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...
Well not my best title. But I hope you can follow this explanation:
I added RTT to my project to replace UART. It works so far. But there is a strange behaviour...

I am trying to do OTA DFU on nRF51-DK from a BLE dongle (CSR 4.0) and gatttool from BlueZ. The image is compiled from blinky_s110_pca10028 example ( blinky_s110_pca10028.hex...
Hi
I want to program the S120 softdevice over an mbed HRM1017 ([link text] that uses nrf51822. I can program only with CMSIS-DAP or drag and drop over the drive. I am using...
Hello.
Initially when reading the Gazell documentation I didn't think it'd be a problem but now in Keil seeing this has introduced some doubt whether it's a thing:

Hello,
as I couldn't manage to get my SPI Measurement working flawlessly when called from inside a timer handler I tried to work around it by just setting a flag inside...
Hi,
I have a setup :
nRF51822_QFAC Chip Rev3
Softdevice: S110 V8.0.0
SDK: V8
Code hangs at sd_softdevice_enable(). Clock Source I am using is NRF_CLOCK_LFCLKSRC_XTAL_20_PPM...
Hello,
Has anyone managed to get the Nordic_UART software to pair in Windows 8.1?
The heartrate monitor software pairs fine. Using show bluetooth devices, I can see the...
Hi,
I have a PCA10028 board. When I connect it to a computer the LED LD5 doesn't turn on at all, and no new USB connection pops-up in my computer. But when I connect it...
I found this website.

Hi, this is kind of a basic question.
So please forgive me if this is too easy...
This picture is from nRF51822_PS_3.1.pdf.
Also these pictures is from the...
I am trying to use a differential antenna with the NRF51422 and I do not want to misunderstand the datasheet. It says that the optimum differential impedance at 2.4 GHz seen...
