Can nrf8001 be used for both ends of beacon?

[pvogel]

I have seen I can use the nRF8001 to broadcast as a beacon, can a second nRF8001 pick up this beacon? If not, what is the smallest device that will do the job?

The nRF8001 is a peripheral/Broadcaster only. If you need a Central or Observer(scanner) you should look at the nRF51 or nRF52. I would use the nRF51/52 as both beacon and scanner as this means you will only have to familiarize yourself with one API/SDK and toolchain.

Hi! Is there any example programs when nrf52 acts as an observer to beacons?

All the central role examples are scanning for peripherals, so these can be used as a starting point for an observer. There is also a separate scanner implementation in \nRF5_SDK_11.0.0_89a8197\examples\ble_peripheral\experimental_ble_app_multiactivity_beacon\hrs_scanner
