Hi,
I have two CPU in our product. (STM32F2 and Nordic nrf51422).
I use serialization function to link those two CPU(refer to ble_s110_serialization sample)
But I find...
I am making a device using the nrf52dk that takes data from 5 separate sensors and sends the data to a nrf52840 dongle. My trouble lies with the ADC data collection. When...
Hi Devzone. I have a PCA10056 that I'm using to set up for CI / HIL testing, using an external nRF52840 on another PCB.
The external SWD on P19 is working perfectly.

I have achieved bluetooth direction finding using nRF52833DK. I would like to do the same with a custom board. I have used the BM833 chip for doing this. I have attached the...
Dear Nordic,
We made an attempt to use the external flash in the LwM2M sample.
We tried to follow this: docs.nordicsemi.com/.../nrf9160_external_flash.html
As soon as...
Hi.
When working with certain nRF connect SDK versions 2.x.x (not sure which range) in visual studio code, the build terminal outputs relative file paths when showing warnings...
I am looking for some simple slave and master samples to run on my dk's nut cant find any. in the intermediate course there is the master slave talking with the sensor but...
When will the nRF9151 Hardware Design Guidelines document be available?
We are currently leveraging information in the nRF9161 Hardware Design Guidelines document in the...
I am building a nrf52840 custom board and testing the ble_app_blink_pca10056_s140 example from segger I have a 32MHz crystal and a 32.768khz crystal And I added the following...
I've got a custom board using an nRF52832. I'm using the P0.06/P0.08 as the TX/RX pins for UART comms, but don't need the P0.05/P0.07 pins for CTS/RTS. Is there anyway I can...
Hello. I am currently working on a Mesh Network using the Nordic Thingy53 board. As far as I understand, the Mesh protocol developed by Nordic already has encryption, obfuscation...
Hello,
In a project using the NRF52832. Softdevice SDK 19.1.0 and Segger IDE, I inizialize the BLE for having NUS and DFU services actives. I try to reproduce the code here...
Hi,
I would like to ask when using zephyr's k_timer it uses a clock from LFCLK, then it can be generated in the following three ways:
32.768 kHz RC oscillator (LFRC) 32...
Hello Team NordicSemi Q&A,

These seems like another dumb question. First off, I am aware that the nrf21540DK is the nrf52840 with the FEM tacked on the output.
I know I can select the nrf21530DK/nrf52840...
