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!!

Hi, all!I am rencently studying ota,and that is what I have done: 1. Program softdevice 6.0 into my nrf51822 chip. 2. Program bootloader(version in SDK5.2) into my nrf51822 chip. 3. Use Nrf_TooBox app to upload an application into my nrf51822 chip by means of OTA.So far the OTA is finished.But I got the further question: If the application I upload into my chip is a normal application without the function of DFU(like ble_app_hrs), how could the chip be able to **go back to the bootloader again** and then ...
