[Bluez-users] btuart_cs module freezes Zaurus SL5000D after 30 seconds

[Bluez-users] btuart_cs module freezes Zaurus SL5000D after 30 seconds

[Chris Sterling]

I am currently having an issue where I get the following error dmesg:

btuart_cs: Unknown HCI packet with type 0xc0 received.
btuart_cs: Unknown HCI packet with type 0x00 received.
btuart_cs: Unknown HCI packet with type 0x41 received.
btuart_cs: Unknown HCI packet with type 0x00 received.
btuart_cs: Unknown HCI packet with type 0xbe received.
btuart_cs: Unknown HCI packet with type 0xa9 received.
btuart_cs: Unknown HCI packet with type 0xdc received.
btuart_cs: Unknown HCI packet with type 0xed received.
btuart_cs: Unknown HCI packet with type 0xed received.
btuart_cs: Unknown HCI packet with type 0x01 received.
btuart_cs: Unknown HCI packet with type 0xff received.
btuart_cs: RLSI

After this has filled up the dmesg with these messages, the zaurus I
have freezes. I am using the theKompanyROM which has the 2.4.18 kernel.
I get the same thing on the YetAnotherROM, as well. So, I believe that
it must be the module itself and how it works with the Mavin BT CF card.

Does anyone have any ideas on how I might be able to fix this?

Thanks.

Looks like your Bluetooth module uses the CSR chip set and is in BCSP
mode. BlueZ hasn't been told this so it's trying to talk to it in H4
mode.

Tell BlueZ to use BCSP and everything should spring in to life (I think
you just pass the bcsp option into hciattach).
