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...

Hello,
I am working with the nRF DK trying to read a sensor over I2C. I wrote some code in Keil uVision and I finally could read the sensor. The problem now is, for some...
I encountered a strange problem system reset. My application runs on iOS or android. My device was connected by iPhone 6 plus(128G) with iOS 8.1.2. ANCS was turned on. I have...
Hello Everyone

Hi,
So am new to all this BLE stuff, I have been using the nRF24L01 modules but want to move to the BLE variant, nRF51822.
I am these days figuring out the toolchain...
Hi,
I am developing on a nrf51822 based board using s110 softdevice v. 6.0.0.
In my program I need to change the bluetooth GAP device name in runtime
during connection...
Hi,
I compiled the nrf_heart_rate_collector. Apparently, this program only works once, between each run, "remote device" and USB dongle has to be resetted (unplugged from...
Hi, I'm testing the beacon example
(ble_app_beacon, Beacon Transmitter Sample Application ) with my custom board.
I use IAR 7.1 for ARM, Softdevice S110 ver 7.1, and...
Hi ,
I am trying to set up event using GPIOTE. I want to implement reading of sensor data and sending over BLE when an interrupt is generated due to activity on a particular...

Hello,
I try to add the Device Name to the ble_app_beacon example but it does not work.
First, define the Name:
#define DEVICE_NAME "MyBeacon"
Next, add GAP Pararameters...
First, many thanks for the great DFU recipe in the latest SDK!
I've ported OTA DFU to the IAR tool chain for both s110 and s310. I can flip back and forth between the two...
Hi,
I'm using IAR ARM Embedded Workbench (v7.20) to build my Nordic applications. Recently I enabled optimizations (in Project Options: C/C++ Compiler:Optimizations: Level...
