It is good practice to prefix the includes from one's C libraries with a directory so that they are all part of the same 'include namespace'. Unfortunately the Nordic SDK...
Hi, is there an available developer in my tri-state area of Minnesota, N. Dakota, or S. Dakota? Please call me if you are available for a project for hire. The developer should...
I'm trying to design a very low power sensor that takes readings using ADC and SPI 200 times a second. I'm a bit worried by the current EasyDMA uses (1.1mA). As far as I can...
Hi, I am working on a project where I want to make one nrf51288 chip as central hub and connect that to a android phone and other salve nrf51288 .

Hi,
I have a code programming the nRF51422 development board to write to a Sharp Memory 96x96 pixel LCD screen using SPI.
Currently the code writes two numbers and a...
I've modified the ble_app_uart example by adding GPIOTE so that the transmitter sends a character to the receiver when a GPIO pin is toggled. This part is working well.

Hi,
from Keil uVision I need to debug/program nrf51822 in my application which uses 1.8 V. I guess nrf51 DK is not capable of doing this (it supports only 3 V targets). What...
Hi,
I have a reset issue when trying to set a delay greater or equal to 100 milliseconds using nrf_delay_ms(...). This only happens if I start my app timers (app_timer_start...
Hi,
I am trying to generate a 128Hz sine wave using the nrf_pwm library . First I tried this with SD110 enabled but ran into some problems that turned out to be a known...
Hi,
I'm going through the errata and a few of them look serious that the developer kit might be useless for some of us if we want to use it for any realistic testing (I...
I am trying to add a static passkey to my peripheral and protect from MITM. I tried the example nRF51-ble-app-uart-static-passkey but it doesn't seem to work correctly.

Hi,
I am new to nordic n51822, i have implemented adc and timer independently.
Now, what i want to do is read the adc values on a specific time when the timer overflows...
Received my nRF52 preview board yesterday and have been battling to get my S130 based nRF51 code running on it with the S132 soft device (the code is here: github.com/......

Hello,
I'm trying to get the new SDK up and running on my OSX machine. I would like to make the blinky example work on my PCA10003. So, I copied the blinky/pca10028 folder...

I have been able to generate the required frequency however I am observing...
Not a question but thought worth mentioning.

Hello,
I am working on an nRF51822 custom board application which is reading data from external sensor through TWI. It is based on the MPU6050 driver available in the SDK...
