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...

Hello,
I would like to use app timer based on RTC1 in order to wake up the MCU every X sec. The app timer seems to work correctly when the MCU is working. I use the following...
Hi everyone,
We are developing with Nrf52 and it's been a bit of a manual process for us to test our code, we use makefile so we were able to create a clunky system to...
I might need to use SPI and I2C simultaneously in a design, due to the fact that one of the components is only available in an I2C version.
Can the nRF52840 be configured...
Hi
We exposed NFC Type 2 functionality in our nrf52 a while back. Then the NFC SDK got refactored and I had to refactor my code to suite.
Now I am trying to enhance my...
Hi,
We would like to protect our product from people accessing the device via J-Link. We build our application with FreeRTOS. Can we follow this to set it before I start...
