Hi.
I am using the NRF52 Development board, on Keil uVision, to implement a C program that uses Dynamic Structs. The Structs re-size themselves ( by increasing their capacity...
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...
i made this project to try to create RSC service on arduino

Hello,
I want to implement a single bank ble dfu bootloader for nrf51822_QFAC. I already read most of the threads regarding this topic here in the DevZone. But now I`m...
I am developing some application and I have decided to use Device Addresses to distinguish between devices. I have read device addresses of 2 chips (I have read addresses...
Hi,
I am working with Gazell device and host example code from the Keil pack installer, using the default the data rate of 2MBit, so per Nordic's documentation the timeslot...
I confused that I run a SDK 9.0.0 example ble_central_and_peripheral app_s130_demo on my nrf51 SDK. then use Android App MCP to scan Advertise data. it did not work.
but...
I'm faced with a curious problem.
The examples of nRF52 SDK 0.9.2 have linker sciprt like this:
/* Linker script to configure memory regions. */

Hi,
I bought two PCA10028 DK boards, try to start with the simple example with SoftDevice S110.
I download the application to the DK board by nRFgo Studio.
First...
Hello,
I bought 2 modules from this site:
www.elecfreaks.com/.../nrf24l01p-pa-lna-v31-rfm05-p-142.html
People are saying it's working great, but for me, there is something...
I had slightly modified a TWI example (using nrf_drv_twi) to work with one of my sensors; It's basically the same with a different function called to handle the received data...
I'm trying to test the throughput improvement of the S130 alpha softdevice vs S130 V1.
I notice a couple of changes in the API that I'm not sure how to handle:
First...
I've been using the ble_app_uart example with S130 on a nRF51 DK board. I wanted to add an interrupt with some GPIO pins. So I added GPIOTE interrupt handler but the compiler...
Hi all,
I want to ask you if it is possible to program nRF51822 chips (Cortex-M0) with J-Link OB assembled on nRF52 preview DK (Cortex-M4F).
I have some older boards with...
Hello,
I am working on pin interrupts and was able to handle with 1 pin interrupt. I used GPIOTE port interrupt. This is the code snippet for initialising:
NRF_GPIO...
I am trying to get my system with a hardware RTC generating periodic interrupts every 30 seconds to sleep between interrupts. I'll paste the code below, but here is the problem...
