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

[thundead]

ooh man u can't imagine how good that sounds considering ppl have been having problems with their setups. Guess I'm doing someth right afterall lol :D

I dont use a booster. My new record was some days ago 3100m with a RSSI of 2,2V, i think there is room for more, but the video signal was bad. :)

[thundead]

It has begun :D

[thundead]

new fw almost done :) quick preview:

- fixed RSSI bugs (for good I hope) - RSSI back on pin 8, Serial PPM moved to pin 9
- Hopping and recovery optimised.
- Configurator bugs fixed (the annoying freq change bug etc)
- working awesome on 433 band (459 still has range issues...)

I'm doing a stress test now on rssi and rx to check for rssi dropouts and module lockouts.
ETA 1-2h.

Cheers,
Mihai.

And all that on one pack of Pringles .. now come on, you can't expect us to believe that !

How do you know that 459 still has range issues, is it emitting less power?

[thundead]

at the moment I'm only guessing lol. I did change some things so I hope 459 will be better but have tested only 433 atm. Fingers crossed lol :)

ooh finished pringles ages ago. waiting for pizza now lol.

Nice one bud, did you find anything concerning ?

[thundead]

nope not really. only the channel spacing was way off. changed it and managed to keep the fw on the ISM band as well lol.

thUndeadMod v 3.6 Beta

- Config GUI bugs fixed
- added channels in GUI
- 459 band spacing fix
- overall hopping and recovery algorithm improvement
- RSSI fixed (PIN 8)
- Stress Tested for 4h - no dropouts / random rssi encountered.

NEEDS TESTED!
- 459 range (should be better)
- Serial PPM

------
WHo wants to beta test PM me and I'll give u the password.

Cheers,

Ok a little update :

After the problems I had I started fresh, I fitted a brand new Rx as a TX in my Turnigy 9x, turns out its IMO much easier and better than the flytron TX, everything fitted inside the module case with room to spare. I tested that and RSSI held fine unless I moved the stick fast then I could get it to glitch to 0. This aside it seemed better than the TX installed so I went for a flight. Then I fitted brand new Rx to Skywalker to rule out that as well

1 flight with the Skywalker was fine, very windy so was not fun but landed to have another flight, swapped lipos, then I took off and within 200m OpenLRS lost RC link and Skywalker came down that hard in the wind it was in 7 pieces :(



On review of the video RSSI had started bouncing to 0 again just before I launched ( lunched LOS so had no idea )

Obviously I was not impressed, I can not conclude that its OpenLRS fault entirely because it might be my Turnigy 9x, but I have ordered my Chainlink Rx`s and I`m going to test the RSSI of the Chainlink and see if I can replicate the OpenLRS RSSI bouncing, if not, there`s something wrong

Are you powering the OpenLRS RX board configured as a TX directly from the Turnigy 9x battery ?

If so this might be the source of your problems since the MIC5205 Regulator used on the
OpenLRS RX board can only cope with a maximum input voltage of 6.2V at the maximum
current output of 150mA. If the input voltage is higher then the Current Limit Thermal Shutdown
will be triggered and the RX board working as a TX will lose all power.

See the "Thermal Considerations" section on page 8 of the datasheet http://www.micrel.com/_PDF/mic5205.pdf

I'd recommend anyone using the RX board as a TX use a 5V or 6V supply from a BEC.

In both configurations I had the tx and rx powered from the 5v output of the Turnigy 9x

Where are you getting the 5v from?

The clue was in Coyote's response I will quote it in bold for you

Ok, more specifically where on the 9x?

I thought the module output pins were higher than 5v?

[raptor_flyer]

Maybe the Turnigy 9x has a 5V supply to the RF module as well as the higher voltage directly from the battery ?

On JR and Futaba transmitters the power supply to the removable RF module is usually
the 9.6V (nominal) from the battery.
