Wait for *multiple* devices to connect

[Matsuo3rd]

@toy: thanks for this great tool and making it available to the community.

I know --wait-connect ID is EXPERIMENTAL, but would you consider enriching the feature with waiting for multiple devices to connect?

My workflow is the following: I can connect multiple Sony Dualshock game controllers to my Mac. Once any of them is connected, I am executing some script. I was hoping to pass device name to --wait-connect so it would be triggered by any controller connecting (they are all named "DUALSHOCK 4 Wireless Controller"). But it looks like current behavior is to resolve device name with first device ID found in the "recent" list. Meaning, only one of the controller will trigger the --wait-connect (first one in the list).

So, would it be possible, with an extra flag, to wait for any devices matching a given device name pattern?

` blueutil -v 2.8.0

blueutil --recent address: 1c-a0-b8-a5-4c-35, not connected, not favourite, paired, name: "DUALSHOCK 4 Wireless Controller", recent access date: 2021-03-25 08:15:07 +0000 address: 90-89-5f-0a-f2-0f, not connected, not favourite, paired, name: "DUALSHOCK 4 Wireless Controller", recent access date: 2021-03-25 08:14:47 +0000 address: 90-89-5f-f1-a5-ba, not connected, not favourite, paired, name: "DUALSHOCK 4 Wireless Controller", recent access date: 2021-02-24 20:30:59 +0000

blueutil --wait-connect "DUALSHOCK 4 Wireless Controller" ` ==> Will only be triggered when "1c-a0-b8-a5-4c-35" is connected, not the other ones.

Thank you for opening the issue, looks interesting. Just to clarify, I marked some functionality experimental more to say that the usage is not part of stable api and can change, rather than that it can be removed.

Currently all actions requiring device id when called with name will resolve it to latest device with matching name in the list of recently used, so depending on order of connecting or disconnecting your controllers the resolved one should change. Your case is when multiple devices have same name and this can be handled by replacing device resolution by name, with checking connected device to have the right name.

I came up with following options:

• one more parameter for --wait-* commands to wait for any device by name,
• some specifier for name like any:DUALSHOCK 4 Wireless Controller (but any: can be a prefix for device name too),
• some switch (like --match-all-by-name or something) to tell all commands to work with any device by name.

I'm just not sure yet how to make it not confusing itself and compared to other commands (like for example --is-connected could be also checking for any or all devices with specified name to be connected instead of checking the resolved one). May there be a need to wait for all devices with some name, and maybe waiting for any of differently named devices (like either keyboard or mouse)? --wait-connect, --wait-disconnect, --wait-rssi and --is-connected will probably benefit from all possibilities. For --info, --add-favourite, --remove-favourite, --connect and --disconnect an option for name to resolve to all devices with that name could be good. --pair is probably better left with specifying one device, but while investigating I understood that for a device unknown to system it is not possible to pair with device by its name even after inquiry.

Thanks for considering my ask. I would go with option 3 (--match-all-by-name). It is more clean and flexible.
