Content of this blog based on the documentation of BLE Secure DFU example and Bootloader module library in our SDK. Here we provide you with step by step introduction to make it easier to follow and test Secure DFU.The Secure DFU is the new DFU bootloader provided from nRF 5 SDK v12. The old bootloader in SDKv11 and earlier is called Legacy DFU. Secure DFU is not backward compatible with Legacy DFU. What you would need to prepare before we start: Up to date nRF5 SDK (minimum SDK v12) Python with...

The new Bluetooth 5 specification promises twice the speed and 4 times the range. Doubling the speed is achieved by increasing the on-air datarate to 2Mbps, while quadrupling the range is achieved by lowering the bitrate to increase the sensitivity of the receiver. We at Nordic have made a demo showing these features with our newest SoftDevice(s) and specifically our newest chip, the nRF52840. It was showcased at CES 2017 in January.Here is a more in depth description of the demo.The demo is based on the ...

PolyMCU is an Open Source Framework which has been designed to be as flexible as possible: host OS independent (support Linux, Windows, MacOS), support any toolchain (GCC, LLVM), any RTOS (ARM RTX, FreeRTOS), any micro-controller vendor SDK (Nordic Semiconductor, NXP, Freescale, ST). The framework is based on Cmake.One of the major benefit of the framework is your firmware development is unified across the different development environment and MCU Vendor SDKs.PolyMCU is not ano...

Hi,I currently try to build a little thread network with a border router bridging to ethernet. I did everything like in the Border Router Quick Start Guide and as far as I can say, everything works fine. My problem is now that I need to reach the CoAP server from outside via IPv6. Is there a 'simple' way to modify your example to forward IPv6 prefixes?RegardsCaspar...

Hello,According to the nRF Sniffer Guide 1.2, the sniffer is supported on a number of platforms (nRF51822/nRF51422 Evaluation Kits and others). All of them (as far as I could see) are marked as 'not recommended' on the Nordic product web page. The listed distributors (Mouser, Avnet, Digikey, etc.) do not have them on stock anymore.What are the recommended replacement HW platforms for the sniffer?Thanks,Norbert...
