On a BLE_GAP_EVT_CONNECTED, I'll send some data to an attached microcontroller via UART. The code will expect a response of that data, all while being inside that BLE_GAP_EVT_CONNECTED...
My application involves the Nrf52 using softdevice and a slave only SPI ADC running at approximately 26khz. The ADC has a pin interrupt to indicate data ready. There seems...
Building nrf_delay.c (or anything else including nrf_delay.h ) with NRF52 defined produces:

Hello Nordic community:
I've read about Serialization in the nRF51 SDK doc and would like to prototype an example with it.
I saw a notice of it being removed post 7...
Hi,
Is it possible to get a more detailed description of the GPIO block than what is available in the reference manual? Specifically i'm interested in how the disconnect...
Hello Everyone,
I want to run a couple of test on the nRF51422 radio. However, how do I go about checking the firmware on these devices without the use of a motherboard...
