Since I want to achieve the maximum speed of transmission I used the FIFO buffer...
I am having issues waking up nRF52 with s132 using the RTC interrupt. The same code is used on nRF51 with s130 and does not show this behavior.
The RTC is configured and...
Hi,
is it possible to have the same configuration as in the example ble_central_and_peripheral but with ant+ as peripheral (on nRF52)?
Thank you for your attention
I am doing externally triggered SPIM transfer on the Nrf52 using PPI.
I found that the NRF_SPIM_TASK_SUSPEND is a very power hungry operation as SPI suspend waits for the...
Hello
I have a nRF52-DK and I am trying to programme an external designed by myself but this one contains the nRF51422 chip. I am using nRFGO Studio to upload the .HEX...
