Hello,
I have an NRF51822 (redbealab ble nano) that I would like to use to count pulses in very low power mode.
Pulses are asynchronous
The rate of pulses can...
Hi
I'm attempting to read a PT-100 sensor value that is part of a voltage divider using a nRF52.
Both the reference resistor and the PT-100 is sampled while the voltage...
Hi
I have been searching the forums, but were not able to find an answer to my question.
I'm trying to sample 4 analog inputs on the nRF51-DK using the ADC hal. (SDK10...
Hi
I have been trying to get two NRF24L01 chips communicate with each other since a week now, without much success. All what I can find on the net is Arduino examples using...
Hi
I have done several projects with the nRF905. I know the device quite well. Normally I use the CD, AM and DR interrupt pins to determine the status of the device, my current...

Hello,
Could someone give me a hint with the following problem?
I am using two example projects (ble_app_uart_c, ble_app_hrs) to connect a central and a peripheral.
An...
Hi,
I have got new nRF52832 custom board. I am able to send AT commands and getting responses. After that i tired programming ble_app_uart Example and it stuck at ble_init_stack...
I take the TWI master example of nordic, and try to build I2C read API that can be use from otherr places.
The function look like this

Hello
I am trying to do BLE communication using BLENano2 (nRF52832) now.
Therefore, using SDK 15.0.0, we are writing a program with keil u5.
Since writing to the softdevice...
I am a bit confusing about this two mode settings. We plan to use MODE=BLE_2MBit on both TX and RX sides as it can give us about 2dBm sensitivity improvement on the RX side...
I need to transfer data from my ADC (analog to digital conv) on a custom made, nrf52 PCB to a mobile app via bluetooth. For this I integrated my working SPI data transfer...

Hi all,
I have an application where I have a mobile app that communicate with up to 20 BLE devices. The BLE devices are RGB LED lights with push buttons and a sensor. I...
Hi.
I'm trying to use nRF52 as TWI slave.
I am using Segger Embedded studio for the coding part and nRF52840 PDK.
I wanted to use TWI between the nRF52840 board and...
Hello Helper,
I am currently running ble_app_uart on 2-3 nRF52 dongles that acts as a node and ble_app_uart_c on nRF-52 DK that acts as a central. While establishing different...
hi:
App <lightblue or nrf connect> (ipone6) connect nrf52832 failed .But using Android won't cause this problem.
Here is the log that failed to connect lightblue...
Hello,
I am using my own board with the NRF52832 device.
I currently have a NRF DFU bootloader programmed and soft device. I used it to download my own App using the NRF...
Hello everyone, I am starting with the NRF52840 dongle. I intend to use it for a Uni project because I'm gonna use it later for work (new product). Since we're using STM32...
Hi everyone! I'm a beginner with BLE. I'm trying to test Eddystone beacon. I'm successfully run "ble_app_eddystone" example in NRF52 SDK, and I also successful connect to...
We are doing some rapid prototyping using PCA10040 boards. I have a bench-top setup with a PCA10040, and some sensors. We want to place our sensors on an Arduino shield, enclose...
