Bluetooth Mesh Network

In this post, we’re continuing our tutorial series on Bluetooth mesh (you can find part 1 here and part 2 here). This will be the final post that will cover “theory only” content — in the upcoming posts we’ll start digging into more practice by implementing a Bluetooth mesh example on the Nordic nRF52 series platform.…

Understand BLE connection intervals and events in under 5 minutes A BLE connection interval is the time between two data transfer events (BLE connection events) between the central and the peripheral device. The theoretical value ranges from 7.5 ms to 4 secs (with increments of 1.25 ms). A few notes regarding BLE connection intervals: The connection…
