This daemon allows to set up the wireless network using a bluetooth LE connection. The daemon will automatically start a bluetooth low energy server
if the system is currently not connected to any network. Once the system is connected, the daemon will shutdown the bluetooth server.
# Build
# Configuration
First you have to install build dependencies:
nymea-networkmanager will search for a config file in the following location:
> Note: the `libnymea-networkmanager-dev` package can be installed from the [nymea repository](https://nymea.io/en/wiki/nymea/master/install/debian) or built
and installed from [source](https://github.com/nymea/libnymea-networkmanager).
/etc/nymea/nymea-networkmanager.conf
If such a config file is found, it reads values from there. There is a example config in
this repository and it will be installed to /etc/nymea-networkmanager.conf with the dpkg package.
> Note: Command line parameters will have higher priority than entries in the configuration file.
> Note: the `libnymea-gpio-dev` package can be installed from the [nymea repository](https://nymea.io/en/wiki/nymea/master/install/debian) or built
and installed from [source](https://github.com/nymea/nymea-gpio).

$ nymea-networkmanager --help
Usage: ./nymea-networkmanager [options]
This daemon allows to configure a wifi network using a bluetooth low energy connection.

Modes:
- offline This mode starts the bluetooth server once the device is offline
and not connected to any LAN network.
- once This mode starts the bluetooth server only if no network configuration exists.
Once a network connection exists the server will never start again.
- button This mode enables the bluetooth server when a GPIO button has been pressed for
the configured timeout periode.
- always This mode enables the bluetooth server as long the application is running.
- start This mode starts the bluetooth server for 3 minutes on start and shuts down after a connection.
Options:
-h, --help Displays this help.
-v, --version Displays version information.
-d, --debug Enable more debug output.
-a, --advertise-name <NAME> The name of the bluetooth server. Default
"BT-WiFi". NOTE: The length is limited to 8
characters.
-f, --force-name Enforce the full name to be used even if it is
longer than 8 characters. IMPORTANT: This will
displace the Service UUID in the discovery data
which implies that client applications cannot
discover the wifi setup service on this device
any more.
-p, --platform-name <NAME> The name of the platform this daemon is running.
Default "nymea".
-g, --gpio <GPIO> The GPIO sysfs number for the button GPIO. This
parameter is only needed for the "button" mode.
-t, --timeout <SECONDS> The timeout of the bluetooth server. Minimum
value is 10. Default "60".
-m, --mode <MODE> Run the daemon in a specific mode (offline,
once, always, button, start). Default is
"offline".
-b, --dbus-type <DBUSTYPE> If given, a DBus interface will be exposed on
the chosen DBus bus type (session, system)
# Bluetooth GATT profile
## Bluetooth GATT profile
-------------------------------------------
In order to connect to nymea-networkmanager using bluetooth low energy, once has to perform a bluetooth discovery, filter for all low energy
devices and connect to the device with the name `nymea`. The remote address type for connecting to `nymea-networkmanager` is `public`.
## Notifications
### Notifications
In order to enable/disable the notification for a characteristic with the `notify` flag, a client has to write the value `0x0100` for
enabling and `0x0000` for disabling to the descriptor `0x2902` of the corresponding characteristic.

The *Wireless Service* allows a client to configure and monitor a wireless network connection. The connection can be controlled with the *Wireless commander* characteristic. Each command sent will generate a respone on the *Comander response* characteristic containing the error code for the command. The *Wireless connection status* characteristic informs the client about the current connection status of the wireless device.
