It is exciting to see that in the release of Android Nougat, in addition to 72 new emojis, support for Bluetooth pairing with NFC using the out-of-band (OOB) method is included. By utilizing NFC pairing on Android Nougat, you can avoid the need to type in a passkey on your product, and still perform a secure pairing. And it is so simple that your grandma can do it :).The nRF52832 have a built-in NFC radio (dynamic NFC Tag). So the additional cost to enable NFC pairing to your product is very low. In fact,...

Hey!Wanted to tell you about this free J-Link upgrade for the BBC micro:bit.With the firmware upgrade your micro:bit DAPLink will be transformed into a J-Link OB (on board), while still maintaining the Drag and Drop capabilities that developers currently use with the online tools. So what do you need to do the upgrade? A micro:bit board, USB cable, the latest J-Link software installed, the upgrade HEX file containing the upgrade firmware.It's really easy to do the upgrade, just have to put the micro:...

Hey!We received 20pcs of a developer edition of the Arduino Primo from Arduino SRL, and we would like to share those with the best and most committed developers on Devzone, before they go on sale! Have you heard about the Arduino Primo board? It is a new maker platform from Arduino SRL targeting the IoT and it is based around the nRF52832! The nRF52832 is the main MCU and provides Bluetooth and NFC connectivity. The Arduino Primo also includes WiFi connectivity. If you want an Arduino Primo board and...

For conventional Bluetooth, if two devices are connected, we can send and receive text/bytes to and from each other. It is generic since the two devices can be from different vendor.For BLE, if we run nRF UART application on one device, the other one must also run the same application so that we can send and receive from each other. Is there a generic UART service defined in BLE? If no, why is that?...

Hi All,Another question for those out there much smarter than myself...We're developing an application using nrf52, sdk11 and softdevice s132 2.0.0 and have been using DFU single bank to successfully update the application OTA. Recently, we've made some changes to enable the use of easyDMA with the SPI master, which broke the previously working OTA updates. At a high level, we're using NRF_DRV_TIMER_INSTANCE(1) task to toggle an external CS pin and trigger a SPI transaction event every 1ms, to draw a line...

Hi,I want to communicate with other chip on UART.the chip on other end requires AT(CR,LF) command to start communication over UART.UART is setup correctly, but it reset the NRF51 chipfollowing is snippet of my code for sending data over UARTuint8_t p_data[4] = {0x41, 0x54, 0x0d, 0x0a};for (uint8_t i=0; iIt creates problem only when I try to put 0x0a(new line).otherwise it works ok.Is there anything I can try to resolve this ???...
