- Blecon is developing advanced Bluetooth beacons that can send and receive large data payloads, designed for environments with many devices like warehouses and hospitals.
- The system uses smartphones with a Blecon-enabled app to forward encrypted data between beacons and the cloud, ensuring communication even without dedicated gateways.
- A testbed with over 100 devices was created to ensure reliability, using Nordic Semiconductor nRF52840 Dongles for cost-effective and scalable testing.
- The testbed includes an orchestration framework for monitoring, firmware updates, and performance data collection, ensuring continuous operation and reliability.
- Over-the-Air (OTA) updates are rigorously tested to ensure they work reliably, with a two-step OTA process to catch potential issues early.
- The system includes crash reporting via Memfault to quickly identify and fix bugs, and the testbed serves as a continuous status indicator for the engineering team.
