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. ...

Is it possible to generate useful documentation from the provided .dox file ? If I run doxygen.exe ble_api.dox I get some Latex and HTML output but looks incomplete bacause of missing sequence charts.I expect something of similar quality to : http://developer.nordicsemi.com/nRF51_SDK/doc/7.2.0/s110/html/index.htmlThanks !...

There is a GitHub example:[https://github.com/NordicSemiconductor/nrf51-dfu-ble-S130](https://github.com/NordicSemiconductor/nrf51-dfu-ble-S130)It states that the SDK 6.1 is required. Will it work with the 7.2 SDK using the s130 0.9 alpha soft device? Is there any document stating what to modify to make it work? Probably not, but figured to ask......

Hi Nordic Devs,For my project, I am looking for couple of tactile SPST (Single Pole Single Throw) switches like this [one](http://www.digikey.com/scripts/DkSearch/dksus.dll?Detail&itemSeq=167040815&uq=635608034532045024&CSRT=2469458049854407358). Would appreciate any alternatives that are cost effective. The usage by the end-user is going to be super low and so spending more than a buck per switch is not economical...Thanks in Advance,Ravi...
