BLE and ANT development kit
Nordic Semiconductor offers the nRF51 series for BLE and/or ANT wireless connectivity. The nRF51 (nRF51422 or nRF51822) is a System on Chip, which means it has internal microcontroller to perform various operations. There...
I am investigating Master Emulator API and found something interesting that can help you program your device through BLE DFU in Keil. This method calls the python script used in MCP. If you can use MCP DFU to program your device, it will also works f...

I connected the programming header as described in "nRF6930_Beacon_Ref_Design_UG_v1.0.pdf" 5.5.4 Programming interface. I was trying to program Beacon Kit but failed many times then I compared it with schematic of of Beacon Kit. I found out...
Hi,
I have written SD & SDHC card routine for reading, writing and erasing data from SD card. It used the hardware SPI of nRF51822.
NOTE:
1)Define the PINs of SD card first before initialing.
2)Define MOSI, MISO and SCK pins only, define the ...
There are several types of write operations, write request with authorization, write request without authorization and write command. You can see message sequence charts for those messages here and here.
Write command is a write without acknowledgem...
Here is an example of a hardware setup to measure the voltage on a Lithium battery with a voltage divider and a connected capacitor. The Lithium battery typically has a voltage range of 2.7 - 4.2 V and we (Nordic) recommend that you divide the batter...
I've put up on Sourceforge, a Mac OSX application which interfaces with the Nordic BTLE sniffer software and has some of the functionality of the Windows application Nordic ships with that software package. Features include
