{% embed url="<https://www.youtube.com/watch?v=8RYfZdNIpUM>" %}

{% hint style="warning" %}
This firmware is compatible with Herelink aircraft using Gremsy VIO, Sony LR1, Sentra cameras, and LIDAR payloads only. If you have any custom solutions, Micasense, PhaseOnes, A7R, A6500, SROC controllers, LRT models, etc, **this update is not compatible.** Please [contact Customer Success](https://www.inspiredflight.com/support.php) for more info.

If you'd like to schedule a time with our Customer Success team to assist with these updates, please [click here to book a call.](https://calendar.google.com/calendar/u/0/appointments/schedules/AcZssZ3IFQCX28SA9S9agBwapejZs4_Eu-PN1yDGAZ5rhpgqlIW1P_ikvOWMKeprX1eCDRM5G5q_wdss)
{% endhint %}

{% hint style="info" %}
For safety, remove IF1200 batteries and keep IF1200 arms folded and propeller holders installed during upgrade process. Powering on the aircraft is not required for this update.&#x20;
{% endhint %}

{% hint style="danger" %}
IGC missions created and saved using older aircraft firmware will need to be recreated after updating. Outdated mission will prevent aircraft from taking off.&#x20;
{% endhint %}

1. Open [Mission Planner](https://ardupilot.org/planner/docs/mission-planner-installation.html) on a PC.
2. Connect a USB-C to USB-A cable between the aircraft's USB port and the PC's USB port.
3. Connect to the vehicle using the MavLINK Com Port Connection.&#x20;

* **Note:** the COM number may change but always select the "**MavLink**" option.
* Then, select **Connect** in the upper right corner.
* If "MavLink" option is not available, choose "AUTO" and connect. &#x20;
