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...
Hi to everybody,
I am working with a custom board based on the nrf52832, while trying to integrate to my existing application the DFU functionality I am having problems...
I am trying to measure the ADC on all 8 ADC pins of the nRF52 on the PCA10040. I'm noticing quite large amount on noise on floating lines (up to 0.6V). However my biggest...
We have a device with a main MCU connected to a NRF52832 for BLE communication. Our device have Battery, Heartrate and a custom service. The first implementation used a Sparkfun...
I am trying to decide what Nordic solutions would best support the application throughput requirements seen below. Distance requirements are low (1 meter each link).

Hi there,
I have nRF52840-Preview-DK eval board. I have downloaded the “SDK 13.1.0”. I was trying out the power management example under the folder “..\nRF5-SDK_copy\nRF5...
The 51822 PS mentions a "Nordic Trace Buffer" but doesn't seem to elaborate. I assume this is similar to the Cortex Micro Trace Buffer? Is there any more documentation available...
Hi I'm looking forward to hear if I could program an nRf51822 QFAA without using the development kit/board. The chip I have currently is a N51822- S4AT, from Wireless Tag...
I recently purchased a Rigado BMD-350 eval board (nrf52832) and am trying to use it for creating a simple ble remote project. I am kind of lost.
As I look through the heart...
I'm testing with pca10028, ASCS(SDK11.0.0) example and iphone.
But pca10028 does not piar after deleting piaring information in iphone.

Hi Nordic developers can someone provide me an example for a simple serial application for nrf51822 BLE?
I have tried uploading the application using Arduino ide and blackmagic...
Hi,
I am trying to develop a custom board using NFR52832 which involves writing data to a NAND flash.
To download data from NAND to the pc, a ftdi cable (C232hm) is used...
Hello,
I'm implementing a custom service and followed the tutorial here . I added a second characteristic by adding its own char_b_init function, creating a CHAR_B_UUID...
Once I call sd_ble_gatts_hvx() while ble connection handle is invalid(BLE_CONN_HANDLE_INVALID), I can never update notification value using sd_ble_gatts_hvx() though function...
