TiWi-uB2 stop loading init script

Vyacheslav Lebets

Other Parts Discussed in Thread: CC2564

When debugging dowload init script, I see: after sending command packet 0x01, 0x38, 0xfe, 0x00, TiWi-uB2 stops responding to MCU, i.e. do not return to host event packet.

I use "bluetooth_init_cc2564_2.10.c". When try to load init scripts ver. 2.5, 2.8, 2.12 and same, after sending that command packet, TiWi-uB2 stops responding.

In command packet:

0x01 - type of packet

0x38, 0xfe - opcode

0x00 - parameter total length

opcode 0xfe38 where

0x3F - OFG - is reserved for vendor-specific debug commands

0x238 - OCF.

But BT core specification do not include this OCF.

May be anybody know what is this opcode means?

And why TiWi-uB2 stops responding ?

Best regards,

Vyacheslav.

Hi,

It is strange that, it stops responding near a release lock command this should not happen. It is a vendor-specific HCI command.

Can you please provide me the Service pack(init script). As what I downloaded for here http://processors.wiki.ti.com/index.php/CC256x_Downloads does not have this problem.

also let me know the below:

what is the part number(order number) TiWi-uB2.

what is the result of HCI Read Local Version Information?

what is the stack you are using?

I try to load init scripts, downloaded from http://processors.wiki.ti.com/index.php/CC256x_Downloads for cc2564.

Also I try to load script, recomended by LSR from http://www.lsr.com/ProductsWiki/tabid/163/topic/TiWi-uB2/Default.aspx (named "Bluetooth patch files").

All scripts stop loading on that command.

I use TiWi-uB2 EM board 450-0105 Rev 3. part num: 10D0B0165

Hi,

Thanks for the detailed information.

You should be using "480-0025 - FCC/IC/ETSI BT 2.1 + EDR, FCC/IC BT 4.0 all certified antennas" service pack from http://www.lsr.com/ProductsWiki/tabid/163/topic/TiWi-uB2/Default.aspx, as recommended by LSR.

If your host processer is MSP430BT5438 could you please try the hardware evaluation tool in Transparent Mode and download the service pack and see if it works?

Also I would like to know how are you downloading the service pack?
