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

[thundead]

Final thUndead Firmware for the openLRS

Changelog:

- v2 RX Pinout reverted back to 3.1 (RSSI on pin 8)
  -RSSI is not rock solid as it was before
- Serial PPM on pin 9
- Hopping algorithm and recovery improved.
- 459 should be nice and reliable (tested 3km on ground)
- 433 should be even better
- Fixed nasty frequency change bug in GUI
- added channel selection dialog in GUI

DISCLAIMER
- Use this fw at your own risk. I cannot be held responsible for plane crashed, exploding rx/tx modules, aliens making contact etc lol.
- big thanks to papa_lazerous and ghost2212 for bothering to test out this new fw.


Background data

- Ground test was carried out on the 459Mhz band
    Was tested up to 3km with some spare rssi left (ground test)
    huge thanks to papa_lazerous for bothering to test this thing.
- rx/tx were stress tested for about 4h without any module lockouts / resets / etc (tx on micro mode in my Faraday microwave oven lol)
- RSSI was rock solid over this 4h period with slight variations (+/- 0.06v max)

so I can say that if this fw is doing weird stuff then you might be doing something wrong. (unless I can reproduce the bug and eat my words :) ) I challenge anyone to prove me wrong hehe.

Nuf said, now go flying :D

  thUndeadMod v3 Readme

Features

  - 9600 baud
  - reliable RSSI
  - in flight Fail Safe
  - Optimised frequency hopping algorythm that just works
  - Configurable hopping channels
  - Range!!!! (3km ground range stock)

  Upcoming feature list for 3.5

  - Diversity
  - Basic Telemetry
  - bug fixes if any


  RSSI - 3.2v = Max rssi / 0v = fail safe / on PIN 7

SERIAL PPM - PIN 8

In flight Fail Safe - just hold the tx button presed until you hear
                        a long beep and that's it


  Hopping Channels - you can chose how many channels the system hops.
                     less channels = faster recovery times but
                     less interference protection


please post any bugs so I can make the necessary changes :D

FW ready for the grabbing :D

[Coyote]

Excellent work, tried it out, exported all the configs, works great :) Im very impressed

[thundead]

glad to hear that :) Added a poll in there as well just to see what ppl think of the thing after flying it.

[phibin]

oh great stuff!  ;D

cant wait to have a play with the new fw

thanks!

[Technoweenie]

Awesome Work!!  ;D :P

Small token sent to the RedBull / Pringles fund!! May it power many more nights of programming goodness.

[pk-surfing]

Thanks for this Thundead, I'm going to try it out this weekend

ok it's 8am I am just finishing off coffee and toast, I have just got all my gear ready and once the girlfriend has gotten herself ready for the off (could be minutes or hours, strange creatures are lady folk) I will be commencing operation range test to see how stable it is.  Will report back in a few hours:)

[thundead]

Cheers  :) added u to the hall of fame :D

Stupid question, in pre config options it has Header DoMo, whats a header ?

[papa_lazerous]

Stupid question, in pre config options it has Header DoMo, whats a header ?

It's important you change the header and make sure you have the Tx and Rx the same as each other.  The 4 characters in your header are a way of the Rx and Tx knowing to listen to each other.  If a packet of data doesnt have that header then it will be ignored

[thundead]

Couldn't have said it better myself :D any news from the range test ?I'm gonna do my own in a couple of hours down @ the beach :)

[papa_lazerous]

Just done some basic range tests along my street in low power mode (10mW) 

First off I flahsed the FW with no hopping as a bench mark, I walked to the end of my road which is only 200metres and i had great signal with no glitches.  I observed the RSSI to be consistent, in that it went down in a linear fashion as I was walking away from the Rx and didn't jump around.

I then proceeded to goto 3 channel hopping and did the same test, also got to the end of the street with no issues,

I then ramped it upto 6 channel hopping and got to the end of the road but had a few hiccups, I was at the end of my signal but it seemed robust enough to hop past bad channels and I think I could certainly fly like that if I had to.

I live in a tree lined street and we know 459Mhz is a band thats absorbed by big dense trees and I was only in 10mW micro power mode so I am pleasantly surprised to be getting that range.

Next I am going down the park to test 6ch hopping @100mW  previously my ground range was only 430metres on 100mW so hopefully I will exceed that.

I will report back later with full results
