Redbear Labs Nano v2
####################

Overview
********
The Nano v2 is a development board equipped with Nordic's next generation nRF52832 Bluetooth Low Energy SOC.
This board was designed as a 'drop-in' replacement of BLE Nano with exactly the same form factor.
This board will be available for Kickstart backers on February 2017.
It is also available on Redbear store.

The DAPLink USB board acts as a dongle. DAPLink debug probes appear on the host computer as a USB disk.
It also regulates 5V from USB to 3.3V via the onboard LDO to power Nano v2.


Programming and Debugging
*************************

Flashing
========

Build the Zephyr kernel and BLE sample application:

.. code-block:: console

   $ cd $ZEPHYR_BASE
   $ . zephyr-env.sh
   $ make -C samples/bluetooth/beacon BOARD=nrf52_blenano2

- Mount your BLE Nano v2 onto the DAPLink USB dongle correctly.
- Connect DAPLink USB dongle to your host computer.
- The PC will prompt a new mass storage disk.
- Copy the generated file zephyr.bin on folder samples/bluetooth/beacon/outdir/nrf52_blenano2 to the DAPLink drive.
- Open nRF Connect application to check advertising packets.
