What is mLRS? An overview of a new radio systems designed for MAVLINK (and more!)

[@jaysonrees738]

I finally managed to figure out what MSP stood for. It's MultiWii Serial Protocol. It's hilarious to me that the Wii remote played such a large role in making multirotors accessible to the hobbyist.

[@afkafkafk]

Where can I find more on this history, it seems really interesting

[@jaysonrees738]

@@afkafkafk I don't actually know an awful lot on that. Your guess is as good as mine for finding info.

[@alexbringhurst8881]

Love your videos! I can’t wait until you do one showing us how to use mLRS with a ground control station because you’re the best at explaining this stuff in a way that a dummy like myself can grasp.

[@loukasdrones3038]

Certainly something to keep an eye on as it progresses.Great video thanks

[@tubab72]

Just can not get my head from going "Multiple Launch Rocket System" ......occupational deformity is a thing ;-)

[@Painless360]

Yep, that was one of the challenges I had searching for information about it! 😉Happy flying!

[@farruxbek]

I use both ELRS and mLRS on my prototype quad. Matek mLRS has an alternative firmware that makes it process only mavlink data without RC control info (just like SIK telemetry radios). So mLRS transmitter module is connected directly to PC (ground station) via USB, whereas my radio controller uses ELRS

[@adbas6201]

Where did you get this alternative firmware ?

[@RoiS82]

Are they both running on the same frequency?

[@r7_guy941]

Thanks for this video, hope you can make a video soon where you can demonstrate this in action.

[@mikeb5556]

A very interesting video and I am definitely going to investigate with aim to trying out. It seems better performance with less complexity regarding control and telemetry links with radio and a ground station. Thanks for insight. A video on its use with Mission Planner and MAVLink messages for companion computers would be great.

[@rodrigonh]

Nice to see mLRS getting traction. It looks interesting.

[@samhyams]

I've been using the Matek mLRS hardware for a couple of weeks as a telemetry radio replacement, and as far as I'm concerned it basically makes SiK radios/RFD900s totally redundant - you get better performance at a much lower price with mLRS. I've just added an external battery to my ground modem (the Matek Tx module) so I can connect my GCS with mission planner via bluetooth to the Tx module which connects to the aircraft - no more USB at all!

[@khimbittle7705]

Interesting video, pls do additional videos on this subject

[@miketere1]

Great overview and convinced me to order to play with!

[@jeneilpringle215]

Was hoping you would do a video on this!! Great video with great information once again!

[@MCsCreations]

Really interesting indeed! Thanks a bunch, Lee! 😃 Stay safe there with your family! 🖖😊

[@adbas6201]

Thanks lee, with this very good video and following mlrs since a couple of years, i just bought a set of mlrs from matek. In fact I have a quite complete (I think) grou,d station : video analog/openhd on 15" screen and telemetry on a 10" tablet, If I loose video I can fly with telemetry and vice/versa. Thanks again

[@6.5creedmoorrips6creedmoor2]

Need to order asap. Thanks painless

[@gaberivolta]

Great video thanks for sharing. I would be interested in seeing more about this product and its uses with a GCS. Particularly having it configured with QGC (px4 and ardupilot) showing its features. Also, how is this different (or similar) to the crossfire MAVlink feature or rc and telem ?

[@jlarson42]

Very interesting and informative video. Thanks for sharing. 👍😎

[@crypton7951]

Such a great vid thank you for making this.

[@CosmicSlopVibrations]

New era of fpv, MLRS x OPENIPC 🚀

[@NorgeSquad]

But does Matek send their hardware to the devs for testing? Wich they stopped doing with ELRS so ELRS devs says to avoid Matek hardware

[@CosmicSlopVibrations]

Second this. Matek is dodgy. Their airspeed sensors are completely useless and inaccurate, flight controllers are fragile, customer support questionable, etc.

[@sesesp]

You can also check out Ultimate lrs for mavlink telemetry and RC-Control!

[@r7_guy941]

Can you also explain theYaapu telemetry script, and when to use this script. It seems to me that you do not need it with the above hardware ?

[@Painless360]

The telemetry script is just a way to display the MAVLINK telemetry in a useful way on the radio screen... See my videos on it. Happy flying

[@semadragun]

Much potential!

[@geofrancis2001]

it's the lightest mavlink LRS system out there, i used it for my 250g 1 hour ardupilot quad.

[@RaviSingh-wk7qk]

Wow. Do you have a blog for this quad setup? I would also like to build one.

[@geofrancis2001]

@@RaviSingh-wk7qk just search for 250g 1 hour ardupilot, i cant link it or youtube deletes it.

[@dpkgray]

There are ELRS receivers with 500mW telemetry available. Foxeer has them, perhaps other brands do as well. I don't really see a significant advantage, time will tell.

[@pfeerick]

Plus you can use some transmitters in reverse as a receiver, so you can have a 1W telemetry ELRS "receiver" if you so desire.

[@spacekip38]

Looks very interesting! How would this stack up against the recently released Gemini-X?

[@geofrancis2001]

it makes no difference to how it does mavlink.

[@SparkyFlight]

Thanks Lee for a great introduction to mLRS. It raises a question for me. Won't the airside transmitter be legally limited to 25mW in the UK and Europe? The same way that FPV transmitters are?

[@Painless360]

A lot of the latest stuff (like ExpressLRS 900mhz) isn't yet compliment with UK or EU laws... Happy flying

[@geofrancis2001]

you can turn the power level down, I rarely put it above 10mw unless im planning on long range or behind things.

[@uavr1286]

don't forget some professional users can also get licences for higher powers.

[@Zollt76]

Thats fantastic . now i have to get this to play with to hahah to much stuff not enuff time ;)

[@timothius9000]

Good Morning! this looks really interesting from a RubyFPV point of view, can the groundstation end be operated directly over USB or would i need the usual USB-->UART adaptor? (rubyFPV connects to all it's (up to 4) radio devices using USB)

[@Painless360]

The stuff I have seen so far has used a wireless link.. Happy flying

[@samhyams]

You can do it directly via USB, or use the bluetooth, just need a firmware swap (I've done both)

[@stratos2]

How much more performance does this bring compared to ELRS mavlink-rc?

[@Painless360]

On what respect?

[@stratos2]

@@Painless360 you show off elrs as mostly an RC contron protocol, while mavlink rc actually pushes quite a bit of telemetry through the elrs link. I would be curious to see how data rates compare between the two systems. The video kinda made it seem like you were comparing normal elrs telemetry with mlrs.

[@Painless360]

Serial data throughput numbers are in the docs already. The different packet sizes and associated terror checking mean that they are similar in that respect... Happy flying

[@andyMSH700]

now thats impressive the amount of info that is in that brain of yours....you would give Albert Einstein a run for his money on this one.....great work...and wow

[@oneistar6661]

isnt this the same as airport? I had mediocre results with airport via elrs on 900mh

[@Painless360]

See the comments on that near the start of the video. MLRS is very different

[@fazrulrusdi3709]

Mavlink supported radio comm starts way earlier than elrs..but elrs reach the user faster than the rest...good to see people start looking into this radio link as i always want to have bi directional telemetry and thats holding me from jump to elrs system up to now..😅

[@terminsane]

Is this because matek and elrs team are at odds with each other? I wonder

[@Painless360]

I asked but Matek refused to comment... Happy flying

[@FreeEditsForYou]

they'd be smart to team up or make things cohesive. Only makes the hobby bigger and more inviting to people who are as not tech friendly

[@revodrvr]

At this rate. Before long we will tranfer our soyl to a mini quad. Go rip it. Then come back and go back to our body. Things are moving so fast these days.

[@burntnougat5341]

Elrs 3.5 kinda made mLRS irrelevent

[@geofrancis2001]

The main difference is Elrs is a fast RC system that can do slow telemetry, mLRS is a fast telemetry system that also does RC.

[@stratos7755]

Didn't ELRS just introduce something like this?

[@Painless360]

They added some great new support for MAVLINK in their latest release but that doesn't change the differences with packet sizes and the available room for the serial telemetry via mLRS... Happy flying

[@bjowitt]

If you wanted minimal latency for FPV multicopter control and a great Mavlink feed and had a spare UART, is there any problem with using a separate MLRS system for the telemetry as a lighter, neater alternative to the current Mavlink Rxs that are sold now?

[@geofrancis2001]

@@bjowitt in what scenario would going from 10ms and 30ms rc latency make a difference?

[@helidude71]

ELRS should leave all this Mavlink stuff to the mLRS team. Makes much more sense.

[@farkhodkhikmatov4738]

I use the new mavlink rc and it's actually not too bad. But MLrs definitely steps it up
