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...

We start by understanding that we have to realize just what we concentrate our power on is what shows up for us. Just what we concentrate on with worry, our subconscious mind matches that fear resonance for us since we have actually put our energy, feeling, idea and also intention behind it as well as subconscious mind wishes only to focus on manifesting that "thing" we are taken part in believing after so highly.If we concentrate on what we do want and not just what we don't want, subconscious ...

analog output?

Hi,I was wondering if the NRF52832 has any digital to analog converter (DAC). I can't find any references for it.Thanks....

I have a nRF52840 application that needs to take a complex list of commands from a server. I have a few options. I could: * code a basic language myself for these commands* accept some sort of script in (python?) which means I need an interpreter* compile my commands into bytecode and ship that off to be run in ramThe scripting seems dangerous enough, but the running foreign commands in ram is risky, even if I encrypt everything the whole way.Say I did want to use load code into ram and execute it, is it ...
