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. ...

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 ...

Which SOC I need

Am trying to setup a module where I need to send the Serial port ( say from printer/peripheral COM)to a BLE Peripheral/Central Module. Not sure which SOC or combination of them would help me achieve.New in the domain so would appreciate help with any details...

I've gotten the experimental_ble_app_s130_example_c_pca10028 (BLE Dual role application) to work with my nRF51-DK (modified for my needs). It's an nrF51422 chipset.I want top program it on the nRF51822-BEACON with this code. I've done this with J-Link..(s130 0.9 too). It programs and runs...but I'm obviously missing something because it never catches an event when I'm scanning.I've disabled the uart in the example too, and made sure the buttons map correctly.What other hardware changes am I missing? Any h...
