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....

Hi all, I met one strange thing on SPI interrupt: when 51822 advertising, the SPI write and read works well; But, when CONNECTED, with BLE_GAP_EVT_CONNECTED event occured, the SPI does NOT give out the interrupt, spi_master_event_handler() not trig. The SPI IRQ priority is LOW and make this result happen. While set to HIGH, it works well, too. So, I want to know, whether the radio hold on the SPI interrupt so that app could not get it correct? Any influence with this priority change from LOW to HIGH?Thank...

Hi,Is it possible to use two LPCOMPs simultaneously?I would like to use analog channel 6 and 5 and if I register a RESULT Above on channel 6 it should start a software timer, if it register a RESULT Above on channel 5 it should start another software timer. Is this possible?...
