bluetooth stack cc2564

Hi Hong,

It should be possible given that the CC2564 is a BT HCI device. You will need to do couple of tweaks in the HCI driver to support the CC2564 though.

Miguel

hi Miguel

thanks  for your reply.

can Bluedroid stack be used with cc2564?

what software package do i need have to control cc2564 device running android?

thanks!

Hi,

Yes it should be possible.

See below for bring up Bluedroid on Android, we have a detailed step explained in the below link for WIlink devices, But the same can be used for CC2564 devices as well, But as Miguel mentioned you will need to do couple of tweaks. http://e2e.ti.com/support/low_power_rf/f/538/t/294284.aspx

Hi,

thanks  for your reply.

Bluez stack can use with cc2564?

regards.

Yes

Hi,

thanks for your reply

how to port Bluez to android4.3?

regards!

Hi,

you can follow the instructions mentioned in the post http://e2e.ti.com/support/wireless_connectivity/f/307/p/266760/937992.aspx#937992 

As android 4.3 comes with Bluedroid, If you want to use on it, i don't think it is a straight forward job. In addition to the above, you need to get the BlueZ library which can be ported on android and then start. I am sure you will find more information on the net.

Hi,

thanks for your reply.

i did follow by the guideline and meet below error:

E/uim-sysfs( 2786): uim: Inside main
E/uim-sysfs( 2786): uim:BT/FM/GPS would be unavailable on system

Can you help me solve that?

thanks!

Hi,

It looks like your kernel build does not included Shared Transport (ST)

Hi,

thanks for your reply

I did build ST in kernel but now it error:(stk) :download firmware failed

Hi,

Looks like GPIO is not toggled properly.

This should be high before there is any communication with the chip.

Could you please check if the connection with the chip is fine when you face this issue. Also if possible please check if the voltage on GPIO is driven high.

you can also probe the UART lines to make sure that the UART configuration is correct.

Also check if you have done the software configuration correctly in the board file with respect to the UART you are using.

Hi, 

thanks for your reply.

i has modify path of .bts file and config UART correct, but now it error:

Can you help me solve that?

Hi,

As mentioned in my earlier post it still looks like the problem is with the GPIO. 

Hi,

thanks for reply

i has config GPIO correct but hci_tty not open. now Bluetooth has run good.
thanks!
