The Sentii app allows a user’s smartphone to act as a gateway between Sentii sensor beacons and the Sentii web UI. When running, it will scan using Bluetooth (BLE) for nearby Sentii sensor beacons that have been assigned to a shipment using the Sentii web UI, gather the collected sensor data from the beacons along with location data from the phone, and update the corresponding dashboard on the web UI via the phone’s cellular or WiFi connection.

Upon opening the Sentii app, there will be a prompt to name the device. This can be whatever you like, and will be sent with the data to the web UI.

There will also be a warning message to guide the user to where they can allow the app to ignore battery optimizations, to try to avoid having it delayed when the phone dozes.

Please note that even with this setting, the Sentii app may still get delayed if the phone enters doze mode after sitting idle for a long time depending on your model of phone and version of Android. To ensure that the Sentii app continually sends regular updates over a long period of time, the phone should be plugged in and charging.

This step may be different depending on the model of the phone. For example, on LG phones, the prompt brings the user to the “Power saving exclusions” page, where tapping on the Sentii app excludes it from battery optimizations.

Whereas, on Samsung phones, the prompt brings the user to the “Optimize battery usage” page, where after selecting “All apps”, the user can tap on the Sentii app to disable battery optimization.

Upon returning to the Sentii app, tapping Start gets the Sentii app to start running and scanning for Sentii sensor beacons. If necessary, it will prompt the user to give it access to Location services for tracking purposes. The user should select "Allow ll the time" in order to receive location updates while the app is in the background.

Tapping Stop will stop the app from running. It will try to send out any data it has collected, so the button might spin for a while before the app fully stops. ## Permissions and access ### Permissions - `android.permission.ACCESS_COARSE_LOCATION` - `android.permission.ACCESS_FINE_LOCATION` - `android.permission.ACCESS_NETWORK_STATE` - `android.permission.BLUETOOTH` - `android.permission.BLUETOOTH_ADMIN` - `android.permission.BLUETOOTH_CONNECT` - `android.permission.BLUETOOTH_SCAN` - `android.permission.CAMERA` - `android.permission.FOREGROUND_SERVICE` - `android.permission.INTERNET` - `android.permission.REQUEST_IGNORE_BATTERY_OPTIMIZATIONS` - `android.permission.WAKE_LOCK` - `com.google.android.finsky.permission.BIND_GET_INSTALL_REFERRER_SERVICE` ## Similar extensions and apps - [Sentii Viewer](https://chrome-stats.com/d/com.acamp.coldchase.viewer) — 28 users - [Sentian](https://chrome-stats.com/d/za.co.sentian.Sentian) — 703 users - [Kea Tracker](https://chrome-stats.com/d/com.captemp.kea) — 149 users - [SINTRA - Beacon Read](https://chrome-stats.com/d/com.sintra_read_beacons.Ui) — 239 users - [mySentinum](https://chrome-stats.com/d/com.my.sentinum2) — 26 users - [viaSens](https://chrome-stats.com/d/sauter.automation.smartsensor) — 643 users - [OnSight Connect](https://chrome-stats.com/d/nz.co.onsight.onsight_mobile_gateway) — 22 users - [BeaconTech](https://chrome-stats.com/d/com.BeaconTech.BeaconTech) — 8 users - [SIMULATORE BEACON](https://chrome-stats.com/d/com.tapmylife.tap_simula_beacon) — 189 users - [Sentio Sidekick](https://chrome-stats.com/d/com.sentiosidekick) - [Sentorise](https://chrome-stats.com/d/com.chiptrip.sentorise) — 555 users - [Kea Tracker](https://chrome-stats.com/d/com.captemp.keatracker) — 28 users --- Source: [Chrome-Stats](https://chrome-stats.com/d/com.ColdChase)
