I use BCM20736 in my device.
IT is connected to external MCU by SPI.
Help to understand - how to control the bcm20736 via the SPI.
Can i use bcm20736 without programming?

On the SiP module, you can use Spiffy2/SPI2 to connect to your external MCU. Spiffy1/SPI1 cannot be used as it shares pins with the I2C interface that is used to connect to the internal 512K of EEPROM. The device come preloaded with a stack, profiles and device drivers loaded into ROM, but you will need to load an application of some type to use it within your specified application. The WICED™ Smart Hardware Interfaces document is a good place to start as it provides some sample code you may be able to use.

How bluetooth module started?
I must send something to BCM through SPI (command) or It running yourself with the default settings and can be found by remote device (example:mobile phone)?

You write an application and load it over the HCI_UART in programming mode.
Reset.
The module then sees that a valid program exists when it boots and comes up in application mode with the program running.

"You write an application and load it over the HCI_UART in programming mode."
If i didn't have connect MCU to BCM over the HCI_UART, only SPI? How should the programming module?

The first time you program the module, it must occur over the HCI UART.
After this initial programming occurs, you can then use the Peripheral UART or Over The Air (OTA) for firmware uploads. There are examples of each provided with the SDK under the /apps directory.
