No data transferred from Sanitas SBF70
Describe the bug I bought a Sanitas SBF70 a few weeks ago, however I just cannot make the scale transfer data to my device. It shows the bluetooth logo, and I also get toasts on my deivce like the currently measured weight, and the "connected" infos etc., but nothing else is transmitted yet saved. I setup the profile as suggested in the documentation. I don't have Google Play store so I cannot test the manufacturers app.
To Reproduce Steps to reproduce the behavior:
- Open openScale (auto-connect on startup enabled)
- Step on scale
- "connected"-toast
- Nothing happens except the currently measured weight as toasts
Expected behavior I expect data to be transmitted to my device, i.e. weight, fat%, water%, ...
Additional context
- I am using the current version available on fdroid.
- The name in the app and the name indicated on the scale do match (user setup as suggested in documentation)
Debug log How I obtained the logs (maybe I do something wrong)
- Opened the app
- Opened settings and enabled save logs to file
- Disconnected bluetooth and connected again
- After connection established (bluetooth logo was visible on scale) I stepped up
- Weight readings both on scale and device match (scale recognizes my profile)
- Nothing else happens
- Scale turns off
- Bluetooth connection closes

As long as I am not doing something horribly wrong, I don't think that this is particularly helpful for you to debug, so please let me know what else I can do/provide.
@charlydelta Hi! Without btsnoop_hci.log from original app it will be impossible to tell how to communicate with this scale. Did you checked apk mirror sites?
@charlydelta Hi! Without btsnoop_hci.log from original app it will be impossible to tell how to communicate with this scale. Did you checked apk mirror sites?
But the scale is listed as a supported scale, why is it then needed to know how to communicate with it? Wasn't it already reverse-engineered?

This scale might have newer hardware or firmware (most likely both), but the scale name was not changed by manufacturer (for marketing purposes for example). There also might be a bug in openScale. Either way - btsnoop_hci.log from original app is needed to clarify that.

All right, thanks. I will try to provide the needed files asap. Thanks for your help :)
I now installed HealthCoach and reset the scale. Even though I can configure my user and everything, I just cannot fetch any data other than the weight from the scale with either app (Also the weight is just shown on my mobile, it is not recorded in either app). But there doesn't seem to be any error, since neither app reports anything. So even if I open HealthCoach and step on the scale no data will be transferred. I don't know if I just do anything wrong the whole time or if the scale is broken somehow.
I tried to snoop the BT connection, but even after hours of trial and error and reading tutorials and stuff, my phone will just not generate a log file...

@charlydelta what is your phone model and Android version?
p.s. If you have older phone (or older tablet) with older Android version then try it. Procedure to generate btsnoop_hci.log on newest Android version is a bit more tricky than on older versions.
Yes I've got a Fairphone 3+ with latest LineageOS. I don't have an older device uinfortunately. But maybe I can ask a buddy, I will see tomorrow.
Oi lads and lasses, i suffered from the same problem and i may have found a solution.
Charlydelta: bad news for you have to get Santitas Health Coach app to create a user (this step was somewhere in the 'how to' a time ago(we need a proper manual for the thing)) you may want to get it Aurora store app with spoofed google ID. Then i downgraded to 2.3.4 and everything seems to be working just fine again. Running LineageOS 16 without .gapps on a Moto G7 US version if that helps.
If it changes for some reason ill let you know.
Hello,
I have also a problem. But I'm not sure if it is the same.
I can access my Santitas SBF70 with one phone but not with the other. Works fine: Note 4 with LineageOS Android 9 App: 2.4.5 (fdroid) Cannot connect: Pixel 3 XL CalyxOS Android 11 App. 2.4.5 (fdroid)
I also experience this bug when using the latest version (and older ones) from F-Droid. But when i manually compile and install openScale then it just works and it shows all the measurements i've done. So it seems there is something different in the debug version or in the way you guys compile the apk for the F-Droid store...?
Steps i have done: clone this repository, open the android_app directory with android studio, select Build > Build Bundle(s) / APK(s) > Build APK(s), copy the file android_app/app/build/outputs/apk/debug/openScale-debug.apk to my phone and install it. Hardware: Sanitas SBF70, Poco F2 Pro with MIUI Global 13.0.2 (Android 12).
A minor update from my side: Meanwhile I bought a new phone, and the same issues still persisted. With the new phone I also have Google Play so I tested the manufacturers app. It turned out that I cannot get it to work with that either, so I assume that at least for my case, it is just a broken scale...
