Hi everybody,
I need to preserve 3 pages of data in flash memory during DFU. I know there is the macro DFU_APP_DATA_RESERVED defined in dfu_types.h but, I was wondering...
We need to sample two digital inputs GPIOs at rate of 100khz-1mhz. How can we do that?
The QDEC is only good for up to 128us (~7khz) which is too slow for us.
Is there a...
I'm not able to get clear/un-corrupted data across the ttyACM on the nrf52840-PDK. I must be missing something, seems like this would have been solved a million times, but...

What is the typical expected receiver sensitivity when performing BER test (1Msps, 16 byte packets) of the radio module ? The spec refers to 2 values: -93 and -96 dBm (p.231...
Hello,
We are considering merging the Eddystone and iBeacon features together, packet types toggling at each interval tick, then we assumed that we should take the Eddystone...
My device is sending a beacon under DEBUG, but not under RUN.
The issue started when I converted the scan_and_forward example to use a 16-bit device address.
It steps...
Dear Sir or Madam,
I'm using a dev kit with the nRF52832 to realize a project in school. So my work contains two wearables and both include the nRF52832. Now I want to communicate...
