# MeshChat on Android
It's possible to run on Android from source, using [Termux](https://termux.dev/).
You will need to install a few extra dependencies and make a change to `requirements.txt`.
```
pkg upgrade
pkg install git
pkg install nodejs-lts
pkg install python-pip
pkg install rust
pkg install binutils
pkg install build-essential
```
You should now be able to follow the [how to use it](../README.md#how-to-use-it) instructions above.
Before running `pip install -r requirements.txt`, you will need to comment out the `cx_freeze` dependency. It failed to build on my Android tablet, and is not actually required for running from source.
```
nano requirements.txt
```
Ensure the `cx_freeze` line is updated to `#cx_freeze`
> Note: Building wheel for cryptography may take a while on Android.
Once MeshChat is running via Termux, open your favourite Android web browser, and navigate to http://localhost:8000
> Note: The default `AutoInterface` may not work on your Android device. You will need to configure another interface such as `TCPClientInterface`.

# MeshChat on Docker
A docker image is automatically built by GitHub actions, and can be downloaded from the GitHub container registry.
```
docker pull ghcr.io/liamcottle/reticulum-meshchat:latest
```
Additionally, an example [docker-compose.yml](../docker-compose.yml) is available.
The example automatically generates a new reticulum config file in the `meshchat-config` volume. The MeshChat database is also stored in this volume.

# MeshChat on a Raspberry Pi
A simple guide to install [MeshChat](https://github.com/liamcottle/reticulum-meshchat) on a Raspberry Pi.
This would allow you to connect an [RNode](https://github.com/markqvist/RNode_Firmware) (such as a Heltec v3) to the Rasbperry Pi via USB, and then access the MeshChat Web UI from another machine on your network.
My intended use case is to run the Pi + RNode combo from my solar-powered shed, and access the MeshChat Web UI via WiFi.
> Note: This has been tested on a Raspberry Pi 4 Model B
## Install Raspberry Pi OS
If you haven't already done so, the first step is to install Raspberry Pi OS onto an sdcard, and then boot up the Pi. Once booted, follow the below commands.
## Update System
```
sudo apt update
sudo apt upgrade
```
## Install System Dependencies
```
sudo apt install git
sudo apt install python3-pip
```
## Install NodeJS v22
```
curl -fsSL https://deb.nodesource.com/gpgkey/nodesource-repo.gpg.key | sudo gpg --dearmor -o /usr/share/keyrings/nodesource.gpg
NODE_MAJOR=22
echo "deb [signed-by=/usr/share/keyrings/nodesource.gpg] https://deb.nodesource.com/node_$NODE_MAJOR.x nodistro main" | sudo tee /etc/apt/sources.list.d/nodesource.list
sudo apt update
sudo apt install nodejs
```
## Install pnpm
```
corepack enable
corepack prepare pnpm@latest --activate
```
## Install MeshChat
```
git clone https://github.com/liamcottle/reticulum-meshchat
cd reticulum-meshchat
pip install -r requirements.txt --break-system-packages
pnpm install --prod
pnpm run build-frontend
```
## Run MeshChat
```
python meshchat.py --headless --host 0.0.0.0
```
## Configure Service
Adding a `systemd` service will allow MeshChat to run in the background when you disconnect from the Pi's terminal.
```
sudo nano /etc/systemd/system/reticulum-meshchat.service
```
```
[Unit]
Description=reticulum-meshchat
After=network.target
StartLimitIntervalSec=0
[Service]
Type=simple
Restart=always
RestartSec=1
User=liamcottle
Group=liamcottle
WorkingDirectory=/home/liamcottle/reticulum-meshchat
ExecStart=/usr/bin/env python /home/liamcottle/reticulum-meshchat/meshchat.py --headless --host 0.0.0.0
[Install]
WantedBy=multi-user.target
```
> Note: Make sure to update the usernames in the service file if needed.
```
sudo systemctl enable reticulum-meshchat.service
sudo systemctl start reticulum-meshchat.service
sudo systemctl status reticulum-meshchat.service
```
You should now be able to access MeshChat via your Pi's IP address.
> Note: Don't forget to include the default port `8000`
