thUndeadMod v3.4 - openLRS S**T just got real :)

[Cat695]

Its that good I did it......without help

Cheers

[thundead]

Competition tomorrow:D




Now you know why I haven't been adding anything to the fw lately lol :D

Diving UAV??

[Devonian]

A submersible!

Best of luck with R/C signal levels, unles it has an umbilical?

Nigel.

[thundead]

yup, its an ROV. 3 cameras, grabber, pressure sensor, 4 arduinos running the whole show lol (2 megas for controls and 2 minis for camera OSDs because I can :D)

nothing off the shelf :D electronics and some programming done by yours truly :D

Uses a 20m tether :)

Diving UAV??

Looks cool :)
A mate of mine is building one for his university project.

John ask me to post this for you guys to have a look at







I was going to do a video but would be here all night uploading so hopefully my explanation will be enough.....trying to keep it brief though.

Today I went to do a LOS flight on the new FW (V3.5). Took off and flew 200m and lost control...(plane safe) was powering the openLRS Rx from the ESC (2 amp 4 servos only) antennas are extra from Simon (mono pole ones on both Tx and Rx)

So fitted a BEC (8.5amp 5v) did a range test by wondering up the road and seemed to get 3 times as much than the flight!

John (AKA Papa) asked me to hook up a multimeter to pin 1 GRN and Signal pins and check the output........with Tx off should be nothing or very low, correct?

With Tx on it should jump and stay up at 3+ volts....but as you can see from the pics it doesn't, it constantly jumps from 0 to 3+ volts

Tried 2 different BECS and still the same....John thought it best to pass this on to you guys as he thinks theres a problem.

There is a problem there. With my tests last night, the RSSI did not bounce to those extremes. 0.3 v typically. I would reflash your board (rx) and try it again

[papa_lazerous]

I still have to flash to the new version as I slept most of today away instead of flying (joys of night work) I may do a quick instructional video just so everyone has something to follow and we can eliminate silly mistakes from the mix straight away

[Coyote]

I'm going to repeat my ground test tomorrow at the same place as previous one, and the weather is the same. So it will be the 459mhz this time and 3.5 software. If I get similar results we will know. But I've flown out 1.4km on Sunday on 3.3 software so I'm not expecting and real differences in results other that RSSI values

I did not do any range testing but did load up 3.5. It does seem to be much better.

I noticed before that from time to time my RSSI was dipping (seem as a return to home on my RVOSD). I was not sure what caused this but if you are saying that a timer was on the pin for RSSI then that could be the cause.

WIth the RSSI on pin 1 I did not experience any of these fluctuations and the RSSI was very solid. I am using a CC BEC (10A).

A 2A BEC with 4 servos on it does sound a bit close to the edge.

yep I thought that but its even doing it on a 8.5amp bec Trevor
