Nordic Semiconductor, the manufacturer of the SoC chip in most beacons, has a new blog post on Large scale Bluetooth mesh testing.
Tests were conducted in Nordic’s office in Trondheim and focussed on measuring reliability and latency. The results show that it’s easy to get 100% reliability for unacknowledged messages. Regarding latency and reliability, unacknowledged messages perform better than acknowledged messages within the used testing constraints.
