install_sound on gen2 not working

[BerraKode]

I've tried to get this working but without success. I get the following message when trying to upload my pack:

---

$ mirobo install_sound http://192.168.0.122:80/image-server/es.pkg d41d8cd98f00b204e9800998ecf8427e 1005

Is it confirmed this does not work on gen2 or could it be I've done something wrong?

Thanks for the awesome work btw!!

Unfortunately the error codes are unknown at the moment, nor anyone has confirmed whether this works on gen2 (actually no one has reported even if it works, I have just tested that it works on my vacuum).

Anyway, seeing that you are not seeing download progress at all, I would look first into your web-server's logs to see if it ever tries to fetch that es.pkg at all. Maybe error 4 is "unable to download" or something similar?

edit: I did some experimentation, error 2 is download error (when I shut down the server during it's downloading it), error 3 is checksum (md5) error, rest are still unknown.

I get this in my webserver log:
192.168.0.148 - - [22/Jan/2018:11:38:09 +0100] "GET /image-server/es.pkg HTTP/1.1" 200 249 "-" "-"

So looks like the error is with the vacuum right? I know at least another guy who got this working on his gen1. So maybe gen2 is the villain.

Ok, may very well be that there's something else we need to pay attention to for gen2 devices, unfortunately I have no answer for this at the moment.

Could you re-try this with the current git version? The previous server did not send a content-length header as part of the response, which caused problems with firmware update status messages, maybe they check for that differently also for the gen2.

Would love to. Will let you know tomorrow!

Unfortunately still the same error message for me :(

https://github.com/marcelrv/XiaomiRobotVacuumProtocol/blob/master/install_sound.md defining the sver for the payload is probably what is needed here. If someone wants to test and report back (or even create a PR), it would be nice.

[BerraKode]

I can only find the install_sound() method (which doesn't have a parameter for sver). How do I use dnld_install_sound? :)

Potentially interesting for this #348 (comment) .
