We have been evaluating the nRF5340 and nRF7002 for use in a new product and we are currently looking at our Wi-Fi FOTA options. For reference, we are using an nRF7002 DK...
Hi Nordic team,
We are developing two types of devices based on the Zephyr examples:
periodic_adv_rsp
periodic_sync_rsp
Our design uses the following...
Hello,
I've a battery based device that uses a buck/boost to efficiently use entire battery voltage range (4.2-3.0) . This component have a low quiescent current between...
Good afternoon! As the NRF7002 takes about 400ms to start up from shutdown, we would like to use the very low power deep sleep function for quick startup. Unfortunately, due...

Hi,
I would like to know the difference between the nRF52840-QIAA & nRF52840-QIAA -R7.
What is the significance of R7 here. Not able to find it in any conclusion ...
Hi, I'm working with the DWM3001CDK (nRF52833 + DW3110) and currently using SPI to interface with the DW3110 for UWB communication.
I'm trying to use a second UART to communicate...
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...
Hello,
what do I need to pay attention to calculate the consumption of nrf51822 in low power mode (sleep).
I make this simple program :
