## Installing `nrfutil`
The Adafruit Bluefruit nRF52 Feather ships with a serial and OTA BLE bootloader
that can be used to flash firmware images over a simple serial connection,
using the on-board USB serial converter.
If you haven't installed this command-line tool yet, go to the `/libs/nrfutil`
folder (where nrfutil 0.5.2 is installed as a sub-module) and run the following
commands:
> If you get a 'sudo: pip: command not found' error running 'sudo pip install',
you can install pip via 'sudo easy_install pip'
```
$ cd ../../libs/nrfutil
$ sudo pip install -r requirements.txt
$ sudo python setup.py install

## Building CircuitPython binaries
#### REPL over UART (default settings)
To build a CircuitPython binary with default settings for the
`feather52` target enter:
> **NOTE:** `BOARD=feather52` is the default option and isn't stricly required.
```
$ make BOARD=feather52 V=1

#### REPL over BLE UART (AKA `NUS`)
#### REPL over BLE support
To build a CircuitPython binary with REPL over BLE UART, edit
`bluetooth_conf.h` with the following values (under
`#elif (BLUETOOTH_SD == 132)`):
```
#define MICROPY_PY_BLE (1)
#define MICROPY_PY_BLE_NUS (1)
#define BLUETOOTH_WEBBLUETOOTH_REPL (1)
```
Then build the CircuitPython binary, including `SD=s132`
to enable BLE support in the build process:

The Adafruit Bluefruit nRF52 Feather ships with a serial and OTA BLE bootloader

These commands assume that you have already installed `nrfutil`, as described

## Working with CircuitPython
### Running local files with `ampy`
[ampy](https://learn.adafruit.com/micropython-basics-load-files-and-run-code/install-ampy)
is a command-line tool that can be used with the nRF52 Feather to transfer
local python files to the nRF52 for execution, rather than having to enter
the REPL manually, enter paste mode, and paste the code yourself.
> **IMPORTANT**: You must have `ampy` version **1.0.3** or higher to use `ampy`
with the nRF52. The bootloader on the nRF52 requires a delay between the
HW reset, and the moment when the command sequance is sent to enter raw
mode. This required `-d/--delay` flag was added in release 1.0.3.
Save the following file as `test.py`:
```
import board
import digitalio
import time
led = digitalio.DigitalInOut(board.LED2)
led.direction = digitalio.Direction.OUTPUT
while True:
led.value = True
time.sleep(0.5)
led.value = False
time.sleep(0.5)
```
Then run the saved file via ampy, updating the serial port as required:
```
$ ampy -p /dev/tty.SLAB_USBtoUART -d 1.5 run test.py
```
This should give you blinky at 1 Hz on LED2 (the blue LED on the nRF52 Feather).
### Uploading files and libraries with `ampy`
To upload Python files or pre-compiled CircuitPython libraries to the `lib` folder,
run the following commands:
> In this example **i2c_device.py** is used, which is part of
[Adafruit_CircuitPython_BusDevice](https://github.com/adafruit/Adafruit_CircuitPython_BusDevice)
```
$ ampy -p /dev/tty.SLAB_USBtoUART -d 1.5 put i2c_device.py lib/i2c_device.py
```
To verify that the file was uploaded correctly, you can check the contents of
the `lib` folder with:
```
$ ampy -p /dev/tty.SLAB_USBtoUART -d 1.5 ls /lib
i2c_device.py
```
### Suggested libraries
The following libraries should be installed as a minimum on most new boards:
- [Adafruit_CircuitPython_BusDevice](https://github.com/adafruit/Adafruit_CircuitPython_BusDevice)
- [Adafruit_CircuitPython_Register](https://github.com/adafruit/Adafruit_CircuitPython_Register/tree/master)

# Adafruit nRF52 Feather Single-Bank Bootloader
These files contain an implementation of a single-bank bootloader,
which doubles the amount of flash memory available to applications
at the expense of safe over the air updates.
Two versions are present, based on release **2.0.1** and **5.0.0**
of the Nordic S132 SoftDevice. The SoftDevice is included as poart
of the bootloader binary.
