Hi all,
I'm working on a Nordic-based system involving multiple nRF52-series chips exchanging high-rate sensor data over both radio and SPI links. The setup involves two...
Howdy!
I am attempting to develop a system using an nRF52840 and an ADS131M04EVM (ADC). Our application requires us to collect data at a high sampling rate (>= 16k SPS...
I have a nrf9160 DK but when upload SLM application to it i can not send AT commands to it over it's usb port but in asset tracker application it works i want to modify SLM...
Finally we got our prototype boards and proof of concept firmware code done and we are a bit stuck on the average power consumption over time for the entire sensor that is...
We are implementing a Joiner device using OpenThread on the nRF5340 (with Zephyr, NCS v3.5.99-ncs1-4). After successfully joining the Commissioner's network ("Join success...
Hi,
I have integrated Neuton’s “Transport Type Detection” pre-trained model into my firmware, running on a nRF52840dk. For collecting 9-axis IMU data, I’m using the ST X...
Hello Nordic Team
I am using SDK 3.0.1 with a nRF52DK to develop a firmware that can be switched from BLE mode to GAZELL mode and vice versa over a command sent via UART...
Dear Nordic,
I am having some apparent delays in the time that passes from the pressing of a button, and the execution of the ISR that this button triggers. I am using...
Hi， Nordic
I checked DFU operation, found DFU work in bootload mode.
I want to know below operation is OK or not. Plz help me check:

Hi, I use the PCA10040 v1.1.
This is an example of a PCB stack-up.
My questions are,
In the case of PCA10040, which is 4 layered, what are the values of...
Hi,
I am writing a firmware for one of my custom boards which use GPIOTE to detect interrupt for 3 GPIOs inputs (P0.03, P0.06 and P0.09, both with internal pull-ups) and...
Hello,
I'm trying to write my ADC samples over spi on a sd card (Using SAADC like in the sdk 12 example with PPI and using fatfs like in the example in the sdk).
I open...
I have been using the pc-ble-driver Python bindings to implement a peripheral. I have extended BLEDriver to support sd_ble_gatts_* the functions. I now have a working peripheral...
Hi All,
I am struggling with this question from many days. Does the SPI transmit or receive operation in SPI master code uses DMA? While using SAADC DMA I have specified...
I'm using an app timer to blink an LED while in the bootloader.
Initially I was configuring an app timer when the bootloader started up and never stopped it, assuming the...
After failing in replacing a Cortex M4 for a NRF52832 I'm studying the possibility of using a NRF51822 as a BLE controller, used by my Cortex M4 MCU.
As I saw there is...
Hello
Please tell me about sd_ble_gatts_value_get ().
Before execution, handle is 0x11, but after execution it will be 0x00.
Is this an abnormal thing?
In our earlier projects with nRF51 and SDK 8 we used to have bluetooth device names of length 13 or 14 characters. However, when using nRF52 and SDK 12 I noticed that the...

Hello dear Nordic team,
we want to implement a white list to our central device in the production process. Bonding while producing is not an option for us.
Therefore...
We are having a project where temperature values will update whenever the temperature changes ,So I'm writing code like this
