Same error. It may happen as you leave the "Change Grip/Order" menu.

I seem to have found a solution. https://github.com/Poohl/joycontrol/issues/4

Troubleshooting

3. If you loose connection immediately when leaving the pairing screen, now try with the -r option (keep the pairing) and see if you can get a connection on the home screen

automatic reconnection prototype worked with https://github.com/formatcom/joytransfer

Hey, I am really desperate and having the same issue. I'm running this:

sudo python3 run_controller_cli.py PRO_CONTROLLER --nfc "/home/user/Downloads/Cards/biskit.bin"

It pairs, but as soon as I press A, it gets disconnected with exactly the same message as OP. I've tried to then CTRL+C and run the same command with -r auto at the end, doesn't make a difference.

Joytransfer works, but it seems I can't set NFC using it...

Is there any noob friendly way to get this to work? I just want to scan amiibo cards.

Troubleshooting

1. If you loose connection immediately when leaving the pairing screen, now try with the -r option (keep the pairing) and see if you can get a connection on the home screen

UPDATE: I can confirm this works. I wasn't doing it on the home screen. Might take a couple of attempts.

There is another way to try.

Run the pause command before the operation that causes the disconnection, and then run the unpause command after the operation is completed.

I found this mentioned here. #4

Pause input

If you get consistent disconnects in some situation do the following:

0. [If you want it fixed]: install tshark and run tshark -i bluetooth0 -w output.pcapng while it happens (started preferably before joycontrol). Submit an Issue with the file (eg on Gdrive) and output of bluetoothctl show while joycontrol runs.
1. try to issue pause just before it happens. This will stop any input and usually prevents disconnects for 10 seconds. But you have to unpause within those 10 seconds, else the connection times out.

My English is not good, forgive me for using translation.

It worked! Thx a lot!

Neither of these work for me
