I'm developing an application which will use Bluetooth SPP profile to transfer data to another Bluetooth device. The data rate must above 200kbps, so I want to use DH5 (ACL packet).
When connection is up, I use:
iChgPktTypBuf().iConnH = 0x0001;
iChgPktTypBuf().iPktType = 0x8000; //DH5 packet
iSock.Ioctl(KHCIChangePacketTypeIoctl,iStatus,&iChgPktTypBuf,KSolBtHCI);

but an error occurs after that: "Feature is not supported -5"
so does Nokia support all the HCI command listed in the bt_sock.h or is there a certain list about all the HCI commands Nokia currently support?

Thanks a lot!!

I used HCI commands to query the local address of my bt-device and to set the discoverbility-mode.
It works on older Mobilphones(V.1.2) like Nokia 3650.
Now I tried to use it on the Nokia 6630 and I get a KErrNotsupported error (-5).
Which device and sdk do you use (the same?).
If you have a look at the examplecodes in the SDK2.1FeaturePack 2 you find all examples of older SDKs exept the HCI-example-code (?!?!?). Perhaps in newer SDKs its not supported. If you have solved the problem please write how.

In Nokia 6630 you have to use Publish&Subscribe API for getting BD_ADDR or change the discoverability mode, e.g.

See Bluetooth changes -related readme.txt document in the installation package for further details.

Thanks for your reply.
I've read the release notes of the Feature Pack 2 now, but where are too few informations about the Publish&Subscibe API. Where can I find this api or documents about it. I haven't found anything about this in the SDK-Help.

Another Question:

I'm developing in C++.
Is the Publish&Subscribe API for Java only or also for C++

[Sonny78]

Oh, I've found it. Thanks for your help.

Could you, please, say where have you found the information about Public&Subscribe API?

[Sonny78]

You can find informations about the Public&Subscribe -Api under

http://www.forum.nokia.com/html_read...,,6020,00.html

or just search for "RProperty Symbian C++" in google.

It works. But where is no paper or document about how to use Publish&Subscribe-Api with Bluetooth.
Just search for the header file bt_subscribe in your sdk:
.../8.0.a/S60_2nd_FP2/Epoc32/include/bt_subscribe.h

Here you can find all keys and properties you need.
For example to get the BT device address:

TPckgBuf<TBTDevAddr> aDevAddrPckg;
RProperty::Get(KPropertyUidBluetoothCategory, KPropertyKeyBluetoothLocalDeviceAddress, devAddrPkg);

To write a Property, like the Discoverbility:
RProperty::Define(KPropertyUidBluetoothControlCategory, KPropertyKeyBluetoothLimitedDiscoverable, RProperty::EByteArray);
TPckgBuf <TUint32> type = aIACType;
RProperty::Set(KPropertyUidBluetoothControlCategory, KPropertyKeyBluetoothLimitedDiscoverable, type);

Shouldn’t the property defined using the KPropertyKeyBluetoothLimitedDiscoverable key be of integer type and take a value from the enum THCIScanEnable? Anyway, I tried this to make my device indiscoverable but to no avail. Has anyone succeeded in preventing a 8.0a device or higher from responding to inquiries?
