OpenTrace Android app. Reference implementation of the BlueTrace protocol.

OpenTrace Android app

OpenTrace is the open source reference implementation of BlueTrace. BlueTrace is a privacy-preserving protocol for community-driven contact tracing across borders. It allows participating devices to log Bluetooth encounters with each other, in order to facilitate epidemiological contact tracing while protecting users’ personal data and privacy. Visit https://bluetrace.io to learn more. The OpenTrace reference implementation comprises:

• Android app: opentrace-community/opentrace-android
• iOS app: opentrace-community/opentrace-ios
• Cloud functions: opentrace-community/opentrace-cloud-functions
• Calibration: opentrace-community/opentrace-calibration

Setup of the app

To get started on the app, setup and configure the following:

1. ./gradle.properties
2. ./app/build.gradle
3. Firebase - google-services.json

How does this solve scanning while the device is asleep?

Hi, I'm struggling to understand how your implementation manages scanning while in background. There is no wakelock and the repeated scan scheduling is implemented via simple handler messages. To my understanding this won't work when the device goes into sleep.
I now work on a similar app and we solve theses problems by keeping the device awake as we really want to make sure the scanning works continuously and reliably. Obviously it comes with some extra battery drain. That's why I'm trying to understand how you cope with this and if perhaps continuous scanning proved itself as not necessary.

Android device didn't find ios device

Hi there,
I was config android and ios app. I had records in firebase with upload data from ios and android app. But Android device just have android's records. Ios device just have ios's records.
Please help me.
Thank all!

Support for "external" Bluetooth Low Energy hardware

Hi all,

A silly thought… I have an older mobile device which is too old to run OpenTrace (or its "branded" variants, TraceTogether, COVIDSafe…) on a count of its OS (Android 4.1) and its hardware (Bluetooth 3.0 radio). It's not worth me buying a new phone just to run this application, however, it would seem BLE-capable microcontrollers (e.g. ESP32, nRF52832, nRF52840) are cheap and readily available.

I had a quick read of the BlueTrace whitepaper, and I suspect it might be possible to "cleave" OpenTrace into two parts: the phone app that talks with the "cloud" server, and the radio part that does the BLE handshakes.

The thinking is we could make a hardware device that, independently of the phone, manages the contact tracing functions (thus neatly side-stepping problems like issue #31), and either just connects to the Internet via the phone in WiFi hot-spot mode, connects to the Internet via the phone using Bluetooth LAP (for real old non-Android "feature" phones) or periodically connects to the phone app via Bluetooth RFCOMM.

If a firmware for commonly available BLE dev boards could be developed, these could be packaged and made available during this COVID-19 crisis, then once everything's over, those boards then sold onto the maker community to be re-purposed.

I have a couple of Nordic nRF52840 dev boards kicking around as well as an ESP32 board (Adafruit module if I recall correctly), there's a old phone (ZTE T84) with a dickey battery that I can perhaps try running OpenTrace on for interoperability checks and I'll look into getting a test set-up going with the "cloud" server.

I'd love to hear from others who'd be interested in assisting with this.

Stuart Longland

How to decrypt MSG

Hello,

i have an issue decrypting the msg attribute once it's stored. i want to decrypted once i get the records in firestore.

Thanks

How to test if its working?

I have just installed the application on an android phone, how do I test if the application's bluetooth feature is working? Can I test with TraceTogether application found on playstore or must both applications be installed from github.

OTP is correct and the time is not expired. It still shows the code has expired

1. Before entering the OPT the message shows "Verification failed. Please try again"

2. Then after entering the OTP, message shows "Wrong OTP entered"

Execption I get at console- com.google.firebase.auth.FirebaseAuthInvalidCredentialsException: The sms code has expired. Please re-send the verification code to try again. -ERROR_SESSION_EXPIRED

After that an user upload the data , how to retrieve the uid or phone number of the user who upload and uid or phone number of other users who is in upload data of this user .

Wrong OTP entered and OTP expired on debug lofs

Hi Guys,
When I try to register the app I get wrong OTP, I am 100% I type it right and when I look at debug logs O get the message below:

 com.google.firebase.auth.FirebaseAuthInvalidCredentialsException: The sms code has expired. Please re-send the verification code to try again.
        at com.google.firebase.auth.api.internal.zzdv.zza(com.google.firebase:firebase-auth@@19.2.0:30)

Can you please assist or I am missing something.

SMS not received from firebase for phone authentication

Hi,

First of all, I'd like to thank all the contributors to the discussion and specially the Gov of Singapore for publishing OpenTrace open source.

I've gone through all the README.md both for OpenTrace Android and OpenTrace-cloud-functions.

1 - npm --prefix functions test works fine

config.ts
#encryption
√ should have a valid default algorithm
#encryption
√ should succeed in getting encryption key (880ms)
#upload
√ should have valid buckets (829ms)
#upload
√ should use a good pin generator

4 passing (2s)

2 - firebase deploy --only functions works also fine

• functions: Finished running predeploy script.
  i functions: ensuring required API cloudfunctions.googleapis.com is enabled...

• functions: required API cloudfunctions.googleapis.com is enabled
  i functions: preparing functions directory for uploading...
  i functions: packaged functions (109.19 KB) for uploading

• functions[getTempIDs(europe-west2)]: Successful create operation.

• functions[getUploadToken(europe-west2)]: Successful create operation.

• functions[processUploadedData(europe-west2)]: Successful create operation.

• Deploy complete!

My trouble when starting to test Opentrace :
After entering the phone number for registration. My device does not receive the SMS code from firebase.
I've enabled Phone authentication and put the SHA-1 as necessary..

Still no SMS has been sent from firebase.

When I tested with whitelisted phone numbers, I can register.

Could someone tell me what could be the missing point here ?

Thanks for your helps

PURGE_INTERVAL & PURGE_TTL missing from example gradle.properties "file"

...but after adding those managed to get app imported into Android Studio properly!

Thx!

Undocumented settings / config

In the readme, you mention:

STAGING_SERVICE_UUID = "17E033D3-490E-4BC9-9FE8-2F567643F4D3"
V2_CHARACTERISTIC_ID = "117BDD58-57CE-4E7A-8E87-7CCCDDA2A804"

What do these two variables stand for exactly? It's not clear to me what values I should set for my app.

Thanks.

Bluetooth services

Hey, is it possible to use the bluetooth feature of the application without the cloud functions? Will the Bluetooth feature where one device running open source openTrace and another device running TraceTogether from the playstore be able to communicate and log their encounter?

Possible GPLv3 license violation by COVIDSafe App?

The Australian Government has released the source code for their COVIDSafe app which looks based around OpenTrace's source code, but I can't find the GPLv3 license in their repository and their license seems to violate clauses in the GPL? Can anyone with more knowledge comment on this? The COVIDSafe repositories can be found here.

Year 2038 problem

I observed from the white paper and TemporaryID that the startTime and expiryTime are effectively 4 bytes, i.e. Unix time (seconds).

Since this will overflow on 19 January 2038 (18 years later!), if we want BlueTrace to still be used during pandemics then, we should fix this and use 8 bytes instead.

Creation of 'users' collection and adding a new user to database after registration

Hi,

How would I go about creating a 'users' collection and adding a new user's details to the collection after successful registration? To be more specific, where exactly would I have to put in the code for writing to the DB?

StreetPassRecords Always Empty when uploaded

I am trying to set-up the whole project. Whenever I upload the data from one device keeping another device beside for a while, this is uploading an empty array of street pass records. To. be exact, none of the overridden methods of BluetoothGattServerCallback is getting invoked. Am I missing any steps? Thanks

opt issue

from the debug screen.. i am getting this message when testing for the OTP
anyone can help please.

Decrypt msg to uid

We have shared a reference implementation for processUploadedData, you can find the logic to decrypt exchanged messages to uid here:

https://github.com/opentrace-community/opentrace-cloud-functions/blob/master/functions/src/opentrace/processUploadedData.ts#L104

not able to understand how to use logic
how to get uid or mobile no. from street past record>msg, or how to decrypt encrypted msg

Sure. There's a file called CustomEncrypter.ts with a decryptTempID, you can find more decryptions. you can look there and i'm sure you are going to find a solution

Originally posted by @ie76 in #13 (comment)

how to call that and put msg argument, do i need to do it from command line from cloud function directory in my local machine
or from the firebase test section

Why using a BLE manufacturer ID assigned to a private company?

In io.bluetrace.opentrace.bluetooth.BLEAdvertiser.kt, the following code builds the AdvertiseData which a manufacturer ID = 1023 and 3 bytes of random manufacturer specific data.

val randomUUID = UUID.randomUUID().toString()
val finalString = randomUUID.substring(randomUUID.length - charLength, randomUUID.length)
CentralLog.d(TAG, "Unique string: $finalString")
val serviceDataByteArray = finalString.toByteArray()

data = AdvertiseData.Builder()
.setIncludeDeviceName(false)
.setIncludeTxPowerLevel(true)
.addServiceUuid(pUuid)
.addManufacturerData(1023, serviceDataByteArray)
.build()

The Manufacturer ID 1023 seems to be assigned to a company called Withings (www.withings.com), according to https://www.bluetooth.com/specifications/assigned-numbers/company-identifiers/

Would this cause any legal issue with Withings?

Thanks,
Yuan Huang

Invalid Pin on upload section

I get invalid pin when a put the pin for upload. I use storeUploadCodes() to store the pin and i can see in firestore the
Crypted code but when i enter it in the app it still write invalid pin. I changed the format date to 'yyyyMMdd' under uploadToCloudStorage in EnterPinFragment.kt but i still get invalid pin.

Records and Status is always empty

I am able to register & upload data on the Firebase storage, the problem I am facing is records & status is always empty in json file.
{"records":[],"events":[],"token":"XXXXXX"}

How am I testing the app:
I have installed the application on 3 devices, registered and kept device bluetooth on, on all the devices, after 20-30 minutes I uploaded the data from all 3 devices and all 3 json files has empty data. ({"records":[],"events":[],"token":"XXXXXX"})

I debugged the application while uploading and found database is empty, I don't see any errors also in logcat.

Generated 3 UUID using https://www.uuidgenerator.net/version1 and configure for below properties:
STAGING_SERVICE_UUID
V2_CHARACTERISTIC_ID
PRODUCTION_SERVICE_UUID

can anyone suggest what should be the issue? Thanks.

Tracing is unreliable once the phone is in your pocket

Ok, so my apologies if this is not correct, I have not yet read all of your code BUT...

Based on my quick look at your manifest and what I saw with setting up background tasks I don't think you will be able to get the Android version of your application to scan consistently. When Android puts the app into Doze mode your alarm manager won't wake up the app to scan. You can fix that and you can scan at any frequency you want using Alarm Manager even when the application has been killed or the handset has been 'Dozed'. Here's the basics:

add.. to your manifest.

Don't use Alarm manager to schedule a repeating task. Instead, use it to schedule one task at a time with a delay, BUT in the task, schedule the next task. Also in the broadcast receiver you'll need to take the wake lock. I'm going to take a more careful look at your code later today. Please let me know if you would like help fixing this; I've already implemented it this way in our social distance app and it will work here too.

What am I missing?

Activity class {io.bluetrace.opentrace.stg/io.bluetrace.opentrace.SplashActivity} does not exist.

Hi Guys,
The App fails to startup on AVD, although works fine from my phone except I can't pass the part I pout my number to wait for OTP, it fails with message below:

04/10 20:30:46: Launching 'app' on Pixel 2 API 28.
$ adb shell am start -n "io.bluetrace.opentrace.stg/io.bluetrace.opentrace.SplashActivity" -a android.intent.action.MAIN -c android.intent.category.LAUNCHER
Error while executing: am start -n "io.bluetrace.opentrace.stg/io.bluetrace.opentrace.SplashActivity" -a android.intent.action.MAIN -c android.intent.category.LAUNCHER
Starting: Intent { act=android.intent.action.MAIN cat=[android.intent.category.LAUNCHER] cmp=io.bluetrace.opentrace.stg/io.bluetrace.opentrace.SplashActivity }
Error type 3
Error: Activity class {io.bluetrace.opentrace.stg/io.bluetrace.opentrace.SplashActivity} does not exist.

Error while Launching activity

I am also failing to register, after putting my phone number, it doesn't go anywhere plus there are no error messages. Am I missing something.
Thanks you,
Jongi

Lower minSdk from 22 to 21

According to the android doc, Low energy Bluetooth is supported since api 21. Is there any reason why we cannot low the sdk to 21?

Pin for Uploading data

There is some documented procedure describing how to generate pin to upload data?

Bluetooth permission and enabling

Is the permission for Bluetooth taken only once and Bluetooth is enabled for all times unless permission revoked?
Is there a way to ask for Bluetooth permission once and if allowed by user, then enable Bluetooth at regular intervals without asking again and again?

Can not get txPower value

I tried to get txPower in onScanResult(callbackType: Int, result: ScanResult?) callback but the value alway is TX_POWER_NOT_PRESENT (127)

May I do anything in wrong way?

f-droid.org repository

It would be great if opentrace would be in the f-droid repository. It similar to google play, but only contains freesoftware (like opentrace is).

No physical device

Hi Everyone,

I currently dont have a physical device and was setting up just using android studio. Given the importance of bluetooth this was an immediate show stopper during setup (I made it past the otp screen after setting up in firebase).
I have tried launching the app using an android image on virtual box but again i am having issues with bluetooth. In both cases after the OTP screen where i am asked to give permission to access bluetooth the app resets to first screen.
Has anybody been able to work with the app without a physical device? If so what was your setup?

Thanks

No communications happen between an Android phone and iOS phone running the app

I have managed to build the application on both Android and iOS. The app is running on two iPhones and two Android phones. The two iPhones communicate with each other through Bluetooth and so do the Android phones, however, I haven't been able to see any records for communication between any of the iPhones with any of the Android phones. Am I missing anything here? Is there any specific configuration that needs to be the same on both builds? Is that communication not possible by design, at all? U can provide further information about the two builds upon request.
