A persistant problem that people using the C++ compiler from the "GNU Tools for ARM Embedded Processors" toolchain has been the way that G++ handles the inline-assembly for the SVC instruction.Specifically, you get an impossible constraint in 'asm' error when trying to use any softdevice header.There have been a few questions about this here on the Nordic Developer Zone, here for example, with putative answers on StackOverflow.However, myself and others have found that the "insert a cast&qu...

The article introduces how to use the OTA (over the air) DFU in iOS.Step1, Connect your iOS device to iTune Select Apps, Drop App List to bottom, and select the “nRF Toolbox” app in the “File Sharing”. Drop your HEX file to the “nRF Toolbox Documents”, or click [Add] to add your HEX file. Click [Sync] to synchronize the HEX file in to your iPhone. Step2, Select DFU in the nRF-Toolbox App in your iPhone.Step3, Step3.In DFU section.Click the “Select File” to selec...

I've been looking for information on GCC support for the DFU bootloader examples in SDK v7.2.0 for the BLE Dongle board(PCA10031) but unfortunately there's nothing in the SDK. I've found a couple of GCC DFU bootloader projects online but they're all for SDK v6 and below and no longer work after the major refactor of the SDK past v7.I was wondering if Nordic had a GCC DFU bootloader project for SDK v7 somewhere that I haven't found and, if not, does Nordic have any plans to build one? It'd really save my b...

Hi, The examples provided seem to indicate that the NRF51822 needs to be attached to an application processor / CPU (e.g. - Raspberry Pi). How much resources (CPU cycles and RAM) are left over on the NRF51822 after handling the ipv6 stack?Thanks...

Hi all,I'm building an application for IOS & Red bear lab BLE shield and Arduino. The phone acts as a remote control for a toy car that I built . It works decently, but I would like the response time to be faster. I want to make the data transfer rate faster between the phone and the arduino. Please let me know if there is any way I could speed up the data transfer rate. It takes around 1/4 a second to get the data from the phone to the arduino**This is How I am sending the data from the phone** UInt8...
