# MAVLink Forwarding (IGC 1.5.4 Beta)

## Herelink MAVLink Forwarding

The Herelink allows for Telemetry sharing without the use of IGC, by simply connecting the Herelink's hotspot to the device to share telemetery. Programs such as UgCS, Mission Planner, and QGC on a laptop or Android Device will automatically detect telemetery, as Herelink telemetry is shared over UDP port 14550, the default UDP port. 

[Follow these instructions to enable telemetry sharing on the Herelink GCS.](https://docs.cubepilot.org/user-guides/herelink/herelink-user-guides/share-video-stream#connect-over-wifi-hot-spot)

## GS-ONE MAVLink Forwarding

Telemetry sharing on the GS-ONE is enabled through IGC, and can be conducted either using the GS-ONE's hotpot, or by connecting the GS-ONE and a second device (laptop or Android device) over the same wifi network.

{% hint style="info" %}
Note: The GS-ONE forwards over UDP Port 14560, not 14550, so proper configuration of Mission Planner, UgCS, QGC etc must be made to make a vehicle connection. See "[Configuring UgCS for GS-ONE Connection](#configuring-ugcs-for-gs-one-connection)" section below for instructions on connecting with UgCS."
{% endhint %}
