I am using CSR 4.0 USB BT dongle (dual mode), yes every time I see it.
Sometimes with different handle (73 and different attribute0x4b)
I am using trying with BT LE (smart) HoG device which has touch pad, keypad.
I was digging more into it I got an error in the hcidump before the
above dump . which is pasted below
< ACL data: handle 75 flags 0x00 dlen 11
ATT: Read By Type req (0x08)
start 0x0057, end 0xffff
type-uuid 0x2803
> HCI Event: Number of Completed Packets (0x13) plen 5
handle 75 packets 1
> ACL data: handle 75 flags 0x02 dlen 9
ATT: Error (0x01)
Error: Attribute not found (10)
Read By Type req (0x08) on handle 0x0057
is it missing any important attribute ? 'Read By Type req' waits for
time out and drops connection. I tried enabling, when attributes are
read, in the middle connection is dropped.
How bluex comes to know about it ? is it discovered or is is mandatory
as part of Spect HoG ?
Please share your input.
Many Thanks,
Prabhu Chawandi
