[bluetooth-dev] AW: CSR Bluetooth hardware

Hi Craig,

the synching sequence of the Casira is thrown out again and again, but this
is not this sequence. The synching sequence contains the byte sequence 0xDA,
0xDC, 0xED, 0xED. Also there has to be an 0xC0 delimiter at the beginning
and at the end. Be sure that parity is enabled at your host PC.

Before you are going to flash a new firmware to your Casira, be sure you
have the BC01b Chip, since BC01a will be destroyed with firmware newer than
beta-7.  With the PSTOOLS you can disable BCSP, Parity and Synching and
enable H4. After that there should be no problem.

best regards

Betreff: CSR Bluetooth hardware

I have recently started to work on CSR Bluetooth hardware using the Casira
Bluetooth DevKit.

I hook up on the BT Casira devices to my RS-232 port, set the port rate
to 115200bps, and observe the following characters being transmitted
from the Casira:

0xC0 0x01 0x90 0x8f 0xaf 0x57 0x60

This sequence is repeated over and over.  Doesn't look like a HCI-UART
packet sequence to me.  (Must be their BCSP protocol format?)

Question: How do I switch over the Casira module to speak HCI-UART
so that I can use the AXIS stack?

Thanks for any help you can give me,
Craig Gwydir
