MicroEJ SDK, a full-featured software solution for ultra-low-power devices
MicroEJ SDK was used to develop the Qwesteo terminal. MicroEJ provides a full-featured turnkey solution which is modular, easy to use, cloud-ready, and particularly adapted to very low-power hardware systems. The MicroEJ platform delivered for Qwesteo terminals includes the control of an E-Ink screen, a GPS, and connections to 3G, Wi-Fi, NFC, HTTP/REST networks for data collection and connection to the cloud. It took only a few weeks to develop a software application for the Qwesteo terminal with MicroEJ SDK using the Java language that dramatically eased software development.
The questionnaires displayed on the Qwesteo tablets, are managed in a very simple way through XML files used by the MicroEJ OS runtime to dynamically build the user interface on a small, low-power microcontroller-based hardware platform.
A 3-month battery lifetime
The development of Qwesteo terminals was optimized to meet a technological challenge : make the product 100% autonomous, with no power supply, so that it can be set up anywhere: shops, hotels, parks, train stations, etc. MicroEJ, at the very heart of the connected terminal and ideal for low-power processors, was a key player in this innovation.
A scalable, low-power product was developed very quickly. It enables to collect and transmit real-time data to the cloud over various connectivity networks. The software application is very easy to use and can be adapted to any customer needs and operating environments, ensuring a future-proof product. Above all, Qwesteo tablets have an exceptional battery lifetime of more than 3 months. This incredible autonomy enables the tablets to be set up in areas where recharging batteries is not easy. Customer feedback can be collected in lines in supermarkets, on shelves, in airports, or even directly in transportation vehicles!
