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,

I'm using the SAADC of an nRF52832. I'd like to reduce the error of my measurements from the nominal +/-3%. I'm calling the NRF_SAADC_TASK_CALIBRATEOFFSET periodically to...
Hi,
I am trying to use nrfutil to generate my verification key.
However in the bootloader the key has this format
__ALIGN(4) const uint8_t pk[64] =

Hello,
I am trying to update my bootloader using DFU and I am running into a few issues. I have successfully flashed and tested my current bootloader on my board and everything...
I am using the nRF51822 in an application where I want to run the UART as fast as possible to communicate with a host processor. I have been able to get reliable communication...
I am trying to create a package file to use with the DFU on my design.
I followed the instructions for getting nrfutil latest version built and was able to generate a private...
I'm using an NRF8001 with an ATMEL ATMEGA 328P (the microcontroller from an Arduino). I need the microcontroller to go to sleep, but still allow the BLE chip to advertise...
Hi,
for development i am using gcc and makefile on osx.
I wanted to automate my makefile with the possibility to upload directly the hex file to my nrf52 devboard.
