Bind on startup setting

Bind on startup setting was created by rasqba
Hi, is it possible to set the Devo7e to bind on startup, using the DSM2 protocol? I have a model with a receiver that needs to be bound every time I power it up, and was looking for an option to do this. I know it is possible with other protocols, but couldn't find an option to do this in DSM2 protocol. Thanks

You should just have to delete the fixed ID but I've never had an auto-binding DSM receiver with devo before.

Already tried using no fixed ID, but didn't help

Hm, what happens if you set a hard TXID?

Same, have to bind every time I power the receiver. In fact, it goes into binding mode as soon as I power it up.
Its this one: www.banggood.com/2_4G-8CH-0_5g-DSM2-DSMX...62.html?rmmds=search

Thats why would be awesome if I could set the devo to bind on startup, like with toy protocols, but I can't find an option to do it with DSM2

Just checking since TXID is a relatively new thing... You choose an 8 character hexadecimal string and added it to your hardware.INI file?

This is my hardware file from my U7 so you can see where you add the line. Dont know if this will help you but having a fixed TXID seems to take care of all sorts of binding issues people see.

Actually I didn't know about this, I thought you meant the Fixed ID in model menu. Is this feature present in the 5.0.0 stable? If it is, it didn't help, I tried it just now. But I don't think anything might help since the receiver is going into binding mode as soon as it is powered up. Thanks for an idea though :)

It doesn't help. TXID already has fixed unique value, but hardware.ini allow to use custom TXID.

Do you power on TX first? Many small factor DSM receivers go to bind mode (over about 5 sec) if TX powered off.

Yup I power the TX first. And the receiver goes into binding mode straight away.

What model and receiver is it? There's no instructions provided on the receiver to save the bind? Binding is a separate step in DSM because it's expected the receiver will save the bind information. The protocols that "bind on startup" don't really support binding as in a hobby protocol. That's why the button says re-init for those protocols.

If a txid value is set in hardware.ini then that value is used instead of the MCU serial number to generate bind information. It's used to allow more than one transmitter to control the same aircraft without re-binding. It has no effect on whether a receiver will bind or not.

Hi hexfet, it's just a custom micro quadcopter, with this receiver:
www.banggood.com/2_4G-8CH-0_5g-DSM2-DSMX...62.html?rmmds=search

As soon as I power it up, the receiver goes into binding mode indicated by fast blinking. I don't see a possibility to save a bind

Don't see any documentation available. The only review contains "... whilst binding, which is made easy by the push button ...", but I don't see any push-button in the pictures of the receiver. No push-button? The reviewer may have just typed something to get some points?

What is the "DSM" output format? Does that mean it connects as a satellite? Is that the version you have? If yes to the last two, have you tried the satellite binding procedure for your flight controller?

Recommend you post a question on the banggood page, or contact them in online chat.

Yes to the last two, and actually a really nice idea, I will try the sattelite binding procedure now.
And about the review, I think maybe the reviewer meant the bind button on his transmitter? The receiver certainly doesn't have any push-button :dry:

So if I understand correctly, there is no option to set the devo to bind on startup using DSM2 protocol?

Edit: just tried to bind it like a sattelite, no difference. Still enters binding mode after powering up immediately ;/

Edit2: Now I see someone posted the same problem in the banggood questions, so at least I know my receiver isn't faulty

The Devo and Flysky protocols do "bind on startup" if the fixed id is set to None. It might be possible to change the DSM protocols to have that behavior.

Can you check if you can bind to the receiver when the fixed id is set to None? What tx do you have? The code is slightly different for 7e.

Yup I can bind no problem with Fixed ID set to "None". I have a Devo 7e actually. Thanks!

I've added dsm_autobind to the test build section. If the fixed id is set to none, the protocol will enter bind mode at startup. Please give it a try.

This build is based on the current nightly build code.
