Garmin Xero not sending all sessions to the App?

This weekend I shot / recorded 5 sessions. I have only been able to download the 1st, 2nd and last.
My normal MO is to download each string as soon as it's done. However it would not download the 3rd or 4th session. I rebooted my phone and turned the Garmin on, then off. It would connect via Bluetooth just fine, just no data was sent.
I finally gave in and did the "update" and after that it downloaded the 5th and last session.
Also.. is there a max number of sessions you can leave on the Garmin? I have about 25 or so on there now.

Thanks guys!
 
I had a similar issue a month or so ago. As usual turned the Zero on, started the phone app, it connected but failed to upload the two new sessions. Cycled the Zero, cycled the phone, started the app, still no upload. I recorded another session and that uploaded as usual. Called Garmin support discussed the issue. They had no solution but assured me it would be passed to development. During the process the Zero had flagged the two session as being uploaded and there is no way to set that flag off to get it to upload clean. If you call support and they tell you that you are the first to report this, please point out that another member here had the issue and if you like I can send you a PM with my phone number so they can call me and verify this is happening more than once!
 
I've had this issue. It seems their sync between the unit and app is poorly coded. Based on the one time I had this issue it appeared that the unit or app or both thought the sessions were sync'd but in my case there was a communication issue during the sync and that messed with it. I can only assume once they start a sync they are setting a simple flag that it's been synced and not actually verifying the data on both devices matches, let alone verifying it with a checksum as they should be doing to assure not only it's on both ends but the data integrity is good on the app end. I wish they would give the user the ability to clear the sync and re-download everything from the unit.

@TommyD11730 to get your data off: I have yet to test this, but per the docs you should be able to download the garmin fit files from the unit to pc/mac either directly or definitely via the garmin connect app using the usb cable. Then you can use one of the conversion tools to convert from fit to csv. It's a pita over direct csv export but at least you'll get your data off the device.

Additionally I've found that on my phone if I only have cell access (like at the range vs home), communication between the unit and phone app can be problematic and cause these kind of sync issues. Now while at the range I keep my phone app closed and phone bluetooth off, which is overkill but no bluetooth, no chance they will talk to each other.

I do all my shooting then back at home I sync the app and unit and export in one step vs per session using the three dots in the session menu (before you click on any session), click export, then click the date above the sessions which selects all sessions, then click export and choose destination. I use email because then on my pc I download the file and leave the e-mail as a backup copy. This gives one excel file with a tab for every session. I verify each session is actually there in the excel, then delete sessions from both unit and app so they are clean for next range session. I choose not to use their cloud storage option, not that it would help if you can't get the data off the unit.

The more users who report this, the sooner it will get addressed. I have reported mine and will report again if and when it happens again, along with requesting an option to reset the flag. I hope you other folks will do the same.
 
Oh yeah I've talked to them, peeing into the wind comes to mind but I'm still hopeful they will put some good coders on it and actually listen to those that use these things.
 
For those interested in sending their issues to Garmin, here is a link to email their Customer Support.

Garmin Support Email for C1 Pro

At one time I had a link to an email page for user suggestions. I now cannot find it in my browser or online! If anyone has it and would post it here I would appreciate it.
 
I've used the ideas a couple times, first time sent a big list of wants, mostly around interface and app features. It was nice they fixed the update issue people were seeing where it was trying to update mid session. The unit works great, my only wants are strictly UA usability wants. Seems changes dribble in over months, but hopefully they are listening to customer wants. The one I really would like to see is the ability to clear the app of all sessions kinda like we can now export everything. Just after the select all give the option to delete all like we can export all. Preferably with an are you sure prompt ;)

If you post your other "wants" I will also send those in so they get more exposure, or send me a PM with your list.
 
@Eagle Six

Wants... hmmm I don't think I ever recorded them anywhere, just kinda randomly asked early on as I used it and since it seemed to fall into a black hole at Garmin I lost interest. But I'll try to remember some, here goes: (preference ordered top-down)

unit: add a feature to allow the user to end the current session and create a new session of the same type and bullet weight simply by holding down a button (other than power) for xx seconds. A one button push to end and start a new session.

unit to app sync: either verify sync actually did it and data matches on both unit and in the app, or give the user the ability to clear the sync and re-download everything from the unit. Both is better because not only would Garmin be doing proper verification during and after sync, it would also allow mult devices to sync all the data from the unit which could be nice as a data sharing funtion for those that wish to at the range or event.

app: add a delete option similar to the export all sessions option, be sure to include a delete all sessions confirmation prompt so the user can't accidentally delete all sessions.

app: export csv data with formulas and calculations in totals using ranges as opposed to the current simple data and totals output. This would allow the user to export all sessions then enter each excel tab, delete or hide any unwanted rows and the totals should then recalculate based on the visible rows (just as a user might experience in any normal spreadsheet). Today to get totals for only the data we want to retain we must delete or hide the unwanted shots in the app, then export as csv. This is not user friendly as it requires the user to have already done analysis in the app to determine any shots per session which should be suppressed from export. The user should be able to munge their data at a later date and in excel or whatever app they use to manipulate their data.

app & unit: if the unit design supports push from the app, update firmware and app to add the ability for the user to pre-define named sessions in the app with bullet weight and other data and push those to the unit with a like identifier (unique identifier for each session) in advance say via the sync. The idea being so the user can identify and choose each pre-defined session on the unit quickly. The app and unit can then sync the sessions with shot data at some later date or time. The idea here is to minimize or eliminate app input at or after the shoot. Most of us go with a plan in mind, then simply execute on that plan at the shoot. Order the sessions such that they are in the same order on the unit so the user can end the current session and start the next one with minimal steps, however allow the user to arrow select any predefined sessions in any order should they choose to deviate from the original order set in the app. After the shoot and sync to app, assure all session input and unit data is exported on export as csv and each set tied to the unique identifier. The idea here is the user predefines in advance rather than renaming sessions, checking boxes, or entering comments after shooting and the session is synced to the app. Having to look at timestamps and order after sync to the app to determine which session lines up with order of shooting then edit each in the app is not user friendly.

unit: if possible either save data in both fit and csv formats or add an option to export data from the unit as csv files to a device via usb giving the user a direct export option from the unit without needing an app, data conversion from fit format, or Garmin connect.
 
@jxb Thank You, all good features and suggestions. I will submit them Tuesday along with...

app, option to store data files on phone SD card in user defined folder.

app, option to usb/wifi internet connection upload to other device in xls format with formulas.

unit, (for @LVLAaron) option to setup predefined 'one button' session start. And, one button start session from the app.

And, maybe some others.....
 
Back at the range this weekend and guess what? It did it again.
So this is the chain of events best I can remember.
Shoot/end string. Turn on app and download. Turn off app.
Shoot/end 2nd string. Turn on app and download. FORGOT TO SHUT OFF APP.
Shoot/end 3rd string. Check app, oh Shoot it's still on. 3rd string not downloaded. Unable to download 3rd string no matter what I tried.
Turn off app.
Shoot/end 4th string. Turn on app. 4th string downloads just fine.
Soooooo I'm guessing in my case I had best wait till I'm done for the day, then try and take them all in 1 bite.
I'm calling Garmin tomorrow..

I don't remember ever having the app connected during shooting sessions, so I went to the garage to do a test. C1 on, app on, units connected and synced. Fired a round, it registered, closed the session and instantly it was uploaded to the app. So it would appear it is something specific to your devices, the versions, or the sequence of your sessions. BTW, the little green rubber band I used for this test logged 133.6 fps!!
