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...

I have two nRF24L01+, one as PTX and one as PRX.Both have following config: EN_RXADDR = ERX_P0, EN_AA = ENAA_P0, RF_CH = 100, RF_SETUP = 0x26, SETUP_RETR = 0xF0, SETUP_AW = 1, RX_ADDR_P0 = 0xAB 0xCD 0x00, TX_ADDR = 0xAB 0xCD 0x00, RX_PW_P0 = 8.All packets are received by PRX, but about 40% are marked by PTX as lost. If I change speed to 1Mbps, then missing ACK rate lowers to 10%....

How to find nrf.exe

Hi,everybody! When i install master control panel 3.10.0.14, i can't find nrf.exe in " C:\Program Files\Nordic Semiconductor\Master Control Panel\3.10.0.14\nrf ". Only nrfutil.exe. What should i do, thanks....

Hi, I've been using the nRF51 dev kit, and today it stopped mounting when I plug it in. It doesn't show up as MBED or BOOTLOADER.I use both Mac OS X and Windows, though all work in the past has been on my Mac.Nothing strange has happened since the last time I used the dev kit. It's just been sitting on my desk in its static bag.When I run nRFgo Studio on Windows, it says "Boards connected: No boards connected". Under Device Manager, "nRF5x Programming" is grayed out.When I open the HRM...
