Hi all,
I have a problem with scotest on Linux (same with hsplay). I can send SCO
packets, I can see them
physical being sent indicated by blinking LEDs. But I cant receive any SCO
packets.
I tried with two different chipset (features and revision see below), I am
sure that
at least the Infineon works for SCO traffic (under Symbian OS).
I tried with different kernels 2.4.19, 2.4.21, 2.6.9, with SCO support
build-in.
But it's always the same:
- hcidump of the sender indicates SCO packets sent (< SCO data: handle
0x002c dlen 64)
and error messages: CSR chipset says "HCI Event: Hardware Error", Infineon
says "Data overfolw",
but both are still sending.
- hcidump on the receiver side shows no SCO packets and no Errors
- /var/log/messages looks inconspicuous (Wait for connection, Connected from
.., Receiving..).
- The last output of scotest itself is "Sending..." resp. "Receiving...",
but
no packets are shown.
- It is the "recv" in the function recv_mode in scotest.c, that blocks
forever.
- lsmod shows module "sco" Used by 1 and it shows that "bluez" is used by
"sco" and "hci_uart".
I found no SCO-HOWTO. So what I am doing is just
hcid, hciattach and "scotest -r" resp "scotest -s <remote BDADDR>"
Has anyone an idea, what is going wrong?
Thanks, Matthias
