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

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...
Hi,
I would like to use the nrf52 as my bluetooth end device, which inturn has to communicate with the Bluetooth IOT gateway like Rigado module or Nordic gateway APP(which...
Hi
I am using SDK 14.0.0 and soft device S130.
I am planning to add SPI functionality to BLE's sample code.
However, when moving to the next instruction after SPI data...
I am developing a beacon using nrf52810. This beacon will advertise iBeacon as well as Eddystone packets. And user should be able to configure some of the beacon paramters...
Hi Nordic,
I am using the example nrf_app_interactive with nrf52 DK. I am using it as a central while connecting to a peripheral. This peripheral has a lot custom services...
Hi,
I need implement a single Byte transaction on SPIM.

I want to use the RTC Tick Event as my system tick. But on both the RTC0 and RTC1 my programm freezes after about 8min.
It looks like the Tick interrupt is still served...
Hi,
We are currently at the process of manufacturing prototype boards, the manufacture cannot do pitch size under 0.25mm. They kept telling us that the chip's BGAs exceed...
Hi, I got a nrf51822 board and a st link v2 mini as shown below. I have been trying to connect the nrf51822 board so that i can upload code to the board by following this...
Hello folks,
I'm newbie on NRF, I have NRF51422 with Keil IDE and I want to create a mesh network on that kit which will continuously broadcast the data of sensors to the...
I am beginner to nrf51 i would like to increase my expertise on nrf51. Are there any recommended books/ tutorials/ weblinks whcih could help me to gain a better understanding...
Hi there,
We have designed our circuit board with the nRF52832 chip. One of the GPIOs is used to monitor a 12V power supply. We use a voltage divider on the 12V so the...
Hi.
I want to ask Nordic employees about the Queued Writes module. Tell me please, is this module required for all applications? If it is not required, then why in all examples...
