As many have noticed, Keil 5 does not have native support for Keil 4 projects (project files ending with uvproj), it only has native support for Keil 5 projects (project files ending with uvprojx). However, many of the examples provided in older versions of nRF51 SDK are only supported by Keil 4, i.e. only contain Keil 4 projects. Also, many of the examples available on Nordic Github contain only Keil 4 project. It is however possible to to make Keil 5 support both Keil 5 and Keil 4 projects. These are th...

OverviewThe UriBeacon design allows a Bluetooth Low Energy (BLE) device to periodically transmit an ADV packet that contains a URI. This technology enables any device, place or thing to become a beacon through physical association. As a consequence UriBeacon enables any object in the physical world to transmit a URI over a short distance (typically 20-30 feet), and is an enabling technology to support the Physical Web paradigm. By providing discovery, search, and control (using web pages) based on ...

Since nRF51 SDK version 8.0.0 SoftDevices binary files have become a part of the release. In order to make it easier to flash proper type and version of SoftDevice a new feature was added: each project that is using SoftDevice contains additional target called ‘flash_softdevice’ which can be used to program SoftDevice. Solution works with ARM Keil uVision 4 and 5 (with and without CMSIS Packs) and Makefiles. It is ensured that SoftDevice binary file matches SoftDevice header files used by the example....

bonjour , j'ai essayé de communiquer deux pca10028 en utilisant l'exemples " transmitter_pca10028 et receive_pca10028 " mais l'experience a echoué je sais pas pourquoi sachant que j'utilise deux BLE Nano dans cette experience. quelqu'un peut m'aider svp. merci d'avance ...

![image description](/attachment/dc57ca43f53a74474c385b5a31d420a7)Hi,guys In my project,I intend to generate 4 channels pwm,using 8 channel PPI,timer1,timer2. As below, the timer initializing and timer interrup handler code: static void timer_init(void) {![image description](/attachment/47d469148082cd8a53c00be90b6dff48) /* Start 16 MHz crystal oscillator */ NRF_CLOCK->EVENTS_HFCLKSTARTED = 0; NRF_CLOCK->TASKS_HFCLKSTART = 1; /* Wait for the external oscillator to start up */ while (NRF_CLOCK->EVE...

I am working on getting FreeRTOS working on the nRFDK PCA10028 without the soft device running at the moment. I used this work as my reference https://github.com/nocko/FreeRTOS8.0.1-nrf51-softdevice.When I have 2 task running without issue but when I halt the debugger and resume the task don't run. The RTC clock counter seems to have passed by the compare register as the system is halted. Is this common, is there a way to ensure that the clock stops when the debugger halts?Thanks,Darren...
