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 have a question about using the "Radio" peripheral on the NR51422 Dongle development ki
I am putting together a fairly simple prototype device that needs to transmit...
Hello,
I started development on a NRF52832 board couple of days ago. I want to get sensor's data via SPI (with the NRF52 as a master). However I've got weird linking issue...
when creating a pairing with a peripheral, the application fails to exhange keys to allow for random private addressing so the peripheral cannot reconnect because the address...
Hello,
on your product info page, the operating temperature range for the nrf81522 is indicated as -40..+105C, while on the datasheet the same value is -25..+75.

Hey,
I`m experimenting with the blinky ble example in SDK 12.
Everything works fine with the Android nRF Blinky app.
But I noticed a weird behavior when using nRF Connect...
I have tried extracting Bluetooth address of connected device by using "ble_gap_addr_t" ,
by this i am able to get some address but that address is being changed after re...
Hello,
I've managed to get the change to DFU working from my app, but now I'm stuck with the buttonless DFU BLE operation. I've added extensive logging to the <nRF5_SDK...
Hi, I'm working on porting my application from SDK 11.0 to 12.2.0 and I have a problem initializing the buttonless DFU service. I've flashed the secure bootloader and appropriate...
Hi:
I just got an nRF52832 development board, I have ran the tutorials using Eclipse and I was able to run the blinky example.
I am now trying to get a BLE application...
Hello,
As far as I understand previous versions of DFU BLE bootloader implemented a timeout so if DFU is not being used and an app is present it will run after a few time...
Hi,
I want to OTA firmware upgrade of STM32 (External MCU) using nRF51 through Android App on BLE. STM32 and nRF51 communicate on UART.
Please any one suggests how to...
My project based on nRF52832 and SDK is 12.2. I need to support alert notification(service UUID 0x1811) client profile for mobile device, I just build and download the nordic...
