Troubleshooting

Q: i can not update my watch/its stuck/acting weird

Have you tried to reset the watch? there are 3 ways to do it

1. Restart watch from app. under update there is a restart button (it says reset but it restarts and keeps all your settings)
2. Reset from watch (Last menu point, this resets everything)
3. Hard reset (connect charge cable and press up and down button to reset)

Force OTA update:

1. Connect your watch to the charger. (watch must be charging)
2. Press all 3 buttons on the side simultaneously
3. Release the 2 side buttons, and keep the middle button pressed until you get the upgrade connecting display. (this might take some seconds)
4. Delete connection from phone
5. Connect and pair from app and upgrade
6. If you are on an Android device and it cannot connect, try an ios device, and vice versa

Q: The watch keeps switching back to chinese

More people have experienced that if the language is non english the watch will reset to chinese. Changing the phone OS to english stops the watch from switching to Chinese.

How To install GoClever Chronos ECO firmware on Weloop tommy (android only)

1. Download latest ECO firmware to phone
2. Disconnect Watch from phone, install ECO app
3. Go to “Check For Upgrade”
4. Tap on the middle circle six times
5. “Select a firmware file___ [Browse]”
6. Watch must be in forced OTA
7. Update watch.
8. You can flash between weloop and Goclever firmware (always be careful and follow instructions when flashing, i take no responsibility for bricked or exploding watches...)
9. To install weloop firnware, follow same instructions but use weloop app instead.

PROJECT OPEN FIRMWARE (please make sure you understand what this is and what it does before you attemtp to flash your watch)
Make a Weloop Tommy an open source sport watch that can be used without a mobile phone. Want to see a heart rate when running, cycling speed and cadence when cycling or number of laps while swimming? Help to make it possible! LINK
This project is divided into six phases:

• Phase 1: find out and document watch pinout so it will be possible to communicate with screen, accelerometer and a flash memory from a custom firmware. DONE
• Phase 2: write a custom firmware that will print sample text on a screen and expose a BLE service. Firmware will be flashed using SWD connector. DONE
• Phase 3: make it possible to upload a custom firmware using OTA. This will save the waterproof case from destruction. DONE
• Phase 4: update softdevice to the newest version (S110 8.0.0). Add possibility to switch to other softdevice (S120/S130) DONE
• Phase 5: create a "terminal" firmware that allows to control what is displayed on a watch from an android/iOS app. IN PROGRESS
• Phase 6: create a "standalone" firmware using S130 softdevice that can connect to external sensors (HRS, CSCS etc) without a phone. TODO

BUGS & Annoyances

• Notification not always deleted from phone when deleted on watch
• Watch freezes sometimes
• Being able to set the night time manually would be great (This can be done with the Goclever fw)

I'm no Dev so I'm not sure if this is of any help. While updating the watch I wanted to ensure my screen stayed on so I was tapping the screen.

If you tap the center of the percentage 6 times a pop up appears for you to select your update file. If you select browse it gives you access to a bunch of folders that appear to be inside the app or maybe the watch itself. I tried it several times and 6 is the magic number to make the option appear or disappear. It doesn't work if the watch isn't upgrading it's firmware.

Hope it can be of some use

backlight

first of all thanks for this thread :good:

the nite backlight on my tommy watch actually comes on after 5PM (17:00)
i am from Slovakia, phone language is English, time zone CET (GMT+1)
interesting to see that yours turns on after 23:00

Hello! Can someone make last CHRONOS ECO apk link to download? I cant download it from google play.

Hello! Can someone make last CHRONOS ECO apk link to download? I cant download it from google play.

Hi , the chronos eco app is not compatible with the Weloop Tommy.

 

[l.capriotti]

Brand new Tommy, it was paired with my phone but the connection was unstable, so I tried and forced an OTA update, watch is "Updating... 0 pct" but now the phone cannot detect the watch any more
Resetting the watch will restart it in ota update mode again!

Any help appreciated...

Happened to me also, try to delete connection under bluetooth settings on device. now connect to to weloop and pair from Weloop app. keep trying and then go to update. again persistence is key. keep trying to update suddenly it will connect and update.

Whas the watch on latest firmware when you tried the force OTA?

are you on android or ios see if there is an updated App for you phone. see link on OP for beta APK.

let me know if it works.

 

[l.capriotti]

watch was not on latest firmware, cant' remember which version it had.
I'm on android, also v1.24 does not help as check for updates does not go beyond "Checking version...".

Try to update the Weloop app, latest is 1.27.
kill weloop app
delete bt connection from phone.
Open weloop app
conmect and update. Keep trying it can take a couple of times.

If all fails if possible try with other device and or ios device

 

[l.capriotti]

update: I used an iphone and after a few retries I got it on v3.18.
back to android, but the pairing and the sync is problematic, to say the least, on my Huawei P7...

If it's allowing you to select an update file, surely it is showing you the file system of the phone? Otherwise, you'd have no way to put a firmware update file there to select. My understanding would be this allows you to install a firmware update file stored on your phone, although I can't test this for sure as my Android phone is currently being repaired. There's some discussion about this here and that thread also contains a very small amount of analysis on the firmware file (VERY small amount, basically just analysing the name of the binary file), and another app that is apparently in some way related (link).

For what I can glean from the description of that app (seemingly made by the manufacturer of the SoC [System on a Chip] used in the WeLoop Tommy), it would appear that devices using the SoC (including the Tommy) have three firmwares: "bootloader", "soft device" and "application". The one embedded within the WeLoop app apk has the name "ble_app_ancs.bin"; ble stands for bluetooth low energy and ancs apparently stands for apple notification centre services. That leaves "app" - my guess would be this is the "application firmware". I'm not entirely sure the roles of the "bootloader" and "soft device" firmwares, but my guess is the one or other allows the device to get into "DFU mode" (or "OTA mode" as it seems to be referred to also), meaning in theory it should perhaps be possible to recover from any bricks arising from flashing dodgy application firmwares.

So potentially there is the option of reverse engineering the firmware (easily obtained from here: http://wtf.li/ - mirror of the APKs of the app [each of which contain a version of the firmware], and also one version of the firmware (the .bin file) separately), and creating a custom/modified one, while still being able to recover (because bootloader & soft device should be untouched). However, I have neither the expertise nor the time to look into that.

Without an Android phone with which to run either of the apps right now, I can't poke about too much (I only received my Tommy today), but once I get my phone back I'll maybe try and see if I can find anything else interesting. I'd like to see if I can figure out any way to get access to the watch faces, and see if they can be reverse engineered in any way, for example.

EDIT: Here is the output of strings run on the firmware binary from the latest version of the app on http://wtf.li : http://pastebin.com/X7TQXTb3 - nothing particularly interesting, a few filenames of the source files and a few other strings seen in the watch interface and stuff.

EDIT: A couple of URLs accessed by the app (seemingly related to updating):
http://au.umeng.com/api/check_app_update
http://www.yfsmart.com/weloopInterface/getFirmware.do

I can't see anything on these sites, my guess would be they need query strings parameters or something (not really sure what, some way of identifying that the app is accessing the site) to actually do anything.

EDIT: Hmm... http://www.yfsmart.com/weloopInterface/firmware_Upload.jsp - this site seems to allow you to upload a firmware. I wonder if it allows anyone to upload a firmware, which would then be downloaded by everyone when they check for updates? Certainly seems rather insecure...There's a bunch of other pages at http://www.yfsmart.com/weloopInterface/ haven't looked through them all yet.

EDIT: From what I can glean from this page ("SoftDevices" section under the "Development Tools and Software" tab), it seems like the "soft device" firmware is essentially a bit like a library, it's a precompiled binary supplied by Nordic (company that makes chip inside Tommy) which provides all the networking functions etc. which the "application" firmware uses. So:

application = front end UI (basically, the part WeLoop made)
soft device = "library" via which application can access hardware etc.
bootloader = initial part of firmware that loads SD + app firmwares

So the only really interesting part is probably the application firmware, the part that is in the WeLoop app. That's the code that actually "matters", the rest is just low level stuff. For actually changing the interface or whatever, modifying the app firmware would be all that's needed (for example, to increase the font size or the back light duration etc.).

Thank you for the insights and findings its all very promising. :good:
On a sidenote:
I talked to one of my colleagues who is an engineer (i'm not a dev but a Designer), it seems like we in the office are playing around with the exact same SOC from NordicSemiconducter. we tried one of the apps from the google play store and it connects to the weloop(see attached pic). The app was called "nRF Master Control Panel", tried the other apps from NordicSC but no luck.
Hopefully there will be some sort of SDK with the v3.0 release on the 30th...

 

[SifJar]

I got my Android phone back today, and haven't tinkered too much with Tommy just yet, but I can confirm that the file system you are browsing when you tap the percentage 5 times during an update is just the phone file system. It browses from root (i.e. /), rather than /sdcard or whatever, which is the standard, user accessible partition, hence there are some folders etc. you may not recognise, but amongst them will be "sdcard" which will take you to your regular storage (note: this is the case on phones without a micro SD card as well), where you could easily place an update file.

Troubleshooting

Force OTA update:

1. Connect your watch to the charger.
2. Press all 3 buttons on the side simultaneously
3. Release the 2 side buttons, and keep the middle button pressed until you get the upgrade connecting display. (this might take some seconds)
4. Delete connection from phone
5. Connect and pair from app and upgrade
6. If you are on an Android device try an ios device, and vice versa

I tried to use the OTA update to go from 3.17 to 3.18 (on Android) but Tommy stuck on screen "WeLoop ... Udating 0%", my smartphone (HTC M8) with its APP (latest version) dont find the Tommy and it remains bricked, how do I restart it? I tried all combinations, but remains on the screen, help me!
