Nordic's infocenter

The Infocenter – our new documentation portal - has now been up and running since June and contains all of our technical documentation. We saw the need for this because we wanted to make our complete library more visible, and since the documentation is now found in the one place navigation has become easier, with related content housed together under relevant topics. We’re also making content available in HTML (but, the core documentation is still available in PDF too) which means we can make minor up...

We recently announced that we now support “extended industrial temperature range” (-40 – 105C) on our nRF51822. The devices supporting -40 - 105C are the QFAA (QFN with 256kB flash and 16kB RAM) and the CEAA (WCSP with 256kB flash and 16kB RAM) versions of the nRF51822. There are a few limitations when using the nRF51822 up to 105C. The key limitations are: • Supply voltage range 1.9 V to 3.6 V (compared to 1.8 – 3.6V)• No 1 Mbps non-Bluetooth mode (Bluetooth low energy mode is supported)For t...

IntroductionUsing proprietary protocols can be an effective way of addressing shortcomings in BLE. When communicating between two nRF chips, one can for example use a different packet format or different symbol rate to improve throughput or increase range. Getting started with micro-ESB on nRF51 discusses the ESB protocol and the micro-ESB implementation specfically. Now we will look at how one can run a protocol such as ESB concurrently (interleaved) with BLE (or ANT) by leveraging the Timeslot feature o...

Hello, i have bought nRF51822 pcb module on Aliexpress (nRF51822 CEAA chip HWID 006A, 16Mhz crystal) and I'm trying to test it with SDK 6.1.0 and S110 v. 7.3.0 (as compatibility matrix recommends for revision 2 chips). It doesn't work. After flashing S110 softdevice and test program (ble_app_hrs example from 6.1.0 SDK compiled on OS X using gcc toolchain), and running it, after few instructions CPU seems to be stuck in some strange loop: J-Link>loadbin s110_nrf51822_7.3.0_softdevice.hex 0x0 Downloading...

Hi,I use nrf51822 with SDK8.1, S110 and gcc with Makefile. I want to use nrf_drv_twi in both my main “.c” file as well as a library “.c” file that is included in the build. So in my main file I have: #include //create TWI hardware object (see ../../../config/nrf_drv_config.h) const nrf_drv_twi_t twi = NRF_DRV_TWI_INSTANCE(0);... int main(void) { // Initialize. ... nrf_drv_twi_init(&twi,NULL,NULL); nrf_drv_twi_enable(&twi); ... }Then my main calls my library function, and the library functi...

NRF8001 Problems

Hi, I am trying to get the NRF8001 rev. C chip working with a Tiva Lauchpad (TM4C123GXL) board. I modified the original Arduino SDK for use with Energia. I am using the nrfToolbox app for Windows Phone 8.1.*Problem 1:*I got the UART example working with the launchpad. The problem is I can receive but not send data. When I try to send data from the Launchpad, I get a "ACI Evt Pipe Error: Pipe #:8 Pipe Error Code: 0x90" error. I noticed that when I delete the paired device from the phone, connect ...
