## This repo is currently a work in progress 
- The README.md will be fully updated once the repo is in a stable state


## TODO
- Need to automate Rust project (xbnet)
    - Configure (looks good)
    - Build
    - Deploy
        - On Ubuntu for testing
        - On Linux for Tegra for TX2
        - On Jetson Orin
- Working on setup_host_device.sh
    - Issues with bridging interfaces
- Need to add setup_end_device.sh
- Need to dockerize service
- Possibly may need to bridge docker xbnet network with local wifi interface as well
- Make a submodule of xbnet, or copy over raw files, depending on future decisions

# SERVICES-XBEE_NET

This project contains a Dockerized setup to create and manage an XBee network using the `xbnet` utility. The network interface is bridged with a host Wi-Fi interface, enabling internet access for connected devices.
##### Note: This project uses the `tap` xbnet protocol, which is a layer 2 protocol. This supports full ethernet pipeline. For a simple IP level protocol support, the `tun` xbnet protocol can be used.

```

## Prerequisites

Ensure Docker and Docker Compose are installed on your machine.

## Getting Started

#### 1. Clone the Repository

```bash
git clone https://git.spirirobotics.com/Spiri/services-xbee_net
cd services-xbee_net
```

#### 2. Run a single xbnet node using the following cmd:

- Router mode:  `sh ./run-single.sh --subnet=7.7.7 --serial-speed=230400 --port=/dev/ttyUSB0 --interface-type=router`
- Gateway mode: `sh ./run-single.sh --subnet=7.7.7 --serial-speed=230400 --port=/dev/ttyUSB0 --interface-type=gateway`  

##### NOTE: This setup assumes that you have an XBee device connected to port: /dev/ttyUSB0


#### 3. OR Manually build and Start the Docker Container

##### NOTE: This will require the config `.env` to be manually modified, based on user needs.

---
- Configure a single xbnet net service using:

    ```bash
    # Configuration for xbnet0
    XBEE_PORT=/dev/ttyUSB0
    XBEE_BAUDRATE=230400
    XBEE_NET_SRC_IP=192.168.1.100   # Ensure this IP matches the network range
    XBEE_NET_IFACE_NAME=xbnet0

    # Default Gateway
    DEFAULT_GATEWAY=192.168.1.1
    ```

- Configure multiple xbnet net services using:

    ```bash
    # Configuration for xbnet0 (REQUIRED: minimum config to run a single xbnet node)
    XBEE0_PORT=/dev/ttyUSB0               # The serial port for the XBee device
    XBEE0_BAUDRATE=230400                 # Baud rate for the XBee device
    XBEE0_NET_SRC_IP=192.168.1.100        # Source IP for the XBee network
    XBEE0_NET_IFACE_NAME=xbnet0           # Interface name for the XBee network

    # Configuration for xbnet1 (OPTIONAL: only required for multi node xbnets)
    XBEE1_PORT=/dev/ttyUSB1
    XBEE1_BAUDRATE=230400
    XBEE1_NET_SRC_IP=192.168.1.101
    XBEE1_NET_IFACE_NAME=xbnet1

    # Default Gateway (REQUIRED: part of minimum concifg to run a single xbnet node)
    DEFAULT_GATEWAY=192.168.1.1
    ```
---

To build the Docker image and start the container, run:

```bash
docker-compose -f docker-compose.yml up --build
```

This will build the Docker image and start the container with the XBee network and the required setup.

#### 4. Health Check and Container Management

The container includes a health check that pings the XBee network interface to ensure it is functioning properly. \
The container is configured to restart automatically if the health check fails.

#### 5. Troubleshooting

Ensure the XBee devices are connected to the correct serial ports.\
Verify the network interfaces using ip a inside the container.\
The container logs can be viewed using:

```bash
docker logs xbee_node
```
