Pree

Stop losing your stuff

What is Pree?

Mobile app helping to communicate with BLE devices and giving its users' location information of their stuff

Suppose you often lose your keys and spend a lot of time looking for them. How would a developed PREE app solve this problem? We have a PREE device attached to your key/car/bag etc.
The PREE devices are being produced according to the iBeacon protocol. We developed an app allowing its users to attach the PREE device to their account and establish the Bluetooth connection between your smartphone (Android or iOS) and the PREE device.
According to the received signal, the app notifies the user when they lose connection or are back in the reach of some PREE device.

Challenges & Solutions

Connection

Challenge

There are a lot of manufacturers of Android devices, and that’s why the Bluetooth behavior is different with each of them. Sometimes the connection between the Android smartphone and PREE device is established from the seventh attempt. It takes a lot of customer time.

Solution

We made the decision – to keep scanning the BLE devices and try to reconnect after every unsuccessful connection. Also, we implemented the scanning and connecting to operate in background mode. It leads to a power consumption increase, but it seems that right now, we have found a golden means for the Android platform – between strong connections, reliable data, and acceptable energy consumption.

About customer

The essential thing in the PREE app is providing the ability to quickly access and control their PREE devices. That’s why the BLE starts scanning PREE devices after user registration and attaches trackers to the user’s account.
The main page – a list of devices is available on almost all pages. This UX feature allows easy and fast access to the settings of PREE devices. Realized UX doesn’t have deep nesting pages, allowing us to have fast access to all PREE devices.

What Makes Pree Special?

1. Technology stack for Android and IOS

The whole implementation of the app is possible thanks to the open-source Cordova BLE plugin – cordova-plugin-ble-central

This plugin allows to scan, connect, and read/write information from a BLE device – in our case PREE device. We use this plugin to scan PREE devices, get the power of the received signal for every device, and set the Bluetooth pair connection for every attached device. Also, we used Google maps and Geolocation for storing and showing the actual location of the connected PREE device. All this stuff is required for the main feature – notify the user when you lose connection or get back to the range for some PREE device.

2. Our achievements

developed app which can scan/connect/read/write for PREE ble devices (iBeacon);
developed feature notifying the user when they lose connection or get back to the range with their PREE device;
developed feature which store is the last to know the location of your PREE device and rewrite it when you are back in range;
developed feature showing all the locations mentioned above on the map for every device and general map;
developed feature showing the approximate distance to your PREE device;
developed two modes for the PREE device – ‘close by’ (strict) and ‘normal’ (no strict), which depends on the distance to your PREE device;
developed a feature notifying your family member when the PREE device is lost.
