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

[phibin]

hmmm i get at least 400m through granite and with 6ch hopping and 433 antennas on 459mhz so someth is not right.

so 2v at that distance is not good then.....?
i looked at southpawpaul's graph again and it shows an rssi value of '233'..
im getting 230 on single ch now...

do you mean check the tx rf module?

simon.

[thundead]

check both tx and rx modules for bad solder joints.

2v is good still. The system should get bad under 1v (glitchy servos)  and unusable under 0.5v. in theory anyway :) Anyway I''m off to bed now. I'd say leave it for now until I get the new fw out (eta 1 week max) and if that fails you could send the thing to me so I can compare with my system.

Mihai.

PS: who wants to be beta tester (will do range tests, stress tests etc) drop me a PM.

i will test anything... just tell me what to do... lol

also i will do a propper range test in a field and see what results i get with single ch 459.
may also try a test at 433...?

thanks again for your help,

simon.

No posts for a fortnight ?

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

Well this seemed to bring out the woodworm !!!

[thundead]

right POLL for all users:

1. How many AUX channels are you using (ex. CH5 and pan tilt on 6/7)
2. How often are you using them ?  (ex. I can't stop panning !!! :) )
3. How many have servos connected ( just my pan servo which I love to pan )
4. What resolution you think is needed ? ( ex. think 100 clicks is enough)
5. Video tutorial for flashing ?
6. How much pain is the Arduino IDE for you ?


Advanced (answer only if you know what i'm talking about)

5. What latency is acceptable for your flying ? (ex. 20ms  / less for helis)
6. Should the new fw refresh the channels ? (ALL - parallel / One by One - Serial / Pairs (1st 5 ch) + aux
7. how important is hopping on more than 4 channels
8. Do you use Serial PPM ?
9. RSSI  ? (Analogue (sig strength seen by rf chip) / link quality (packet based) / both )


hopefully i didnt forget anything lol :)

Cheers
Mihai.

@ Mihai,

Start a new thread with poll attached, easier to see the results.
People can make a short explanation, as Papa did above if they feel the need to expand/clarify on their reasons for their poll/vote.

everybody look ^^^^

Don't see a poll to select options?

[thundead]

well its not an actual poll as soem questions dnt have fixed answers :)

i dont know how much you will value my input but here goes....

1.  1234 then 567 are a must really...
2.  A lot really... mode/osd/aileron or other...
3.  567 will have at least 1 servo normally maybe 2 dependent on airframe, and osd/mode switches camera gimble..
4.  resolution... more is better??
5.  the video tutorial... well after my recent f**k ups i was thinking of doing one now i know how.
6.  IDE? if you mean your cool little programme that writes it for you... its ace!

B

5.  for me flying multi's the faster the better really, for fixed wing stuff you can get away with it a bit i recon
6.  dont know cant comment
7.  dont know cant comment
8.  nope not tried it...
9.  RSSI is an awesome feature! but a packet quality rssi could be good? can you do both? or switch in the script?

well hope it helps a little?

I'd have love to have flown in the last couple of days however, after being made redundant a fortnight ago, all my daytime is spent job searching.

[Technoweenie]

Finally got my head back in to FPV. Weather has been too nice of late and the latest toy soaked up my time (Triumph Tiger 1050 bike).

So, I loaded up 3.6_Final on the boards and had a look. Everything seems to work out fine. Set the configurator  to hop 3 channels (5,15,25) which should give 433.3 433.9 434.5 which is in the middle of the Canadian digital section of 70cm band. When I checked it out on the RF Explorer Spec Analyzer, it appears that it is hopping the correct 3 frequencies as well as the carrier of 433.000. Is this by design or a bug? Not really a big deal as I can adjust for it. Tried no hopping and it worked out fine as well. If all goes well I can ground test tomorrow for range. I'll use stock whip on RX and Diamond UHF on TX. I also might try the Moxon Rectangle on the TX and the crosshair dipole on the RX horizontal. I'll report back with results.

B.T.W. Excellent work on the code @thUndead !!   :)

Hi :) if you included channel 0 in the ch list then it will go through the base ch as well :) looking fw to your range test

[Technoweenie]

Well I should have known better... spent half a day messing around trying to get the RSSI working. Voltage kept jumping like a bad connection or cold solder joint. Triple checked all connections, resoldered right back to the ATMega chip and still nothing. Long story short... the stubby antenna was feeding back into the board and causing intermittent readings. Put the cross hair antenna on and rock solid.

THROW OUT THE STUBBY ANTENNA!! NOW!!

Oh well, I should have know better.

As for the channel hopping, I don't have Ch 0 in the list. My list is just 5,15,25 giving me 433.300, 433.900 and 434.500 for hops. Strange??

Here is my config.h:

//###############################################################
//### Config.h Generated with thUndead's openLRS Configurator ###
//###############################################################

//####### TX BOARD TYPE #######
// 0 = Original M1 Tx Board
// 1 = OpenLRS Rx Board works as TX, reads your PPM signals from first servo port.
// 2 = Original M2 Tx Board
// 3 = OpenLRS Rx v2 Board works as TX, reads your PPM signals from first servo port.
#define TX_BOARD_TYPE 2

//####### BOOSTER #######
// 0 = No booster
// 1 = Booster
#define BOOSTER 0

//######### Band Select ##########

// 1 = 459Mhz
#define BAND 0

//######### TRANSMISSION VARIABLES ##########
#define CARRIER_FREQUENCY 433000  //  startup frequency

// 1 = Enabled  0 = Disabled
#define FREQUENCY_HOPPING 1

//###### HOPPING CHANNELS #######
#define CHNO 3
static unsigned char hop_list[10] = {5,15,25};

//###### RF DEVICE ID HEADERS #######
// Change this 4 byte values for isolating your transmission, RF module accepts only data with same header
static unsigned char RF_Header[4] = {'3','o','y','n'};

//###### SERIAL PORT SPEED #######
#define SERIAL_BAUD_RATE 115200 //115.200 baud serial port speed

Using a V2 board into a Remzibi OSD. Test results soon.

No action here for a while, am I right that nobody with olrs has flown in the last week with all this perfect weather?

Cmon guys I got an 8km pb on Tuesday and still had 55 rssi! Oh that was on 5.8 video too

Would be great if someone else could report success too

Was on holiday for last week unfortunately, Got a problem with motors on my plane currently but will try and get sorted to do some more range testing though. Think i might need a new video rx antenna to get enough range to fully test the openLRS though :P
