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,
I would like first nRF51822(device 1) to use Gazelle library to talk with another nRF51822(device 2) and the same first nRF51822 to use Bluetooth to connect to another...
Hello,
i'm currently looking into ble-bcast-mesh with the goal to transfer a large amount of data (up to 1kB) from one node to another. ble-bast-mesh is working (as far...
Using GCC 4.8.4, it seems to me, that the nrf52_common.ld shiped with the sdk version 12.2 contains a bug:
If an image is defined where the .text data fits into the flash...
I am attempting to connect and send data between an nRF51422 (DK) running the UART Peripheral Example Code and an nRF52832 (DK) running the UART Central example. I am able...

There is a corner case in pstorage_raw.c that can cause a deadlock between pstorage module and the pstorage system event handler. This in turn will cause all the future pstorage...
Hi,
I just implemented LESC Numeric Match on the NUS service for my peripheral device (based on ble_app_multirole_lesc example). I am able to connect to my device using...
I am using the esb_tx example on an nRF51 DK board modified to send BLE advertising packets at 1 KHz.
I am receiving the packets on a BlueTooth sniffer. The contents of...
Hi,
i'm designing a board based on NRF51822-QFAC chip and i'm using this antenna chip 2450AT43A100E and this balun 2450BM14E0003T .
I put the balun as close as possible...
I have __asm("BKPT #0\n") in my code. When running without a debugger, it seems to generate a hard fault exception (which I can tell because I have a hard fault handler that...
This week I worked myself to a series of what seemed to be problems boiling down to one issue:
The Notification Write Response is lost when bonding has to happen first. ...
I'm trying to save power on my HID keyboard application by disconnecting the Bluetooth link after some time of inactivity. As soon as there are keystrokes to send, the device...
The question has been answered before, but the answer references a document called nAN-29 at this link: www.nordicsemi.com/.../73843444 . Which doesn't seem to be working...
Hello,
We use the PCA00031 dongle running the MEFW 0.9.0 in our production environment to validate a sensors accuracy. The PCA is controlled by a C# test program using...
Could someone explain the pin numbering scheme in regard to the interrupt setup handler?
To be specific, what pin number should be passed to nrf_drv_gpiote_in_init for...
