BlueOS does not connect to QGC

Following the instructions from the BlueBoat Software Setup doc, we can see the boat and the PC connecting to the Base Station. (.2.2 and .2.1) However, the “Last IP” sometimes changes between 2.4 and 2.2 and just being blank.

We updated BlueOS and Ardupilot firmware and paired the base station with the boat. When connected to the base station with the boat on it will not appear on QGC, but we can access BlueOS and all other related IPs through the browser.

Despite this we are unable to get QGC to link to the boat for control and plotting.

Any insights? What am I missing?

Hi @kenbyrrrd -

If I understand correctly, you’re able to load BlueOS (at 192.168.2.2?) in your browser but are not getting a connection in QGC?

If so, either your firewall is blocking the port QGC is trying to receive telemetry on …
or
You don’t have a MavLink UDP Client endpoint targeting your control computer’s IP address (which should be 192.168.2.1, and already exist in the list in BlueOS - add it if it doesn’t to fix!)

What version of BlueOS do you have installed?

Hi @kenbyrrrd

I would also double and triple check the subnet mask in your computer’s network settings. An incorrect subnet mask (anything that is not 255.255.255.0) will cause issue with QGC connection, even though you’re able to access BlueOS through the browser.

Hi @tony-white ,

Thanks for the help. we installed the most recent version today - can’t remember exact name. we followed the directions in the software setup guide for firewalls settings.

I believe it is an endpoint issue - but unsure how to approach this. viewed some settings in pirate mode in BlueOS as well as in QGC.

For some background, today we followed the software setup guide all the way through, including manually pairing the base station and boat. Everything went to the letter until opening Q

Hi @DanielG_BR thanks for this. When we change the WiFi settings, the subnet mask autofills to that exactly

Hi @kenbyrrrd -

Are you using Mac or Windows? I recently helped a user that had a similar situation, and only when the firewall was disabled did a connection to QGC immediately come through…

If that’s the fix, you could add QGC to your firewall exception list and turn the firewall back on?

@tony-white we will try this. I will let you know how it goes! Thanks
