sending data from nRF5340 to Raspberry PI

[tim3in]

How can I send data from nRF5340 to Raspberry Pi? Do I need  nRF52840 Dongle dongle attached to raspberry pi? What functions should be used to send from nRF5340 and receive on Raspberry Pi?

If you meant through the air with rf then you can also use Bluetooth from nRF5340 to raspberry pi.

See the discussion here devzone.nordicsemi.com/.../how-to-send-string-message-from-nrf52840-to-raspberry-pi

Alternatively, you could use openthread, which has the advantage of being able to send messages to every internet device not only the raspberry pi, then you'd need a dongle such as the nRF52840 Dongle.
