HCI send and receive
Hi Marcel,
I want to set up an HCI connection between 2 dongles, see the default packet type at connection, then send data. Now keeping the existing connection, I want to change packet type and then send data....Is this possible????
Should I write small programs just to send and receive data with known payload....then I can establish a connection using hcitool and use these programs to send and receive data passing the connection handle as the parameter. Is this right??
Regards,
Manjunath

I don't see what you expect from this, but it is possible.

All API commands you need are there and you can always use the HCI raw socket. It is a H:4 based, one command or data packet per read/write interface. And it is a good idea to send L2CAP conform ACL data packets.

I don't see what you expect from this, but it is possible.
What i am expecting is a measure of varying throughput with change in packet type.

I am ignorant about this.....are you saying HCI raw socket provides the one command or data packet per read/write interface....can you elaborate...
And it is a good idea to send L2CAP conform ACL data packets. Does this mean it would be a L2CAP connection as you send some chips expect L2CAp frames???

I don't see for what this will be good, but you can simply set the same packet type on both sides with hciconfig and then use l2test or rctest for measuring. Or create a PAN and use standard IP tools.

It is as I said. You can write/read H:4 on a HCI raw socket.

I think some chips do and actually also the remote Bluetooth stack might expect L2CAP.
