Re: [PATCH BlueZ 1/2] adapter: Be able to use ConnectDevice for discovered devices

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi Paul.

Should I submit new patch with fixed commit message text?

For the testing part:

Precondition: have the linux BT adapter (DUT) ready and some remote device you want to connect to

Steps:

- make remote device discoverable
- scan for devices on DUT: bluetoothctl --> scan on
- wait until the remote device pops out on dbus interface
- connect to the remote device using Adapter1.ConnectDevice

To do this you can use these commands:

LE: gdbus call --system --dest org.bluez --object-path /org/bluez/hci0 --method org.bluez.Adapter1.ConnectDevice "{'Address': <'00:00:00:00:00:00'>, 'AddressType': <'public'>}" BR/EDR: gdbus call --system --dest org.bluez --object-path /org/bluez/hci0 --method org.bluez.Adapter1.ConnectDevice "{'Address': <'00:00:00:00:00:00'>}"

For example if remote device emits LE advertisements with general discoverable flag set and the flag "BR/EDR not supported" is NOT set calling reqeuset Device1.Connect would result connecting on BR/EDR transport bearer.

BR,

Simon

Dear Simon,


Thank you for your patch. In the commit summary, an alternative to “Be able” could be “Allow”.

paired device (e.g. use LE transport for dual mode device).

Could you please elaborate a little more? Maybe even give an example, how this can be tested?
