Radio Name

[Friz]

Hi Milke...

a little problem more... maybe i'm doing something wrong:
i need to change local radio name. I do:

discovery.enumradios[0].name := 'xxx';

but delphi says "unable change local radio name".

the same errore if i try to change radio name in many other ways (for example: OBEXClient.Bluetoothtransport.radio.name := 'xxx'.

Am i doing something wrong? 
Thank you.
Davide

Good day!

You are doing all correct, it is windows doing incorrect. The problem is: you have MS bluetooth drivers installed and has not access to registry. I am working on this problem. The problem is how to allow access to this key and all subkeys for application:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\BTH

It works is you have Administrator rights and open full access to that key and all its subkeys to administrator (by default only SYSTEM has that access).

I've seen in the registry the keys you are talkin about, but in all that keys i cannot find the current name of my bluetooth radio! In no key. Is that normal? And, i've done a search in all the registry, to find out a key wich contains my current radio name, but i couldn't find anything! boh in all computer i cannot find the place where radio name is stored...

And, i have admin rights! I don't understand why your vcl say it cannot changes radio name...

[Mike Petrichenko]

Sure you will not find it if it the same as your PC name (by defualt). But when you change the name it appears there (also it call one undocummented function to allow driver re-read new name - but which one - is a sicret

  ok... so what can i do? I have admin rights but i still cannot change radio name... i tried with 2 different computers...

thank you

[Mike Petrichenko]

[Friz]

Sure! No really hurry... i'll come back reading post in some days...

Nice work Mike... 

Ciao,

Hi Mike! Any news about changing radio name? I tried in a lot of ways to set correct rights in the registry but still nothing happens (i get always the same error). But i added my user in rights of ALL the keys and subkeys of HKEY_LOCAL_MACHINE\SYSTEM, with FULL ACCESS. I added "Everyone" user too, with full access, but i still get the same error...

Have you any suggestion more?   

Thank you a lot...

Good day!

Yeasterday I have foudn the real reason why it does not work. That is because on the some PCs it stored a bit different than on my. My (and some others) windows store this information under the key with dongle MAC. But on others it can be not a MAC but some other value. And how to find which value for which MAC i do not know yet But will do soon

I do not find the place where she stores the name.

Thanks.
