I am trying to find out the part number of the antenna (I assume it is a PCB antenna) used in the nRF51 DK ( www.nordicsemi.com/.../nRF51-DK) . I found a lot of similar questions...
Hi.
I am using the NRF52 Development board, on Keil uVision, to implement a C program that uses Dynamic Structs. The Structs re-size themselves ( by increasing their capacity...
Hello,
I have an NRF51822 (redbealab ble nano) that I would like to use to count pulses in very low power mode.
Pulses are asynchronous
The rate of pulses can...
Hi
I'm attempting to read a PT-100 sensor value that is part of a voltage divider using a nRF52.
Both the reference resistor and the PT-100 is sampled while the voltage...
Hi
I have been searching the forums, but were not able to find an answer to my question.
I'm trying to sample 4 analog inputs on the nRF51-DK using the ADC hal. (SDK10...
Hi
I have been trying to get two NRF24L01 chips communicate with each other since a week now, without much success. All what I can find on the net is Arduino examples using...
Hi
I have done several projects with the nRF905. I know the device quite well. Normally I use the CD, AM and DR interrupt pins to determine the status of the device, my current...
I tried this using the ram_retention example from the SDK (nRF5_SDK_15.3.0). The example (Ram Retention) still seems to work if the lines concerning NRF_POWER->RAMON and NRF_POWER...
Hi,
our appliction need to using I2S worked at 96kHz sampling, and i find two parameters , MCK and the CONFIG.RATIO,but when i use this formulation:
LRCK = MCK /CONFIG...
Hello,
I think about connecting two central devices (nRF's 52840) using one common antenna. One device will be only RX and will scan for a advertisements, second will manage...
Hi, I am from China. My company made a BLE module with chip nRF52810. Recently , I coded a program for it by SDK12, based on ble_app_uart example. I modified the corresponding...

Hi,
We are currently going to try and implement FOTA/DFU with an nRF52840 controller and an nrf52832 peripheral. Is there any example for how this can be accomplished...
Hi,
I currently have a nRF52840DK pre-programmed with the DFU over BLE, but with the debug version. I am unable to physically get to the device, if I wish to perform a...
Hello,
We are using the SPIS on the nRF52832. We are seeing a higher than expected consumption when it's enabled and not used.
I measure around 7uA extra when enabling...
Hi:
I test the system off mode, I attached a micro vibration sensor. Pulse generated when shaking as follow.
the button config is BSP example default(toggle) , i try to...
Hi,
I am testing the blue_app_uart example and I want to send data
from my smartphone uart terminal app,back to the nRF52840 DK,
Nothing is being received by the segger...
In the latest Mesh SDK, nodes are subscribed to a GROUP address. In previous versions - 2.0.0 I believe - you could also send to a predetermined node.
I am trying to figure...
Hi I am reviewing the nRF52840-DK hardware documentation to make boards with good antenna performance.
Q1. I have divided it into three areas as shown below. Is my understanding...
Hi,
I have been trying to use Keil MDK's Middleware File System with my application. However, when I try to set the Software Component under Manage Run-Time Environment...
