[Bluez-users] Packet type

[-- Attachment #1.1: Type: text/plain, Size: 711 bytes --]

Hi,

 I wrote a program to create a bluetooth connection using hci_create_connection  and the devices get connected but how do I send and recieve packets using this connections. My aim is to test the communication link between the devices using different packet types(DM1,DM3,DM5...)

Can someone please give me a hint on how this can be done. I have been struggling a lot as I am new to Bluez and C programming.

thanks

Marco.

don't do that. Use a L2CAP socket.

Hi Marcel,

Thanks for the reply, but if I use a L2cap connection I cannot specify whether I want to use HCI_DM1 or HCI_DM3 packets in my program ??

final goal is to test each packet type using any connection ??


regards,

Marco.

and what do you expect as result out of it. First of all HCI_DM1 is
always available and second let the link manager do its jobs and allows
it to use all available packets.

Hi Marcel,

 Final aim is to provide an estimate of the expected frame error rate (FER) per channel of a series of Bluetooth links using six different types of packets (DM1, DM3, DM5, DH1, DH3, DH5).

thanks,

Marco.
