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

[wgt40w]

No posts for a fortnight ?

Come on guys - tell us how the experiments and testing are going.

[thundead]

lool. you're the first to reply to this topic in ages haha :)

I don't even have an openLRS !  It's just that when I joined this Forum someone told me how I could buy one of these from Firstpersonview.co.uk and that they "worked straight out of the box" !!

I like a challenge and I enjoy watching other people following one.

I have studiously followed the ups & downs - even occasional sideways movements of this Thread, hoping one day to see a full determination of what has caused the range problems and how to eradicate those problems on 459 mhz.

(Preferably before the world runs out of 'pringles')  LOL

[thundead]

system works if used accordingly :) I've started work on another firmware (no ETAs yet as barely have time to breathe lol) that will hopefully simplify and make clear to everybody how to properly flash my fw.

Currently there hasn't been any interest in this system though and I'm currently considering buying a rangelink and stop dev lol.

From my point of view the range issues were caused by burned out RF modules resulting from use of inappropriate FTDI flashers (5v compared to the required 3.3v). neither myself or papalazerous had any range issues during our tests.

hello again all....

unfortunately i was one of the stupid ones that tried to flash olrs with a 5v ftdi thing...
not very wise in the end.. (i did see a flyton vid of him just flashing rx's so tried it doh!)

so i ordered a set of rf modules to try and fix the set...
ordered some 2-3 weeks ago now and no delivery or tracking for the UK provided :/
not to happy about that as flytron are pointig the finger at customs now.
we will see...

randomly i found another set of olrs for sale on the forum here.
1x v2 tx and 2x v2 rx's
not really done any testing as yet with these, i will try asap.
(but have now been informed that this HW maybe f**ked as well?)

i am really really wanting to get this flying in the end as its been months and hundreds so far!

thanks again every one who is inputting to the whole olrs thing! it is much appreciated...

i will report back soon with some testing...

I lurk and read many forums and I personally think that folks normally only post when there's either a problem or they are asked directly for feedback on something.

For me the lack of people posting on here is actually a testament to how well thundead's excellent firmware actually works with the olrs hardware.

Just stay away from other overpowered LRS systems and you'll be peachy :)

i did just have a thought.... haha easy now.....

i could flash a tx/rx and use the 2nd rx as the spectum analyser thing to see?

i must admit i down loaded the FW but havnt tried using it yet...
is it easy? will it show if its working correctly or not?

Just tried exactly what you posted. I use my second (not yet installed) Rx and installed the OLRS Spectrum Analayzer FW on it. Started the GUI and selected the range 457Mhz - 462Mhz and started scanning. I turned my Tx on and off and could see the data spikes in the 459Mhz area.

Worked brilliantly.

I guess this would confirm a number of things.
1. Your tx module is working
2. It's working on the correct frequency
3. Your rx RF module hasn't been fried.

[phibin]

what FW did you use... my spectrum thing will only go up to com port 15...?
my ftdi is on com port 49.....?

any ideas...

thats great though just what i was trying to achieve :)

simon.

p.s.

looked again and there is only the v0.7. one...?
how do you change the com port? anyone???

[SouthPawPaul]

You can change the com port that the ftdi sits on.

Try this guide.

haha.. was easy in the end..! just click and type the no. in.... hahaha

this is a quick screen shot of no hops @ 459 with 3 scans...
using a 433 antenna on rx :/ but can do better tests if this is working....

simon.

[phibin]

can you post a screen shot of your results?
then i can compare...??

thanks,

simon.

Sure thing :)


This is the 459Mhz FW using all of the accepted defaults for header and frequency hopping.

[thundead]

guys, just to make it clear to everyone, the rf module could still emit if its "fried" but at a much lower power thus drastically decreasing range :)

[phibin]

this is the screen shot from....

V2 tx flashed 3.6FW @459mhz 6ch hop fpvuk 459antenna
v2 rx flashed with analyser FW fpvuk 459antenna

any ideas?


just checked on 3.6flashed v2 rx and lots of red light action :(

simon.


graph from v2tx i just purchased..


this is the graph from the v2tx that i flashed with 5v...
looks like they are both f**ked then...?

also attached FW flashed....
