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 made this project to try to create RSC service on arduino

Hello guys,
I am currently looking at the recommended schematic QFN48 with internal LDO setup and I have a few questions (sorry, if they are silly, I am a newbie).

Hi, I'm working on an extremely space-tight design and need some clarifications. It is an nRF52832 QFAA chip with a Johanson 2450AT18B100 chip antenna.
Up to this point...
Hi,
I would like to use higher dBi antenna instead of the DK pcb antenna. Can I say the pi-network before J1 (measurement point) probe is 50ohm? Hence I can just remove...
I am trying to control another BLE device with nRF52xx. For controlling the device I need a terminal for connecting, disconnecting and switching on & off a sensor. I have...
I am using NRF52DK and trying to debug an SPI transfer, using SEGGER_RTT.h to print. However, printing of the logs are not consistent. Some debug lines do no appear in the...
Hello,
The only semi-official information that I can find regarding the differences between PCA10040 1.1.0 and 1.1.1 DK boards is this post . It suggests that there are...
I recently ordered two NRF52840-PDK and a Segger J-Link Base to program/debug the boards.
Then I just read that the development kit have a J-Link OB included, or I could...
Hi.
I wonder that how to setting continuous modulated output mode for nRF24L01P.
I see Appendix C - Constant carrier wave output for testing in datasheet.
But there is...
I see in the SDK 13.0.0 release notes that the NFC type 4 library was updated to "production ready", but I couldn't find a summary of the changes made to the NFC Type 4 library...
So... As I understand it, micro-ECC is a free library that lets you create an ECC private key for signing the SecureDFU that Nordic is using.
The nrf52840 has Cryptocell...
I've put on the stock dfu/bootloader_secure on the nrf52 DK.
I've then create a distribution ZIP and upload a blinky app to the DK. That worked fine.
Then I compiled...
Hi,
I have problem with DFU for 51822xxAB witch has 128kB flash.
I use dual bank bootloader for nrf51422xxAC witch has 256kB flash memory within nrf51822xxAB.
Ofcourse...
I know this might be a dumb question to you all, I am first time doing this sort of work
How to connect Jlink to NRF52? I need to flash a custom built BLE board with new...
