# Target test running OTA update
## Overview
The aim of this test is to exercise the most commonly failing scenario, running OTA over PPPoS with https.
This project opens a data session, runs basic mqtt operations and initiates OTA update.
It supports the following test configurations:
* Using a real modem device (default config)
* Using VFS device (only to exercise VFS DTE)
* Using network-only DCE (connecting directly to PPP server) -- needs some configuration
### Configuring the PPP server
You need to run these applications on your host machine:
* PPP server
```bash
sudo pppd /dev/ttyUSB1 115200 192.168.11.1:192.168.11.2 ms-dns 8.8.8.8 modem local noauth debug nocrtscts nodetach +ipv6
```
* MQTT broker: Running mosquitto in the default config is enough, configuring the broker's URL to the local PPP address: `config.broker.address.uri = "mqtt://192.168.11.1";`
* HTTP server: Need to support HTTP/1.1 (to support ranges). You can use the script `http_server.py` and configure the OTA endpoint as `"https://192.168.11.1:1234/esp32.bin"`
