System Integration Test Specification

Lists tests to be conducted before every new release

Prerequisites

• All Pis need to be operated using a power supply rated at least 2.1A 5V

• All connected adapters shall be connected via an active USB hub or have a separate USB power supply. Do not power via RPi USB ports!

• All tests are conducted in a noisy environment with a distance of 1-20 meters between GND & AIR

Startup

• Sucessful startup of all modules with a Pi3B in GND configuration

  • Using one AR9271 driver based adapter

  • Using two AR9271 driver based adapters

  • Using one RTL8814AU driver based adapter

  • Using one RT2800 USB driver based adapter

• Sucessful startup of all modules with a Pi3B in AIR configuration

  • Using one AR9271 driver based adapter

  • Using one RTL8814AU driver based adapter

  • Using one RT2800 USB driver based adapter

• Sucessful startup of all modules with a Pi0W in AIR configuration

  • Using one AR9271 driver based adapter

  • Using one RTL8814AU driver based adapter

  • Using one RT2800 USB driver based adapter

Video Transmission

• 15min stable video transmission using system default configuration between:

  • Pi3B (AIR) - Pi3B (GND) using a single AR9271 based adapter each

  • Pi0W (AIR) - Pi3B (GND) using a single AR9271 based adapter each

  Connection via HDMI out. Connection via WiFi hotspot and DroneBridge for Android.

• Data stream connection loss test: Auto reconnection after a lost signal event simulated by putting the AIR unit into a microwave oven using AR9271 cards.

Telemetry Transmission

• 5min stable MAVLink telemetry transmission using system default configuration:

  • Pi3B (AIR) - Pi3B (GND) using a single AR9271 based adapter each

    Waypoint mission upload using QGroundControl

    Start/Stop mission using QGroundControl

Communication Module

• Successful settings change on GND and AIR using DroneBridge for Android and a WiFi connection to the GND station

• Successful settings request from GND and AIR unit using DroneBridge for Android and a WiFi connection to the GND station

RC Link

• 15min stable RC link using a Taranis based RC with OpenTX 2.2 firmware

  • Connection loss/recovery test by simulating a connection loss inside a microwave oven

  • Min of 30 packets/s at AIR unit at all times

  • Video and RC simultanious

  • RC USB connection loss test: Unplugging RC from GND station -> failsafe event

  • RC USB auto reconnection on re-plugging RC to GND station -> full recovery

USBBridge Transmission

• Autostartup of DroneBridge for Android on connection

• 15min stable video & MAVLink telemetry transmission to app

• Communication module settings change on AIR and GND

• Auto-recovery of data streams on USB cable reconnection
