The Brief
Fen’s client was upgrading an existing hydraulic test unit to a next-generation product. They needed to add new features including wireless data extraction from the unit and providing a mobile App to process and share the data over the mobile network.
Part of the upgrade of the existing product was a re-architecture and re-implementation of the full embedded code base.
The Solution
Fen worked with the customer to evaluate and select an appropriate BLE (Bluetooth low energy) solution that was both cost effective and technically appropriate for the requirements.
Fen re-implemented and upgraded the existing product code base to introduce the specified new features.
Fen developed a cross-platform mobile App to interface with the field unit using BLE and serve the unit’s test data over the mobile network. Fen specified and implemented a secure link protocol to discourage unauthorised third party Apps which might damage the customer’s brand.
Fen developed a PC test App to prove the embedded software solution and mobile comm’s link in parallel to, and independently from, the mobile App development process.
