Wl12xx is not getting initialized / timeout: uim error in response: opcode is 0x1001, not 0xff36

Hi,

I see from your discription taht you ware probing GPIO Pin.

From the logs it looks like GPIO is not toggled properly. Make sure you are using the correct GPIO.

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

0x1001 is the opcode for HCI_Read_Local_Version_Information which is failing.

Hi, Sundeep Mandava,
Thank for the answer, but i do not think is a GPIO problem: see the attached
file with oscilloscope tracking of some relevent signals.
Any other idea?

Nb: I've tested the modbule on a linux 3.2.0 old demo and it works: I've to drive manually the
GPIO pin , but I'm able to use the BT module...

Hi,

From the PDF you have shared, I can see that GPIO is going high and there is a TX activity and RTS is going low after that.

Make sure that you have the Service pack in “/system/etc/firmware/” folder with correct permissions. You can get the service packs form https://github.com/TI-ECS/bt-firmware.

As you are using Android 4.1.2, I think you are using blueZ.

See the below link on bringing up blueZ on android and make sure you have not missed any of it.

Hi, thanks again:
I've detected the problem in the RTS from CPU: it is always HIGH when running Android, whilst in the
Linux version is Always LOW.

The board-am33xevm.c is configured in the same way:

static struct pinmux_config uart1_wl12xx_pin_mux[] = {
    {"uart1_ctsn.uart1_ctsn", OMAP_MUX_MODE0 | AM33XX_PIN_INPUT},
    {"uart1_rtsn.uart1_rtsn", OMAP_MUX_MODE0 | AM33XX_PIN_OUTPUT},
    {"uart1_rxd.uart1_rxd",   OMAP_MUX_MODE0| AM33XX_PIN_INPUT_PULLUP},
    {"uart1_txd.uart1_txd",   OMAP_MUX_MODE0| AM33XX_PULL_ENBL},
    {NULL, 0},
};
omap_serial.c is the same in both kernel...

Any idea about the diffetent handling  of RTS?

I've manalually setted the RTS low, and  firmware seems to be downloaded:
