What's new

  • Network settings per flight controller. Open the External FC menu and click Network on any integration card to set the SITL host and every port it uses.

  • Test connection button — check the address is right before you activate.

  • Hostnames work, not just IP addresses.

  • Settings are remembered between sessions, per flight controller.

Betaflight

Betaflight sends its motor output to a single address it is given at launch, so a remote setup needs one extra step: start the SITL pointing back at the machine running SITL Forge.

betaflight_SITL.elf --ip 192.168.1.50

(On Betaflight 4.5.x, pass the address as the first argument instead.)

iNAV

Nothing to configure on the iNAV side — set the host in the Network window and you're done.

Using WSL?

The Setup help panel on each integration card now has a full walkthrough, including the two things that trip everyone up: the Windows Firewall rule for the motor data, and the mirrored networking option that removes the need for any of it on Windows 11.
