Wi-Fi Combo Forum Discussions

I am interested in the question of whether it is theoretically possible to use the bcm43438 chip on other frequencies than 2.4G and 5G, which is presumably equivalent to the question of whether the band filtering is done in hardware inside the chip, in software inside the chip or in hardware outside of it.  I am fully aware of (and have no intention of ignoring) the separate regulatory issues, and equally so that the firmware would not support this.  It might be helpful to state what is probably obvious: that I know more about hardware programming than about hardware assembly.

Thank you!

Could some one share Package reliability and Qualification reports for part # CYW4356XKUBGT? Please help.

Working with WICED-Studio-5.2, Win7, BCM94343WWCD1_EVB Evaluation

WICED Evaluation boards have a FTDI FT2232 chip which provides debug capability with USB to UART+JTAG.Sample source　can download to the Board　and run,add the build target to ‘snip.uart-BCM94343WWCD1-debug download’, but debugging of the snip.uart sample app on the BCM94343WWCD1_EVB   always fails.

when Debugging failed　even if you push F8,It will not respond to anything,Stop debugging and it will move properly。

screenshot As shown below

Sometimes　when Debugging success　、As shown below

How can solve the problem?

We are using BCM4343W as BLE Module and we are trying to scan for other BLE modules through our application. We found that the configuration of scan is available as a parameter of wiced_bt_stack_init() API. We have a requirement to dynamically change scan configuration from Passive to Active scan without re-initializing the WICED BLE stack.

Is there any alternate way or API's for setting the scan parameter in WICED without re-initializing the WICED BLE stack?

WICED stack used

Version = 4.1.1

Will the CYW43353 be supported on WICED in the near future?

It will be very useful to use this chip with, for example, a cortex M7 microcontroller for high bandwidth / low power consumption application.

I hope someone could shed some light!

Thanks,

Abel.

Dear Cypress,

CYW43909 Programmer’s Guide was mentioned in http://www.cypress.com/file/298231/download   with document number: 002-15381

Please, provide the access to this file.

Thank you.

Hello,

I want to manage the memory of my microcontroller STM32F415 (192k bytes SRAM including 64k bytes of CCM data RAM) with two features:

AMQP (~ 30k bytes required)

and

Bluetooth communication (~ 25k bytes required)

However after a test it is published that I do not have SRAM available in the microcontroller.

At the beginning of : void application_start (void), the available SRAM is close to 32k bytes.

So I have three questions:

1) "192k bytes SRAM including 64k bytes of CCM data RAM" does it mean the maximum SRAM available memory is 64k bytes or 192k ?

2) Can I reduce the SRAM required for AMQP or Bluetooth communication? And how if it's possible?

Or

3) Can I reduce SRAM used before the start of my project? And how if it's possible?

(The project uses RTOS: ThreadX and Network stack: NetXduo).
