Hi Nordic,
I've built a ble app with a custom protocol, but am struggling with storing bonds, when running under freeRtos.
What I see:
central app crashes (hardfault...
Hello All,
I am new to this forum, I have been using nRF51822 for a while, and its a great little BLE chip. I am usinga BLE keyboard to send a key to iphone and I captured...
I WANT COMMUNICATION BETWEEN A NRF51422 AND NRF528321 BOARDS, IN WHICH IN NRF51422 BOARD I WILL MEASURE PWM COUNT(IT IS PHERIPHERAL) AND SEND IT TO NRF528321 BOARD WHICH IS...
Hi,
I've been working on a way to detect and prevent replay attacks when beacons are used for sensor data. This is mostly used for home automation sensors, where I have BLE...
Hi,
For our current application we have migrated from SDK 13 to SDK 14. We are using RTOS to handle the functionalities of our application. We replaced our own task for handling...

Hello,
I am trying to do communication with external module using UART0. But when I connect pin P0.28 (RX of UART0) to external module to receive the data, there is no data...
Hello,
I am working with SPI on the Nordic nrf9160. I am currently on the DK.
The board I need to interface through SPI works at 25MHz (minimal frequency) and I would...
Hi everyone,
I know that I can configure the resolution of app_timer by adjusting the prescaler form sdk_config.h
However, what is the practical purpose of prescaler...
Hello,

Hi, I want to write 510 bytes of data to my BLE Characteristics, so I set parameters ble_gatts_attr_t max_len as 510 and its variable length attribute. Also I set NRF_SDH_BLE_GATT_MAX_MTU_SIZE...
Hello,
I just bought a new nRF5340 PDK and wanted to learn it a little bit. I searched on the internet and found very useful information about nRF53 architecture.
But...
Hi,
We have a question regarding a custom implementation of flow control for nrf52840 using SDK16 w/ SoftDevice 7.0.1. Currently, our sensor's primary micro transfers data...
A newbie here. I am studying the simple_timer application in the nRF5_SDK_17.0.0_9d13099 library.
The sample application sets the clock frequency to the timer at 16MHz....
Looking around to develop hardware/software using the RAK4600 module!
RAK4600 (lora Node) uses Lora as its main way to communicate with my Lora server (normal flow).
Consider...
Hello,
I would like to switch on a led of a nrf52840 dongle by pressing the buton of another dongle. I don't know which example to use from SDK 17.0.2 to make a master/slave...

Hi,
I tried to implement the UART in my code, based on the UART example code. Just as in the example, I first define the struct with the pin numbers:
The pins in this...
I found there was a example in "nRF5_SDK_15.2.0_9412b96\examples\dfu\secure_bootloader\pca10056_uart\arm5_no_packs" .
