Android Question BluetoothAdmin sync

[umberto_dev]

Hello, I have some troubles when I try to scan several BT devices.
First of all, the time it takes to begin the scan seems unpredictable. Sometimes it's almost immediate, sometimes it takes a long time. It doesn't depend on other activities.
Last week I noticed both on my phones and tablets that when I begin to scan the BT on Settings, they recognise Mac addresses at first and then the names.
So my questions are:
- is it possible to start scanning without delay?
- is there a way to manage Admin_DeviceFound when I intercept the mac address, before the full association (Name and MAC)?
Thank you very much for any help.

No. The scanning is managed by the OS.

- is there a way to manage Admin_DeviceFound when I intercept the mac address, before the full association (Name and MAC)?

Yes. You don't need the name. Only the MAC address.

Thank you very much, Erel.
I gave a look at the library XML. The DeviceFound event has two arguments (Name As String, MacAddress As String).
I think that it returns values only when and if both are found. As I wrote it seems that Android makes a mac address search first and then then the friendly name. Is there a way to override it and get the MacAddress only? This way I shouldn't have to wait for the whole process to be performed and I could count the number of devices found faster.
Thank you again for your precious help.

How do you see that the mac address is available before the name?

On Settings (Android Settings). When I start to search for devices it returns almost immediately their MAC addresses, and after a while (about half a minute) it shows the friendly name. It happens both on three smartphones and 2 tablets (several Android versions). If I use BT4 devices, instead, the search is almost immediate and names appear immediately too.
So I was thinking that if I can extend the class and override the method (or event) I could skip the name association, since I really don't need it.
Do you have any idea?
Thank you very much.

It is not possible to only discover the mac address. I guess that the slow part is not the name discovery but rather the services discovery.

Don't know. Since it returns the mac address, a generic bt symbol, and then the name and a proper icon.
I'll try another way and I'll let you know.
Thanks a lot.
