Support for selecting presets and PEQ

[NotReallyADeveloper]

This is exactly what I was looking for...thanks for engineering the solution!

Looking quickly at the code, it seems selecting presets and PEQ are not supported yet (app functionality that exists for the SB3000 and likely other models).

Is that because that isn't exposed, or rather because it's not supported when using the SB1000?

I can try to figure that out for myself, although as an unskilled / part-time coder, it will take me a while to figure out what you've done to get close to that.

Am attaching what is exposed when using a BT discovery tool with the SB3000.

Hi. I'm glad you like my project. Presets and PEQ are not supported because I don't usually change them, and to port a new functionallity to the python version takes a lot of time and tests. In this case, even more because I would need to implement the filter preview on the gui. I don't discard to look into it in the future.

To discover what a function does on the svs app, you first need to enable developer settings in an android device and then enable bluetooth log. Then you use svs app to change the parameter you want to investigate to some specific values. After that, you copy the bluetooth log to a computer and import it in wireshark to see what the parameter is doing on every bluetooth frame (how the values are encoded). Once you know this, all you have to do is write a function to do the same in python.

In your screenshot you show some services of the subwoofer. 99.9% sure you don't need any of this to.implement peq and presets. Once you subscribe to the 'parameter exchange' UUID you will send to it whatever parameter you wish to change (volume, phase or peq and preset changes). Bye!

Thanks for the extra info. TBH I'm more interested in the commands and protocol syntax than the GUI (I would repurpose as a bespoke gateway for IP control).

I'll also have to find an android device as that's the one platform I don't have access to - unless I can emulate.

Good. Let me know if you find something interesting :)

While I try to find out myself on how to do this, would it be helpful if I resubmit as two separate requests?

1) As a user who has set up different presets and EQ curves, I would like a way to select preconfigured settings through pySVS; 2) As a user with a fully automated audio system, I would like a way to read and write SW settings via the command line or API (TCP or Web-based).

[logon84]

Point 1, I will look into it in a near future. Point2, as the sub doesn't contain a IP stack in it, is not a matter for this project to write one. You will need to write it yourself the way you want. Writing a command line mode will be doable tough by just opening every function on "GUI routines" section to accept parameters on the command line.

This is what I've been able to capture over open air for presets (ended up getting it to work with iOS and PacketLogger):

I can otherwise start testing your app later today on a different model sub...first, where would one find the MAC address of the sub(s) for the script to work? It's not visible on iOS, Windows or Mac standard functions, and it's not even on the sub itself (which I find odd).

[NotReallyADeveloper]

Got the MAC address via another method and gave the app a whirl...perhaps more than the MAC address needs to be changed as the interface didn't show any preset values, nor did the sub accept what I set.

Here's the bleak debug w/ MAC Address redacted:

It seems to me that there is a problem with bleak module. I cannot do any test right now because my sub is on svs technical service. Try downgrading module to version 0.14.2, because it is the version I have installed on windows and pysvs was working ok with that version. Bye

Try downgrading module to version 0.14.2, because it is the version I have installed on windows and pysvs was working ok with that version.

Downgraded. Same behaviour (connects, but seemingly gets no response to ASK commands as debug shows nothing and GUI doesn't change).

I don't know what is happening....Until I have my device back, there is not much I can test. Try maybe with a live linux to see if it works.

[NotReallyADeveloper]

I'll try again with my mac, but as I recall, it was the same behaviour.

(Sorry about your sub, too :( )

[logon84]

Did you try again with your mac? If still not working, can you try with version 2.6? (I still don't have my subwoofer) Also, I am interested in windows version visible on "msinfo32", python version and output of "pip list". Thanks
