine, right? Because once you are able to mount your device at the Raspberry Pi we can get started with automating it.

As long as we manage to get the workoutizer API endpoint mount-device triggered (via e.g. udev), we should be able to parse the output of one of the above commands (e.g. gio mount --list --detail) and from that output we should also be able to distinguish which device was connected and thus decide on the different mount options.

For the initial break through I would leave the "Path to Garmin Device" option as is and maybe enhance the RPI setup readme in a way so that people will get to know the mount path of their device and subsequently can enter this via the settings page of workoutizer.

In a next step we could also try to get rid of the "Path to Garmin Device" option entirely, since we could figure it out automatically during the different mount options. But that is nothing to worry about currently, I would say.

[fgebhart]

Great! Let me know if you need help 🙂

With #174 Merged this issue is resolved
