hello, everybody,
After I creat two SCO links from two different Teminal devices to one
Gateway device, I can not transfer any ACL data between the gateway and
teminal.
the note is:
# hcitool con
Connections:
< SCO 00:00:11:22:33:44 handle 2 state 1 lm SLAVE
< SCO 00:00:55:66:77:88 handle 1 state 1 lm SLAVE
> ACL 00:00:11:22:33:44 handle 7 state 1 lm MASTER
> ACL 00:00:55:66:77:88 handle 6 state 1 lm MASTER
Software: Using bluez stacks;
hareware: using broardcom bluetooth chip or CSR bluetooth chip.
I watch the uart port of the bluetooth chip and find that some ACL data
have been sent to bluetooth chip of gateway, but no any acl data have been
received from bluetooth chip of teminal.
Is bugs of the bluetooth chips , or the bluez stacks is wrongly used? btw:
the surport of chip manufacturer is poor.

the example above is not a CSR chip. Use the CSR chip as reference and
provide output of "hciconfig hci0 revision".
>>the example above is a broardcom chip.but using CSR chip have the same
problems.
>>the csr chip revision is: HCIStack1.2v18.2, BlueCore3-ROM

With this little information it is totally unclear. However since you
mentioned UART, it might be an UART limitation.

What does this crap mean. We support all chip manufacturers and the guys
at CSR were always helpful.
