Here is an example of a hardware setup to measure the voltage on a Lithium battery with a voltage divider on nRF52. The Lithium battery typically has a voltage range of 2.7 - 4.2 V and we (Nordic) recommend that you divide the battery voltage with two resistors. To reduce the leakage current through the voltage divider to the minimum, we want the total resistance to be as high as possible. Therefore, we choose R1 to be 800 KΩ. This is the maximum source resistance we can have and will require an acquisit...

 This series of posts will describe a new toy here at Nordic: The nRF Hexapod. The post will be divided in multiple parts, this part describing the project in general and the hardware that is required. All parts of this project is open source so you can make one yourself.The hexapod is built to show the power of nRF52. Using hardware PWM we can control up to 20 servos simultaneously, 12 using the PWM peripheral and 8 using a combination of TIMER, PPI and GPIOTE. This project also shows how a single c...

Sometimes we look for what will be the best demo for BLE operation between mobile device and peer device. Recently Blinky is one of perfect application, but I suggest one more interesting example between mobile game based on Android and nRF51-DK or nRF52-DK as a controller. Environment You may know Digital Bird already introduced in our Github, which was created as a part of BBC Make it Digital program with microbit. So this will be a nice game to operate with DK. https://github.com/NordicSemicon...

Hi, I am a new programmer to the NRF51 and I was wondering if someone would look at my code. I am trying to program the NRF51 to take ADC samples at a frequency of 1 kHz. My code also doesn't seem to produce any values when I run it on putty.Thanks. #include "RTE_Components.h" // Component selection #include #include #include "nrf_adc.h" #include "nrf.h" #include "nrf_gpio.h" #include "nordic_common.h" #include "nrf_delay.h" #include "app_er...

Hi all,I am using ble mesh code for synchronizing leds in mesh network. I need mesh part, but itshould not integrated with version. So i can able change state of led, according to my wish. Can any one tell me how do simple mesh code without using version, fifo etc. So that if a device send data it should be received by all other connected devices. But each devices should be able to act as master and slave.I tried with doing some alteration ble mesh code to remove version part, but it is did't work.Please ...

Dear Nordic.I want to connect multi devices(phones) to nrf51822 DK Board through BLE simultaneouslyis it possible?please check image(concept)![image description](/attachment/62c738d9680373285cee5d57b78d762c)...
