Hi ..

is it possible to open a simultaneous SPP and BLE connection with the BCM20706S ??

BR Michael

hi.

i use 20736S custom board and just met a problem.

please tell me something wrong or missed.

after boot, my code enter deep sleep by button event or timeout.

button event wakeup is ok.

after then, i hope to enter deep sleep again.

at this time, button event is success, but next log message show repeatedly.

...

next is my code

ds_create()

{

...

bleprofile_regAppEvtHandler(BLECM_APP_EVT_ENTERING_HIDOFF, (BLECM_NO_PARAM_FUNC)app_enter_hidoff);

bleprofile_regAppEvtHandler(BLECM_APP_EVT_ABORTING_HIDOFF, (BLECM_NO_PARAM_FUNC)app_abort_hidoff);

...

devlpm_init();

devlpm_enableWakeFrom(DEV_LPM_WAKE_SOURCE_GPIO);

interrupt_handler_mask[GPIO_PUSH_BTN / 16] |= (1 << (GPIO_PUSH_BTN % 16));

gpio_registerForInterrupt(interrupt_handler_mask, gpio_intr_handler, NULL);

gpio_configurePin(GPIO_PUSH_BTN / 16, GPIO_PUSH_BTN % 16, GPIO_EN_INT_RISING_EDGE, GPIO_PIN_OUTPUT_HIGH);

...

}

app_enter_hidoff() {}

app_abort_hidoff() {}

ds_timeout()

{

bleapputils_delayUs(500);

bleprofile_Discoverable(NO_DISCOVERABLE, NULL);

bleprofile_PrepareHidOff();

}

Why 1st time ok, but every 2nd time make infinite loop?

thanks.

I want to know if the SDK has a OS, like free RTOS or  UCOS or other?

And I want to create two or three custom threads, what should I do?

Thanks.

Could you send me the datasheet of the antenna?

I also want to know how can I do to test its RF performance, as Certification Lab need to test our modem but can't find a RF switch.

We are testing out the SPI2 slave communications of the BCM20736E with the following pin configuration:

SPI_2_CS: P32

SPI_2_CLK: P24

SPI_2_MISO: P25

SPI_2_MOSI: P27

Prior to our code being loaded and executed, the ROM code is driving the output of the chip select line.

We monitored the chip select line, and there is UART ascii data being put out on that pin prior to our reconfiguration for SPI.

See Terminal_Broadcom.jpg

Because it takes the Broadcom module three seconds to load, the master device is already up and running by the time the module is configured.

This is causing a collision when the master device attempts to communicate to the slave when it's driving the port with UART data.

Both devices end up driving the line at the same time.

How do I stop the Broadcom UART debug output on that GPIO port?

I see the following while trying to build the hello_sensor on MAC using the 2.1.1 IDE.

as i know, the return value 0x08 of emconinfo_getDiscReason() is connection timeout (link loss).

is that BLE spec ?

I wonder other disconnect reason value.

in my android phone log, below disconnect reason is reported..

help me...
