I am having an issue with huge consistent lagg between laptop and blueboat, connected with Type C cable to basestation.
Placing in different location 1-10 meters appart from each other doesnt make any difference. Placing them in open space outdoor (free of any wifi and radio polution) doesnt make any difference. I have consistently messages that failsafe of heartbeart lost and the whole telemetry losing it. BlueOS keep disconnecting and connecting back with a bunch of errors that it can’t connect
This message appears as yellow mark: “It looks like you are reaching BlueOS via its wi-fi network. This can result in degraded performance.” I mean…yes I am suppose to use the wifi.
Video is dropping a lot of packets. In other words it’s not usable.
The system keep connecting and disconecting all the time.
The message about reaching BlueOS typically only shows if you’re reaching BlueOS at it’s IP on a WiFi network the Pi is connected to, not via the BaseStation. Are you sure you’re loading BlueOS at 192.168.2.2?
What camera are you using, and if the exploreHD, have you adjusted the bitrate to use less bandwidth?
Double checking the ethernet connector in the BlueBoat at the Mikrotike radio is secure is a good first troubleshooting step…
Can you share a screenshot of the signal strength of connected devices available at 192.168.2.3?
I am using blueos at 192.168.2.5 (changed it from the 192.168.2.2 so the ROV won’t conflict it). But regardless of ROV even powered on it still showing this lag issue.
Camera bitrate tested on 0.1 to 10mbits it’s just changed the quality of the image but not the stability of packets which is still dropping consistently.
Worth to mention using the ROV with tether 100m (x fathom) where I have 4 explore hd cameras 'connected on rpi on 10mbits for each stream never caused such issue (except for minor packet drops occasionally) .
I can share the screenshot from the mirkotek tomorrow
There’s no substitute for copper and a direct connection when it comes to bandwidth and packet loss! A 100m tether can provide 50-70Mbit, with 0 dropped packets- a situation where UDP helps reduce traffic my not requiring confirmation of every packet received like TCP. But for radio connections, lost packets can cause video frames to not build and thus lag or artifacts occur. Generally the Mikrotika can provide 20-30 Mbit, with a reduction as range increases. This is still considerably faster than the typical 2-10 Mbit a cellular modem can provide in similar circumstances.
Well 20-30mbits, it’s not much considering we have luxury of using radio comms on surface. I suppose there are ways to increase the bandwidth by placing the different antennas/placing it higher considering the frensel zone and harmonics, but generally if the hardware is limited why to use it in the first place, replace it with higher capability? If it’s done for sake of reduce cost production or/and make it more affordable available then (I can’t say for every customer), but I believe when they look at the description that saying that it can go up to 250m with dipole antenna(the included one) they might expect full telemetry AND the video feed. Probably good idea to mentioned it about this limitation.
Anyway, I tried to go to factory settings by the manual, factory settings with blueos boat (reflashing sd card for rpi), tried to switch to 5ghz in the setup of mikrotik, didn’t help much all disconnection disruption happening all the time with 5-20 seconds (connected, disconnected, connected, disconnected). Tried to remove the base station and use that router inside the boat as a access point, but when I tried to change it the router’s os showed me an error that I have some license issue to be able to use that AP station bridge mode. I even tried to replace to a new rpi4 and a new navigator board the same issue.
My solution which is working right now is putting a router like standalone router tplink/netgear that has detachable rp-sma/sma connector for antenna, so I can put a new 50ohm cable from that router to existing mast antenna, needed to create a cable that with coax adapter for rp-sma, needed to remove the plastic house of the router to fit into the hull and drill holes in the plastic guard of the starboard electronics bay so ethernet cable goes directly from boat’s rpi to router that now in the AP mode, now I have 2.4, 5ghz for short range (can be extended with patch or directional antenna) but importantly stable connection and high bandwidth 200-1200mbits depends on distance.
The Mikrotik Radio in the BaseStation is a different model than the BlueBoat, that’s why you weren’t able to setup the BlueBoat as an AP. In our testing, rang was much better with the BaseStation as an AP instead of the opposite case. Additionally, the settings were optimized for maximum range - and a live-video stream was not in the mix! While possible to do, that amount of data can require adjustments.
If you ever powered either radio with the antenna not present, it may have been damaged, which can lead to connection issues!
