NotificationUpdateApp 📱

This is a test application for testing delivering updates on BLE devices via ANCS using live activity or push notifications with collapse id.

See more about ANCS here, and about live activity here

Environment 🔨

• iOS 16.1
• Xcode 14.1
• BLE device (with firmware that print logs in real-time in the console)

• Press (+) to create a new key, give it a name and select [Apple Push Notifications service (APNs)]
• Press [Register] and download the .p8 file while saving the Auth Key ID somewhere safe
• Convert .p8 key to .pem key using openssl pkcs8 -nocrypt -in AuthKey_XXXXXXXXXX.p8 -out AuthKey_XXXXXXXXXX.pem
• Move *.pem file in folder with *.sh files
• Open sendUpdateToLiveActivity.sh and sendPushWithCollapseId.sh in some editor
• Change TEAM_ID to your Apple Developer Team ID
• Change TOKEN_KEY_FILE_NAMEto the .pem file generated in step 4
• Change AUTH_KEY_ID to the Auth Key ID from step 3
• Change TOPIC to the bundle ID of your app (MAKE SURE to keep .push-type.liveactivity at the end in sendUpdateToLiveActivity.sh file!)

Preparing BLE device:

• connect BLE peripheral to your PC (for macOS you can use screen command, see for more details)

Example:

screen /dev/cu.usbserial-A10LTYXX 115200

• make sure that you see logs from your BLE device in the console

Testing 👨‍💻

• Build and run an application (live activity should start automatically)
• Connect to the BLE device which contain ANCS and prepared on the previous step
• After successfully connecting application should open Token details screen
• Open the terminal and segue folder with bash files (sendUpdateToLiveActivity.sh and sendPushWithCollapseId.sh)
• Tap on a label with the bash command to update live activity or send a push notification

Bug description 🐛

Actual result: I received only push notifications that appeared on the screen the first time, the rest of the updates I didn't receive at all

Expected result: when I send live activity updates or push notifications with collapse id I should receive updates via ANCS

Troubleshooting 🔧

• If the live activity didn't launch automatically -> check in the application settings does it allowed to show, or relaunch the application
• If you didn't receive push notifications -> check do you launch an application in debug configuration, otherwise change in *.sh files APNS_HOST_NAME on release.
