I have used the nRF5_SDK_11.0.0_89a8197\examples\ble_peripheral\ble_app_proximity\pca10028\s130\armgcc for my project before I had the final PCB. I have tested my code on...
Hello,
I was wondering why I am not getting a theoretical sampling rate as I set them to with a timer.
I am using PPI to trigger a SAADC sampling with the timer to set...
Hello!
Nordic UART Service (NUS) is a pretty handy way of implementing a serial data transfer service over BLE. The nRF Toolbox on Android makes it very easy to test it...
Hi,
While this is not related to Nordic Semiconductor products, I think we should incorporate Captcha system during user registration. We had some spam in the morning and...
I need to be able to actively set the value being incremented in the Timer2 register on the nrf52 (what I believe would be it's main register). It seems that this might be...
Hi,
is there any example how to reset the hole device? Are there any example codes for using something like system_off or system_on ?
Best regards Nils

Hi guys,
I am trying to create a Dual bank DFU bootloader (BL) program for nRF51822 which will be able to update the SoftDevice and bootloader no matter if the "Enable...
Hi,
Sorry if the answer is obvious but I'm not getting it :-)
I looked at ble_app_uart, more specifically the uart_event_handle function and its interactions with app_uart_fifo...
I want to access an SPI-only sensor device from a Blend Micro.
There is a need to avoid collisions between the two uses of the SPI port for the sensor and the nRF chip...
I just made it to upload the example to the device. I'm new into firmware development btw.
I changed the timeout so the beacon will stop advertising after 120 seconds but...
Hello, I have implemented the code below for my project
