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

[thundead]

well u get more bandwidth on a 2.4 link than a UHF one. just because lol. Anyway working on something interesting atm so any pringles help would be appreciated :D

[ghost2212]

Looking at the Bounce meet posts on RCG it seems that this was not an isolated incident with Open LRS. There are several people all saying the same "glitches" happened on TLRS, Dragon Link etc. It would seem to me that there was just too many people on the same bands at the same time

Remember SouthPawPaul was on 459mhz which as far as we know was completely clear that day, everyone else was using 433 frequencies. I don't think its lack of frequency space but more the lack of the systems being unable to cope with multiple users. They were never designed nor tested with multiple transmitters on.

A friend of mine who was running EZUHF on 433etc had no problems throughout the day.

pig tails arrived :)

more testing soon....

finally managed to do some testing....

unfortunately no improvement at all!!! :(

in fact now I'm losing LOTS of packets on 6ch hop...

i tried it on 459, 433 6ch hop and same results now....
also tried above with 433 and 459 antennas....

i had a quick try with 459 no hopping on 459 antennas....
still getting around the same rssi voltage..

on 459 6ch hop,, between lost packets if i move the sticks i get a brief rssi of 3.2v ?????


i really am at a loss now..
i was so looking forward to it finally working.

i may have a go flashing different fw's and see what happens,
but mightily disappointed now...

if the fw's good, i might just throw it in the bin now..?

i will try make a 'short' vid of the whole process and post a link...

i really want to get this to work!

really really hope its not a hw issue :(

simon.

[phibin]

so did a shortish vid as requested....

http://youtu.be/_hTw-kATM2Q
should be live in about 20mins...

sorry if it drags on a bit but it was quite hard work filming and doing it all... lol

and i cocked up the tx flash with one hand :/
but paused the cam and connected it properly
all flashed AOK

so i hope you can help...

if i missed or didnt show anything enough,
let me know and i will let you know... lol

thanks again for your interest in helping get it sorted :)

Standing by for video :))

[papa_lazerous]

Right I've watched the video and you flash in a completely different way to me! I am at work till 10:30pm but can do a video of how I flash and we can see if you get things working using my method after work. Alternatively I am on Skype right now and if you want I can guide you through what you should be doing, just drop me pm and I will give you my Skype details

I can not see your Rx boards two leds responding to the upload data, I don`t know if that`s just the camera though.

But there is something very wrong, but they go through their frequency cycles but then seem to loose sync

[papa_lazerous]

I have a theory on what the problem is, waiting for phibin to get back to me, its just too much of hassle typing it all out on a phone lol

[phibin]

they go through their frequency cycles but then seem to loose sync

that is just what i thought.....


simon.

pm sent papa..

[phibin]

thanks again for all your help so far guys...!

just ordered 2x rf modules to replace said f**ked ones
and a 3.3v ftdi thingymebob.. so no more magic smoke incidents!

i cant belive i did that! what a stupid mistake!!!
well we live and we learn..

so thanks again... and we wait for the post again :/

It happens, I use a UBS to FDTI with jumper pins to select 5v for wii`s and 3.3v for OpenLRS. Its very good, but the ebay link no longer exists :(

Good of John to offer to fix it for you :) That will save you a few bob

very good!!

i did just think though.. have i waisted yet another 10er?
on the 3.3v ftdi???

dont we flash the processor at 5v 16mhz 328?
this means we flash at 5v for the chip? but rf module needs the regulator so it dosnt fry?
so we plug power rather than using the ftdi power???
or do we use 3.3v to flash too??

sorry if im being a bit stupid... lol

simon.

[Coyote]

Your USB to FDTI takes 5v, but your FDTI input on the Open boards are only 3.3v

You can power the boards via a receiver pack or a bec and have no vcc pin from the FDTI and do it that way though
