DSM2 Reports

I`d like to have a topic where all the DSM2 bugs are reportet.

I tried this Receivers

Orange 6CH
Orange 9CH
Spektrum AR6200
Spektrum AR8000

all with and without Satellite
and tried all with or without fixed ID

After Binding all seems ok, Leds on Receiver and Sat are solid.

After Power down and up again (first Tx then RX) the Leds are blinking like after a brownout.
If i power up first RX then Tx all seems ok.

With my AR8000 and with my Orange 9CH Rx i cant get more then 7 Channels to work.

Blade MSR an MCPX looked fine.

Hi all

same for me like described by Werner,
additional i have tested with and without flybarless systems,
with the same result.

Maybe Erazz (the programmer of ER9X)can help you out with some logs.
DSM2 with serial protocol of the TX Boards is implemented sucessfully in ER9X

How can we do these logs for you??
Which hardware is needed

I don't know if you are aware of what is causing this problem, and I'm sorry if I'll write something you already know, but by documentation the problem seems to be related to binding ID code.
What I've read elsewhere is that the DSM2 binding (and GUID used in others messages) is done with a TX ID (fixed) + a Session ID (random?).
The Session ID is renewed at each TX power ON, and accepted (and stored) by receivers.
This method is used to signal to the user a possible power loss event/problem:
the receiver at power ON can distinguish if it was working on the same previously used "TX session" or not (that is: the receiver has been switched OFF and ON while the TX was still ON).

So, as explained in your code docs:

The bind packet is as follows:
aa bb cc dd aa bb cc dd eeee ff gg hh ii jjjj
aa : 0xff - mfgid[0]
bb : 0xff - mfgid[1]
cc : 0xff - mfgid[2]
dd : 0xff - mfgid[3] + offset

And:
The GUID is equal to the inverse of bytes 2-3 in th ebind packet

So I think it can be possible to find a solution with a small brute force exercise here, trying to change a bit at a time of the GUID.
Maybe... Just a clue.

Maybe Hammer22 could help again.

He implemented 9Channel DSM2 and 8Channels and more DSMX on his modules.

Thank you so much for your help.

Is there a way to donate a few bucks to help out with some needed hardware??

one issue i noticed last night when i hooked up my first orange dsm clone to deviation is the stick modes are wrong or something not sure what it is...i fly mode 3 but had to set it to mode 4 and plug the Elevator servo into the throttle channel and the throttle servo into the Elevator channel in order to get it to work properly...not sure how this could be fixed but might be worth checking into...seems that mode 1 and 2 were correct if i remember rite...

Once I have a 9ch Rx, I'll work on getting it functional. I already have enough logs to do that I believe.

Just a short question, if I may: Is it likely that you are going to fix the binding problems of the orange satellites connected to Tarot zyx-s along with your work on the 9ch DSM2?
I guess a lot of users, me included, are waiting to have this work on their helis or copters.

the Devo is EATR but DSM is TAER.
so you need to make sure the channels are properly ordered. if you start with a Devo config, and switch the protocol to DSM2, you'll have all the channels in the wrong places.
The Mode setting has nothing to do with the protocol, so it is unlikely to be related to what mode you fly. at one time mode3 and mode4 were incorrectly set, but that was fixed for 1.1.2

yes when i selected a new model file it started as Devo ...so i just need to reload the template? i am setting this up on a Tricopter so i wont need the 6ch heli template just 6ch would work...

thanks a bunch i'll give it a try and see if it works...

i selected the 6ch airplane template and it fixed the stick mode issue i was having but now when i turn on my tx it has a safty box pop up and say ch3 is at 50% saftey is -100% ...

any idea on how to fix this?

look at the [trim1] Section and insert/replace
this: [safety]
Auto=min

cheers
Graziano

in the model file? it has no [safety] so i need to add it to the file? if so wouldn't i have to do this for all the model files? ...that could take a while..
