1. I am trying to implement DFU(with USB&BLE) and USB Mass Storage with FAT FS filesystems on external QSPI flash. I am getting the following build errors- with SDK version...
SDK: nRF Connect SDK v3.0.2
DK: nRF54L15-DK
Sample: spi_flash
default:
mspi-max-frequency = < DT_FREQ_M ( 8 )>;
If I change it to 32, it will printf these...
Dear Nordic
I am programming with nrf52833,ncs v2.9.0 base on sample\peripheral_hid_keyboards
Peripheral side(nrf 52833) adverting as Scanner_CE42,and iphone connect to...
I have read info somewhere which said there is method to crack the protection just by setting UICR APPPROTECT register.
I want to know if Nordic has upgraded the protection...
Hello,
I'm looking for answers and some explanation for two main questions - is it possible to perform non-simultaneous multi-image FOTA over WiFi? Is it possible to support...
Hi,
Due to pcb constrain, we need to use single button mode with PG/RESET routed to SHPHLD. In this mode long press for reset in the datasheet but nothing is said about...
I found this website.

Hi, this is kind of a basic question.
So please forgive me if this is too easy...
This picture is from nRF51822_PS_3.1.pdf.
Also these pictures is from the...
I am trying to use a differential antenna with the NRF51422 and I do not want to misunderstand the datasheet. It says that the optimum differential impedance at 2.4 GHz seen...
If, how can I change the order of the descriptor? I would like to have the user_desc at first.
Most likely by changing their UUID but how to do that? I can't find any trace...
Hi every body,
i try to use 10 bit ADC resolution instead of 8 bit in the ble_uard_adc example, the problem is the ble_nus_send_string is configure to 8 bit, how can i...
Before I order the NRF51-DK I want to make sure, is it possible use it to program other nrf51822 modules? Can I use the Segger on board for flashing firmwares on other modules...
Hello,
Let me first try to describe my whole project I just started with today (Hardware just arrived).
I want to use the nRF51-DK as a central device to handle 4 peripherals...
I have these nrf51822 modules, bought them from this company Wireless Tag , it's a chinese company I guess but I just noticed that the modules only have a single 16 MHZ oscillator...
I using github code.
SDK is 7.0.1
SD : S110 7.1.0
Channel : 4 ch
Period : 20ms
Width : 1-2ms ( RC )
Sometimes the width operates at 18-19ms.
ex : PWM2 was...
I'm working with the ble_app_hrs_s110_with_dfu_pca10028 (nRF51 PCA10028) example and am wondering what will happen if I attempt to send more than one sample at a time. Will...
It looks like APP_TIMER_INIT changed in v8 of the SDK. I do NOT want to run the code for timer callbacks in the IRQ, I want to run in the background loop. How should I properly...
Hello,
Our application board uses two NRF24L01P and two microcontrollers, so we have total four quartz generators on board. To simplify things we would like to use a single...
I have a project which measures temperature and humidity. After measurement the data should be send trough BLE.
I have one service for the sensor and two characteristics...
