In December we published a video showing a long range test with the newly released nRF52840 chip. The video showed that the nRF52840 had excellent range, and is fully compatible with the new Long Range feature of the just released Bluetooth 5 specification. This blogpost will go into more details about how this test was done. Below is the video for those that have not seen it yet.The setup consisted of two nRF52840 Preview Development kits, one transmitter (TX) and one receiver (RX). Both kits were connec...

Program the boards Connect all the boards to the PC cd to <install_directory>nRF51_ble_broadcast_mesh_0.8.7\nRF51\bootloader Open a command window in that directory Run .\pc-util\for_loop_batch_nRF52 this will program all the boards connected to the PC. Take 4 boards off and connect to a USB hub connected to a Charger Determine the COM port of the remaining board by going to Device Manager>Ports (COM & LPT)  Use DFU over the air to program the boards.

The nRF52832 and nRF52840 devices have a built-in NFC radio which can be used for exposing data as a dynamic NFC tag (a tag with configurable data). This can be used as a standard tag type for storing a web link or a text, to launch apps on smartphones and tablets as well as for simple and secure BLE pairing (read more here). All these features are provided by the Type 2 Tag library in the nRF5 SDK.Starting from version 12.2 of the nRF5 SDK, we expanded the NFC software to support even more features. The ...
