Wi-Fi Combo Forum Discussions

I was surprised to learn that Partner Modules that use the CYW43907 or CYW54907 are basically not available anywhere in distribution at this time.  When I go to https://www.findchips.com​, and look up the Partner Modules (https://www.cypress.com/products/wireless-mcus), I find zero inventory for the Murata LBWA1UZ1GC-958 ("1GC") and for most others.  I see the an Inventek part (qty 158) in stock, and that's it.

So, the question is:  Without any Partner Modules in distribution, how can one actually build anything?  And, if there are no sales happening, I presume Cypress is going to EOL these devices?  What a shame.

How can I buy a development board from your partners in Russia?

I tried to buy CYW9434 here, but they told me it is impossible.

It seems that the WiFi modules should have some official certification papers (due to cryptograpy, I guess).

What can you suggest?

P.S. I have not found any information regarding throughput when working with STM32 processor.

Do you have the numbers?

Hi,

In out Hardware design we are using GPIO 5 of CY43455 as OOB interrupt. But we are not sure who to configure the same in software.

We have updated wwd_bus_sdio_set_oob_interrupt() function as follows:

{

    VERIFY_RESULT( wwd_bus_write_register_value( BACKPLANE_FUNCTION, SDIO_GPIO_SELECT, (uint8_t)1, (uint32_t) 0xF ) );

    VERIFY_RESULT( wwd_bus_write_register_value( BACKPLANE_FUNCTION, SDIO_GPIO_OUTPUT, (uint8_t)1, (uint32_t) 0x05 ) );

    /* Enable GPIOx (bit x) */

    VERIFY_RESULT( wwd_bus_write_register_value( BACKPLANE_FUNCTION, SDIO_GPIO_ENABLE, (uint8_t)1, (uint32_t)0x10 ) );

    /* Set GPIOx (bit x) on Chipcommon GPIO Control register */

    VERIFY_RESULT( wwd_bus_write_register_value( BACKPLANE_FUNCTION, CHIPCOMMON_GPIO_CONTROL, (uint8_t)4, (uint32_t)0x10 ) );

}

But this does not seem to work.

What is the correct register configuration to enable GPIO 5 as OOB. Also apart from this is there any thing else required?

Good day.
Could you explain, please.

I can't find drivers for Bluetooth LE in WICED for 43455 (RTOS).

Does bluetooth 43455 works only in Linux?

And one more - can i use WICED driver from 4343W for 43455 for BLE ? Because i have my wokred device with 4343w by WICED driver.

Hi,

I am working on Murata1LD  with  Wiced Studio6.4. ?I am trying to interface NAND flash from Toshiba TH58CVG3S0HRAIG using SPI. Whenever I read via SPI, the first byte I get is always 0xFF. For example, when I read the device id, the first byte I get is 0xFF followed by 0x98 and 0xcd which are the correct manufacturer and device ids. Can you please tell me the reason behind first byte always being 0xFF.?

Thanks,
