This article baed on "pca10040", nRF52832example code path "examples/ble_peripheral/ble_app_uart"IMPORTANT!!!!board config file of this example located in "components/boards/pca10040.h"and uart pin defined in this file, like this:define RX_PIN_NUMBER 8define TX_PIN_NUMBER 6So, the KEY point of this example is uart character goes through PIN#8 an PIN#6if you don't know where are they, see schematic of you boardI spend whole night to figure out why I can't see any...

"ELIO" is a Bluetooth module and smartphone application that can drive motor(DC, Servo) and illuminate LEDs.This module mounts Nordic's nRF52832 and motor controller IC.Smartphone application can create/modify their own model using model-editor. The key point is No coding!!! Just plug & play. Plug DC motor, Servo motor and LED to ELIO and control. PWM channel is adopted and this can speed up from -100% ~ 100%. Model editorThere are so many models in real-world. Car, Tank, Boat ...Th...

How much is the nRF52840 USB DP/DM pins impedance.There is no info in datasheet .On the PDK board there are 39 ohm resistors connected in series with USB signals.Are they intended for impedance matching ?...

Howdy,I am having difficulties writing to NVRAM (reading appears to be fine and is reporting 0xFF's everwhere). I am using a rather old SDK and SoftDevice 110 (version 8) on an NRF51822 because I was modifying code in production.I am trying to save some calibration to NVRAM (my old code worked fine, but it no longer is and I can't find where the problem is). Unfortunately the erasing and saving does not appear to work. All of the Nordic SDK functions are returning NRF_SUCCESS; however I never get a call b...

Hi guys,I am using nrf51822 with SDK 11 and softdevice S130. I use Just Work bonding with Peer Manager. When I connect nrf51 with the Android phone run NRF Connect, the device will automatically bond to the nrf51 when I hit to the "enable notification" button of the authentication characteristic. However, in the IPhone NRF Connect, the IPhone automatically generate the question :"do you want to pair with this device" immediately when the IPhone connect to the nrf51 device. Is there any...
