In December we published a video showing a long range test with the newly released nRF52840 chip. The video showed that the nRF52840 had excellent range, and is fully compatible with the new Long Range feature of the just released Bluetooth 5 specification. This blogpost will go into more details about how this test was done. Below is the video for those that have not seen it yet.The setup consisted of two nRF52840 Preview Development kits, one transmitter (TX) and one receiver (RX). Both kits were connec...

Program the boards Connect all the boards to the PC cd to <install_directory>nRF51_ble_broadcast_mesh_0.8.7\nRF51\bootloader Open a command window in that directory Run .\pc-util\for_loop_batch_nRF52 this will program all the boards connected to the PC. Take 4 boards off and connect to a USB hub connected to a Charger Determine the COM port of the remaining board by going to Device Manager>Ports (COM & LPT)  Use DFU over the air to program the boards. CD to <install_director...

The nRF52832 and nRF52840 devices have a built-in NFC radio which can be used for exposing data as a dynamic NFC tag (a tag with configurable data). This can be used as a standard tag type for storing a web link or a text, to launch apps on smartphones and tablets as well as for simple and secure BLE pairing (read more here). All these features are provided by the Type 2 Tag library in the nRF5 SDK.Starting from version 12.2 of the nRF5 SDK, we expanded the NFC software to support even more features. The ...

I'm pretty new with microcontrollers and SPI.I connected fisically an nrf51822 microcontroller to an external SPI flash memory.I connected MISO MOSI ports to some random P.xx pins of the microcontroller.I've trouble to understand to which pins should I connect the Clock . I've seen a CLK port on the microcontroller schema so i connected it to it.But now i've troubles to understand what this code should look like: spi_config.SPI_Pin_SCK = SPIM0_SCK_PIN; spi_config.SPI_Pin_SS = SPIM0_SS_PIN;To which pin sho...

## Setting up an example of the problemAs I promised in [this thread][1], I have been testing out the ADC on the nRF51822 and trying to see how quickly I can sample per minute vs how many interrupts I trigger per minute. This is because the nRF51288 is the chipset that I have available and it does not have the SAADC features that the nRF52 series has.I have submitted the code to BitBucket so that I can keep track of my changes and I have created this branch to expose the problem: [robertmassaioli/ble_app_...

We would like to review the following impedance matching circuit:![image description](/attachment/3fa4d35546ea8ca5e828da83c5b8f547)...
