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...
I'm using SAADC on a NRF52832 DK to read a analog channel between 0-3.3V. I wanted to supply current with the board VDD but it's value is 2.8V and they're not event stable...
Hi
I'm trying to get higher throughput when connected as a central by increasing my Tx&Rx bandwidth to high (from the default medium).
uint32_t nrfErr; ble_opt_t opt...
Hello,
my custom board does not have external 32kHz crystal. I have managed to use NRF_CLOCK_LF_SRC_RC in SOFTDEVICE_HANDLER_INIT instead.
My questions are:

I have a Custom Board made by using nrf51822 soc but pc is unable to detect the board by using Jlink debugger.
Stlink was able to detect only when frequency selected as 20khz...
Hello dear Nordic Team,
I got a question regarding the device filtering options. I am interested in putting 10 chips next to each other. But every chip shall have only...
As I came to understand, all the services & characteristics are registered in a "GATT table" of some sort, so my question:
What are the functions used to create and...
I want to update the nordic device from another MCU with HCI DFU. I cannot figure out how to write the packet header.
In the Nordic documentation, it is writen to read the...
I want to add micro-ecc library for compiling bootloader secure code.
I tried as mentioned on infocenter.nordicsemi.com/index.jsp .
I am getting error as attached. I am...
Hi,
we use the GPIOTE to get informed if the value of a GPIO pin gets from hi to low.
If this happens, the GPIOTE event handler will be called.
What will happen,...
Hi, I'm using a nRF52 dk board as a switch to control a circuit. The problem is I not sure which gpio can be used to act as a switch to control the circuit. Thanks.
I need to append another binary-file (image.bin) to the generated bin-file from my own nRF makefile Project in Eclipse with Cross ARM GCC. My research showed me several possibilities...
Hello,
I have a standalone application which incorporates 3 public BLE services and 2 services with custom UUIDs.
Today I tried to extend the buttonless DFU example with...
Hello,
I have installed Ozone (V2.22g) on Kubuntu (16.10 64bit) and attached a nRF51DK via USB. I can successfully run a test program using nrfjprog with the following...
