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.

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...
First,the meizu phone can dfu successfully in the dual bank mode,
So do the 360 phone.
But in single bank DFU,this two kinds of phone failed,
So I make the programm enter...
I'm designing custom board with nrf51822 SOC & using buck-boost converter for powering nrf chip, If I don't add inductors in DCC line how it will effect my custom board. ...
Hello,
In previous version of SDK, I used to use "sd_nvic_systemreset()" function to reset nRF52, but this function disappeared in SDK12.2.0 .
The question is what the...
Hello,
I am receiving the above error on Android BLE app while connecting to my pca10040 based board, and I developed this app with nRF Toolbox as a reference.
I am...
Hi all,
I have understood that sys_evt_dispatch is used for all events that aren't BLE but concern the softdevice.
I start to develop my code on gls_example, here in...
I have an application where I need to synchronize several devices to within 1us using a radio. In order to do this, we need to make a protocol that allows precise synchronization...
We have these Dev Kit Nrf52 and also Nrf51 Bluetooth Smart Beacon Kit. For our application and for the simplest user experience we would like to benefit from update via OTA...
My product only offer a debug interface（SWDIO/REST，SWDCLK，+3.3v，GND），but I learn that the nRF51 DK debug out interface has several pins，such as EXT VTG，EXT GND DETECT，EXT...
hi all:
I am a new user.Now i have a project in which I need to implement a function a host and four devices .I just want to know if i use the example of " gzp_dynamic_pairing...
Is a delay needed between Characteristic updates
I modified the ble_sdk_app_proximity example.
I added x3 services, based on the BLE Characteristics, a beginner's tutorial...
I have 32-bit float numbers, sent to the BLE from SPI.
I can manipulate this into x4 bytes, or actually use sprintf and get a real 6-byte representation of the number.
...
I have taken ble_app_ancs_c_s130_pca10028 example and modified the application to run on our custom board.
The custom board uses NRF51822 (NRF51 IC revision 3).
The following...
Hi,
We are using nRF51822_QFAB (128K/16K), S110 V8.0.0 and SDK V10.0.0 for my development. We are in the need of guest (unbonded), pairing and bonded mode.
