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...
Hello,
very simple question:

Hello all,
I have a question about the SAADC of nRF52832.
Now I use the SAADC to measure the some external sensor voltage and the internal VDD voltage.
The sensor connection...
Hello, Excuse me! I used the LFRC,the calibration interval of which is 8s, in my application on NRF52832. In order to measure the power consumption,I want to know the duartion...
Hi,
As well know, nRF52832 can use "16Mhz base-clock to output PWM signal, and it is very simple to create 4Mhz, 2Mhz, 1MHz signal output,
But, If I want to output a...
I'm trying to get a stripped down, simple LED blinking sample to work (like blinky) when building with GCC however main() is never called. I'm guessing I'm either using the...
I'm trying to take a project we had working with only an application, no softdevice or bootloader, and add a bootloader and softdevice, with the application still not requiring...
I am working on nrf5_SDK_for_Mesh_v2.2.0 with nRF5_SDK_15.0.0 and softdevice 6.0.0. I run code on PCA10040 dev boards. I am trying use a timer to send onoff message from a...
Hi Nordic,
Does FDS affect PPI ADC acquisition when writing data? The test found that once the FDS is written to the data, the ADC data returned by the PPI ADC is fixed...
Hello Nordic experts,
I am working with nRF5_SDK_15.2.0_9412b96 SDK.
In example nRF5_SDK_15.2.0_9412b96/examples/ble_peripheral/ble_app_hrs_freertos/main.c I have at line...
Hi all,
The setup that I am aiming for has a number of nodes, which will send the IMU data to a central base station. The communication is achieved using a bunch of nRF24L01...
I keep getting stuck in the TIMER1_IRQHandler function.
When I debug the code, I get to line 20 (exiting interrupt function scope) and then the assembly code hits a nop...
Hello!
I have developed a BLE HID (HOGP) device in Nordic SDK 15.0.0 starting from an example project: ble_app_hids_keyboard .
The HID device that I have developed however...
We have a setup where we want to measure the current consumption of a battery-powered device:
The batteries are soldered to the device, and cannot be removed.
We can...
