Hello.
I would like to develop FW for the nRF52832, using Eclipse IDE + ARM GCC + Segger JLink OB.
I've seen on the segger webpage that the nRF52832 is a Cortex M4 processor...
When using app_timer through scheduler, a break and go will overflow the event queue if a timer is a repeat timer. The effect is that it's not possible to debug.
To work...
I need to be able to actively set the value being incremented in the Timer2 register on the nrf52 (what I believe would be it's main register). It seems that this might be...
The errata for the nRF52 indicates higher consumption in managing timers and GPIOTE. Does the BSP for SDK11 follow recommended practice to deal with these errata can I ask...
Hi,
I am trying to understand the pstorage to record a log for temperature. In my code, I can call pstorage_init(), and clear a block but when I try to store some data...
I would like to source a compact BLE board to act as a lock controller developed with with a matching transceiver for use in a fob and an app.
It would toggle the pio and...
I have a SPI Master and a SPI Slave. The Master will randomly pull data over SPI from the Slave. The slave will randomly generate events that result in data to be sent to...
I am using SDK version 17.0.2. The example code uses SPI.
The following changes have been made to the pin settings.
Questions
1. Pin behavior is strange.

Hello, Support team.
Our boards do SPI communication to read sensor data.
Basically It works well. I checked that It operates more than 5 hours.
But only one board...
Hi,
I have the following initialization for advertising:
The name consists of an acronym od three letters and a underscore e,g, XXX_ and a six digit ID. Like XXX_12E124...
Hi,
Is it possible to add four pairs of resistors between the debug signal lines and the connector as shown in the figure below.
Would such a connection not impair the...
The Google Fast Pair Service has recently been included in a number of Bluetooth peripherals (Headphones, fitness trackers, etc.) and has been getting rave reviews.
Has...
I am able to download simple blinky program on my custom board. It is working fine. Custom board is interfaced with nRF52-DK through P19. I am using embedded studio as IDE...
Hi, on nRF5340 I want to capture accurate timing of external events. I need a kind of real-time capture module to read the time period of a pulse train generated by a rotating...
Have a few questions about ble_app_uart example.
From the way I see it, it sets uart_event_handle as the callback, and every time there's an "event" that takes place...
Hello All,
Method 1: I am writing a test application to read the ADC data at a specific intervals(10 samples for every 5ms interval for every 50sec). I am using blocking...
Hi,
We are implementing a synchronous light flashing of multiple devices, so:
1) Can we get a millisecond level (< 10ms) time synchronization by parsing the Link Layer...
Hi, all
I added a scanning module to the example 'ble_app_uart.c', so each one works well.
What I want to do is advertising and connect at the same time while connected...
What is the best practise for multichannel SAADC conversion in ultra low power devices? For example I have to measured 4 channel in interval 250ms. Below what I try:

Hi, Dear Nordic & all:
when I run the ble_app_hids_keyboard example in nrf52820(SDK17.0.2), I meet a question:
1、Frist I use my iphone connect ble device and pair success...
Dear Nordic:
so I want to know In nRF52 serials chips, How much HFCLK CONTROLLER ppm is the frequency offset distribution and production FT control range? Do you have any...
