When designing a PCB with nRF51, nRF51822 or nRF51422, there are some rules that should be followed in order to get a good working radio/system, with a maximized range.General rule The RF part of the schematic and layout should be a copy of our reference design. It means that not only the component values, but also the geometry, relative placement of the components with respect to each other, and the lengths of the transmission lines should be the same as in our reference design. The reference design for ...

When using nRF8001 with an Arduino board, Atmel Studio is a good free tool to use for development of your firmware. The following video shows a procedure in Atmel Studio in order to enable debugging of Arduino code. It was created with Atmel Studio 6.1 and Visual Micro (Arduino plugin for Atmel Studio)...

Hi, guys. nRF51 IoT SDK is needed Raspberry Pi, so I make the VMware Player Image for Ubuntu 14.04.1 LTS 64bit(linux kernel update to 3.18.3). Even if don’t have Raspberry Pi, can use the 6lowpan!! And it’s easy to develop the linux 6lowpan kernel module by using the VM linux.VM Linux image and "How to" is my website, http://www.hirotakaster.com/weblog/6lowpan-ubuntu-vm-image/Glad I could be of someone help. ...

After I uploaded hex and dat file which is compiled from sample beacon source code in SDK to nRF51822 Beacon Kit via nRF master control panel app, I got Upload failed GATT ERROR 113 message and LED doesn't blink anymore.After that,I try to connect device again but connect button in master control panel turn to gray color. And when I try to connect it again, it still got GATT error and cannot run DFU function.However, nRF beacon app still found it normally. but cannot DFU like master control panel.What's h...
