Switch FW 15.0.1 breaks compatibility

[Anercomp]

Stuck at connecting to the Switch again.

[blueapple128]

Cannot reproduce; I'm on Switch FW 15.0.1 (on a completely vanilla Switch) and NXBT works fine.

[TeoMM]

@Brikwerk would you mind confirming this works on 15.0.1? Tested it now for the first time and it doesnt show up in the switch controller menu., yet the bluetooth manager says every other second that it connected and disconnected right after.

Also, are you aware if it works on VMWare?

[blueapple128]

I have seen the "repeatedly connected and disconnected a second later" behavior frequently, but only when making hack changes on my end such as trying to get it to work on a non-headless VM, or trying to manually change the VM's USB filters, etc. I don't think I've seen it when following the original instructions. I've done some vague, incomplete troubleshooting and I think the reason has something to do with bad drivers or some incompatible(??) apt install at some point in the past.

If you're on a non-Linux machine, try destroying the whole VM and recreating it; does that do anything? If you're on a Linux machine, does it still happen if you try booting off of a live USB?

[TeoMM]

@blueapple128 should i rather install linux on a laptop and try it that way? i've reinstalled ubuntu in VMWare multiple times.
The apt install is also quite vague as i had to install multiple old(er) packages mentioned across this thread for this to work which were not mentioned in the original documentation.
Would you mind taking things on discord chat if it gets rougher?

[blueapple128]

I have never tried using NXBT with VMware. If you have a spare laptop to install Linux on, then sure, go ahead.

[TeoMM]

managed to get it working on an actual ubuntu install, BUT
same exact problem as #39 #94
@way-huang @WilsontheWolf @blueapple128 @AsinineLucky
Did you manage to get it working?

[blueapple128]

After pairing once, does reconnect work from the home screen?

[TeoMM]

@blueapple128 nope, doesnt work. I've tried doing that, disconnecting the controller first from the pair menu and then trying to connect from the home menu, restarting the console mid- connection and hoping it'd reconnect. nothing seems to work.

[blueapple128]

Some questions to clarify what's going on:

• After connecting for the first time (seeing the new controller show up on the pair menu), can you make inputs before exiting the menu? (And then the controller immediately disconnects after exiting the menu?)
• From the home menu, what command are you running to reconnect?

[TeoMM]

@blueapple128

1. Yes, i am able to make inputs, the Switch is making the corresponding sounds when pressing the keys in the webapp.
2. I lately pressed 'shutdown controller' before leaving the menu so as not to disconnect by itself when leaving the pair menu, and then starting up the app again to pair it AND tried to 'restart controller' (3rd button on webapp) but it won't pair again with the switch from the home menu.

[TeoMM]

@blueapple128 can you confirm Python version? I am using 3.10

[blueapple128]

1a. Not sure what you mean by "corresponding sounds". Pressing stuff like X/Y/L/R after pairing should all make the same sound and the controller icon should pulse once. Pressing +/- should bring up a help screen (and pressing A/B should exit the pair menu). Does this match what you're seeing?
1b. I am using sudo nxbt test to pair for the first time, not the webapp. Does this work for you? If not, does it output anything interesting?
2a. I have never tried shutting down or restarting the controller from the webapp. Can you go to Settings -> Controllers and Sensors -> Disconnect Controllers (to see how many controllers the Switch thinks are paired to it)? Does this number increase by 1 after pairing?
2b. Can you try reconnecting from the Python API instead of the webapp? Try this:

import nxbt
nx = nxbt.Nxbt()
controller_idx = nx.create_controller(nxbt.PRO_CONTROLLER, reconnect_address=nx.get_switch_addresses())

Does this output anything interesting?
3. I am using Python 3.8.10.

[TeoMM]

@blueapple128
RE:
1a. That's exactly what i'm seing. Any other key(Besides A,B, + and -) make the same clicking sound once when pressed. + and - bring out the help screen, A and B get me out of the pairing screen and result in controller disconnect.
1b. i did the same
2a. it was 2 joycons that i already had connected as my personal ones, and whenever i connect the emulated one it's coming up as the same one, only sometimes a different color.
2b. will do now
3. i switched to this version now to make sure the problem isn't coming from python 3.10

lmk if you'd be interested to join a voicecall anytime soon, i'd be really glad if i could get some real-time help on this

[blueapple128]

2a. What do you mean by "the same one"? Does the number increase from 2 to 3 after pairing?

2b. What is the output of this command?

1b. Unfortunately, as Brikwerk said in issue #39 it may be an OS scheduler or even hardware issue, in which case I wouldn't be able to do anything to help. I'd open a new issue with a different title alongside #39 and #94.

Another set of commands to try:

# Go to the unpairing Switch menu and disconnect everything so the number goes back down to 2
# Go back to the Change Grip/Order screen
# sudo python3

import nxbt
nx = nxbt.Nxbt()
ci = nx.create_controller(nxbt.PRO_CONTROLLER)
nx.wait_for_connection(ci)
nx.get_switch_addresses()  # What does this output?
nx.remove_controller(ci)
nx.get_switch_addresses()  # What does this output?
# Exit the Change Grip/Order screen with the touchscreen or whatever
nx.get_switch_addresses()  # What does this output?
nx.create_controller(nxbt.PRO_CONTROLLER, reconnect_address=nx.get_switch_addresses())  # What does this do?

[blueapple128]

Just to confirm, the whole process (unpair-connect-reconnect) still works on my end after updating to Switch FW 16.0.0.

[way-huang]

managed to get it working on an actual ubuntu install, BUT same exact problem as #39 #94 @way-huang @WilsontheWolf @blueapple128 @AsinineLucky Did you manage to get it working?

I use a usb bluetooth adapter, it works fine. It looks like the laptop builtin bluetooth has some peoblems.
