[Bluez-users] CSR Bluetooth firmware upgrade

[Bluez-users] CSR Bluetooth firmware upgrade

[automatic_jack]

Hi all,

my HP Ipaq h2200 has a CSR Bluetooth chipset and I use Familiar
(GNU/Linux) v0.8.4 on it; this is the output of "hciconfig -a":

hci0:   Type: UART
        BD Address: XX:XX:XX:XX:XX:XX ACL MTU: 192:8 SCO MTU: 64:8
        UP RUNNING PSCAN ISCAN AUTH ENCRYPT 
        RX bytes:569 acl:0 sco:0 events:29 errors:0
        TX bytes:1334 acl:0 sco:0 commands:28 errors:0
        Features: 0xff 0xff 0x0f 0x00 0x00 0x00 0x00 0x00
        Packet type: DM1 DM3 DM5 DH1 DH3 DH5 HV1 HV2 HV3 
        Link policy: RSWITCH HOLD SNIFF PARK 
        Link mode: SLAVE ACCEPT 
        Name: 'h2200'
        Class: 0x120112
        Service Classes: Networking
        Device Class: Computer, Handheld
        HCI Ver: 1.1 (0x1) HCI Rev: 0x20d LMP Ver: 1.1 (0x1) LMP
Subver: 0x20d Manufacturer: Cambridge Silicon Radio (10)

and this one is the output of "hciconfig hci0 revision":

hci0:   Type: UART
        BD Address: XX:XX:XX:XX:XX:XX ACL MTU: 192:8 SCO MTU: 64:8
        HCI 16.4
        Chip version: BlueCore02-External
        Max key size: 56 bit
        SCO mapping:  HCI

It is possible to upgrade the CSR Bluetooth firmware to get 128-bit
encryption?

Thanks :)

in general it is possible, but you need an official firmware from HP and
a firmware upgrade utility that can be used over UART.

depends on how much you like your device. You can always try to load an
unsigned firmware, but this can render the Bluetooth chip useless and
without SPI access to the chip there is no way of getting it back.

I really love my device so...I'll try to aks on h2200 port list if
someone has just tried to load an unigned firmware
