Add bluetooth battery module

[mahaveergurjar]

I think Adding a feature to show Bluetooth headphone and etc devices' battery show on waybar makes this type of module
show battery at this time but in notification only when device is connecting

but not show on way so add this feature

[kRHYME7]

Wow, a nice feature.is there any way to fetch the battery info in the terminal?

[mahaveergurjar]

yes
first type bluetoothctl and then type info in and then you can see battery in last line

like this type

[kRHYME7]

Nice can you provide the raw test output please I'll try to do some testing. So this is assuming only 1 device is connected right?

[mahaveergurjar]

Yes at this time only one device is connected
you can make scripts so i can tested you script

[kRHYME7]

like this ?

[mahaveergurjar]

like this ?

Yes this type 👍

[mahaveergurjar]

now connect two devices but show only the above device info by default

using device address access any device

[kRHYME7]

no worries this is already a waybar function but said to be experimental

In case a single device without a battery will display only the number of connections ( this is the expected behaviour of the repo)

In case if multiple device is connected ( Only tried on a single device with battery battery )

what else can we display if possible? volume is handled already by the other module. Is thi?s enough ?

[mahaveergurjar]

Yes this is enough

[kRHYME7]

Here you go

"bluetooth: {
        "format": "",
        "format-disabled": "",
        "format-connected": " {num_connections}",
        "format-connected-battery": " {device_alias} {device_battery_percentage}󰥉",
        "format-device-preference": [ "device2", "device1" ], // preference list deciding the displayed device
        "tooltip-format": "{controller_alias}\n{num_connections} connected",
        "tooltip-format-connected": "{controller_alias}\n{num_connections} connected\n\n{device_enumerate}",
        "tooltip-format-enumerate-connected": "{device_alias}",
        "tooltip-format-enumerate-connected-battery": "{device_alias}\t{device_battery_percentage}%"
        },

remember Some device won't declare there battery so sometimes it won't work and may look like this
PinkBuds should have battery but dbus does not detect the battery percentage and same goes the bluetoothctl not fetching the percentage sometimes

bluetoothctl : Sometime not detecting the battery

This might be the reason why this is an experimental feature on waybar.

[mahaveergurjar]

Ok I will try

[kRHYME7]

Can you test connecting to those devices and try what device will be prioritized?

BTW should I add a PR for this ?

[mahaveergurjar]

OK i will test

[kRHYME7]

Additional info:

if you will see a notification plus battery % it is likely to have battery percentage in the waybar too.

Waybar just reads the dbus or whatever that is called too, the same as how Dunst or a notification daemon knows the percentage.
So yes it will be hit and missed. but I also love this feature

[mahaveergurjar]

Yes this will work with both devices
Yes please add PR for this waybar module

[mahaveergurjar]

I think you can add this line this type so see the batter in waybar
"format-connected-battery": " {device_alias} // 󰥉 {device_battery_percentage}%",

[kRHYME7]

I remove % as it looks too long but yes I might consider this as this is intuitive.

[mahaveergurjar]

ok

[kRHYME7]

How about this ?

"format-connected-battery": "󰥉{device_alias} {device_battery_percentage}%",

[mahaveergurjar]

yeah its better

[mahaveergurjar]

[kRHYME7]

Make new

Relating to bluetooth batt ?

Try to post this on a separate discussion so we can just throw this link to new comers and also easy tracking.
