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,
I am working on my hardware product having nRF-51422 chipset. I just came to know from forum post that
nRF-52 chips will get arduino IDE support as standalone. I want...
Hi!
I've been using PCA10028 for a long time and I had some bricking issues but I've managed to un-brick it with "nrfjprog --recover" and everything would work again. ...
I want to build nrftoolbox app in android studio. I downloaded the zip file from the github website and also the required dfu library. I unzipped both the files in a folder...
I've tried a trivial example (blinky-like, compiled by gcc using proper startup and ld scripts) on nRF52 devkit, but I always only get hard fault.
Debugging through the reset...
The nRF24L01 dataseet V2 (the most recent I think?) states (p.23) that the nRF24L01 can operate on frequencies from 2.400GHz to 2.525GHz . The channel steps are stated as...
I am completely confused by the nRF51 UART. I'm trying to port code originally written for an STM32 (another cortex chip). There, I define an interrupt, enable the RXRDY or...
Hi,
I need to have two different interrupt handler for one pin?
For LOTOHI one handler and for HITOLO another handler, how to do that?
Here is what i did until now...
Hello Nordic and fellow developers
While implementing bonding into an application based on S130 I found it necessary to test on the role of a given connection. Different...
I am getting device id of peripheral on central and then getting it displayed on hypertermianl hyperterminal using ble app multilink perihperal code with multilink central...
Hi Everyone,
I have what I hope is a simple questions. I am creating a piece of hardware that will act as the peripheral to a central iOS app in regards to a standard BLE...
Is there any construction available in the SDK, to achieve printing functions, with an undefined number of parameters ? The classic example :
#ifdef CONFIG_DEBUG
#define...
Hello,
I've ready the final S130 spefication and it states that the advertiser is started as early as possible and that i runs asynchronously to all other roles. Now I...
Calling app_sched_event_put() from the NRF_RADIO_CALLBACK_SIGNAL_TYPE_START signal handler causes a crash due to the CRITICAL_REGION_ENTER() call inside of app_sched_event_put...

I have a simple nRF51822 BLE application where a voltage is read by ADC periodically, and several values are sampled and averaged. However, from time to time, I get another...
Hello All ,
I am working on nrf51822 with sdk 7.1.0 and softdevice 7.1.0 .Earlier my ble connection was working very good with no disconnection anytime unless i disconnect...
Now I'm working with MCP 3.9.0.
When any device is connected, characteristic default values are not 0's. Can they be initialized in any way? It is a little bit annoying when...
