If i am not mistaken v1.3.1.59, will check and come back report.

Thanks for now.

Success!


I put the final touches on my DIY MPM Lite today and tested it out.
SUCCESS!!

I was able to quickly bind to a cheap FrSky clone RX I had on one of my wings. EVERYTHING worked!

I am using a highly trimmed down protocol set due to the 64K FLASH on the Blue Pill I am using.

I attached a couple photos of this little messy rig.

Now all I need are a couple cheap little Quads I can buzz around the house with. Any suggestions?

Breadboard solutions are always so much fun

How cheap is cheap? Right now the Newbeedrone Hummingbird brushed is like $48 and people are raving about how well it flies.. They have a brushless one for $80 thats great value too. Alternatively there is the Mobula6 which has been one of the most popular quads this year, which is $85 or so... $120 for the HD version.
Or if you go even cheaper i can give a parts list for one you can put together for about $30, if you are ok to wait on the parts from China

Thats all FPV quads btw, if you want a line of sight quad then there are all sorts of cheap and nasty quads on Amazon etc from like $15

Yes I am using the latest version. The release 1.3.1.49 is also lagging. It must be something else.

Pascal, i wonder if you have any ideas on this. I have 2 Mobula6 quads, using SPI Frsky receivers ("compatible receivers"), in D8 mode.

They are bound to my Jumper T8SG, and show around 80% RSSI (I have bound them separately), but using the same 'model' in Deviation
On my DIY Multiprotocol, I have set up a model that uses Clone TX protocol for D8 mode
For the first one i did fine tuning, turns out 0 was the halfway mark
For the second mobula6. the halfway mark was -36 (-78 to +6)

Shouldnt they have the same fine tuning value? Since the receiver should be doing the fine tuning to match the Jumper TX (which is the same for both)?

The only thing I can think of is that these RXs don't do auto tuning.

Thanks and that might explain why some people have horrendous range with these quads. If they had Frsky radios they won't be able to fine tune either

Thank you.

I have add my experience in :https://github.com/pascallanger/DIY-...ule/issues/398

Thank you for your help. I can test somes solutions if you want.

Traxxas Aton with Multi-Module?


Hello,

I saw that there is support for Traxxas surface vehicles, but couldn't find anything on using Multi-module to control the Traxxas Aton quad.

https://traxxas.com/products/models/heli/Aton

Does anyone know if this is possible?

Thanks,

Larry

I see 2 different issues posted in https://github.com/pascallanger/DIY-...ule/issues/398 . It starts with the RX going to failsafe time to time to you where there is only telemetry issues.
The lose of connectivity is really strange and I have no clue. For the telemetry, I would think it's a timing issue.
Therefre, you can try to to change the values on these 2 lines:
- return 1700: https://github.com/pascallanger/DIY-...a7105.ino#L402
- return 2150: https://github.com/pascallanger/DIY-...a7105.ino#L413
The sum must always be 3850=1700+2150. So if you decrease by 100 the first return from 1700 to 1600 then you need to increase the 2150 to 2250 so that the sum stays 1600+2250=3850.
What I would do is to decrement 1700 by step of 50 (incrementing the other one) and see if it helps the telemetry.

You can have a look at the TX and which RF component is in use (a picture of the area where the antenna is connected). After depending on what is there, there are multiple options but all points to you to help reversing the protocol by doing dumps and spending the time to do so.

Thank you Pascal,

I will try it next day.

Can you confirm that this _Config.h file is setting correctly for this config : https://downloads.multi-module.org/?rmtx16s

Thanks for explanation of the process.

I've recently bought a Eachine Mini Mustang which uses the V761 protocol.

I'm stumped by a couple of things:

1. After binding, throttle does not work, but other control surfaces do work and respond to stick inputs. It's as if the throttle is locked, but moving the throttle stick up and down does not unlock it. If I switch back to the cheap stock radio that came with the mustang it works fine.

2. I set up channel 6 for calibration, in which I just toggle between -100 and +100 when the switch is thrown back and forth (taken from the V761 documentation: https://github.com/pascallanger/DIY-...s.md#V761---48). However, when I try this out, the radio is disconnected from the plane, and I have to unplug battery from plane, and back in again to re-establish link to radio.

I'm running the latest precompiled firmware (v1.3.1.59) for stm32 (iRange Plus).

my guess is you need to adjust the trhottle throw and trims

on one of the mini rx i got, this was the issue

see here :

the last post may help you if the earlier "trick" doesn't
