I have two questions for you : 1) How do I send ACL data between two devices using HCI socket ? 2) I tried sending a stream of bits using SCO connection. The program is similar to scotest. Eventhough, sending and receiving works but the data received looks completely corrupted and different from data sent. received data is like eg : *******� hcidump: > SCO data: handle 44 dlen 48 > SCO data: handle 44 dlen 48 > SCO data: handle 44 dlen 48 > SCO data: handle 44 dlen 48 > SCO data: handle 44 dlen 48 > SCO data: handle 44 dlen 48 > SCO data: handle 44 dlen 48 > SCO data: handle 44 dlen 48 > SCO data: handle 44 dlen 48 > SCO data: handle 44 dlen 48 > SCO data: handle 44 dlen 48 > SCO data: handle 44 dlen 48 > SCO data: handle 44 dlen 48 > SCO data: handle 44 dlen 48 > HCI Event: Disconn Complete (0x05) plen 4 Is there some data conversions to be done before sending or receiving data?

Thanks for the reply. I have two questions for you :

1) How do I send ACL data between two devices using HCI socket ?

2) I tried sending a stream of bits using SCO connection. The program is similar to scotest. Eventhough, sending and receiving works but the data received looks completely corrupted and different from data sent.

received data is like
eg : *******�

hcidump:
> SCO data: handle 44 dlen 48
> SCO data: handle 44 dlen 48
> SCO data: handle 44 dlen 48
> SCO data: handle 44 dlen 48
> SCO data: handle 44 dlen 48
> SCO data: handle 44 dlen 48
> SCO data: handle 44 dlen 48
> SCO data: handle 44 dlen 48
> SCO data: handle 44 dlen 48
> SCO data: handle 44 dlen 48
> SCO data: handle 44 dlen 48
> SCO data: handle 44 dlen 48
> SCO data: handle 44 dlen 48
> SCO data: handle 44 dlen 48
> HCI Event: Disconn Complete (0x05) plen 4

Is there some data conversions to be done before sending or receiving data?

Note: I know that the best way to transfer data between devices is using l2cap but these question are part of my experiment to test different connections. So,please bear with me.

best regards,

robert.

the HCI socket is not working this way. Use L2CAP if you wanna receive
incoming connections and data.
