cyw54907 is only high speed wifi with mcu,I wang to use cyw54907 in  product device .Do cyw54907  Mass production?

using wpa_supplicant.conf I set freq_list but in roaming scenario driver still connecting to DFS channels

Meanwhile, is CYW43455 supported in wicked sdk 6.4? I downloaded non-MFi version wiced sdk 6.4 and there's no support under cyw43455.

We have a new Cypress based project which has a requirement of using both A2DP Source & Sink Profile. We were able to successfully verify the A2DP Source Profile.
When we enabled A2DP Sink in the Android stack, we started facing issues of the Target Board acting as a master. The Target Board was unable to keep the pairing state with the Bluetooth Headset it was trying to pair with.
Could you please let us know if the CY 43455/43438 has the capacity to act as Master to another Sink device when A2DP sink is enabled in the Target board ?

Thank you

I am running the CYW43907 in sleep mode (not deep sleep).

How can i use a GPIO pin ( WICED_GPIO_6) as a wake source? I have the pin externally pulled high with a 47K resistor and attempting to pull low through a button but no luck.

wiced_gpio_init(WICED_GPIO_6, INPUT_HIGH_IMPEDANCE );     wiced_gpio_input_irq_enable(WICED_GPIO_6, IRQ_TRIGGER_FALLING_EDGE, gpio_callback, NULL); /* Setup interrupt */

Does not work in sleep mode, it works well in normal mode.

If i add

wiced_gpio_deepsleep_wakeup_enable( WICED_GPIO_6, IRQ_TRIGGER_FALLING_EDGE );

It still does not appear to wake up, but this also does not provide any callback mechanism to unblock a task if needed.

WICED SDK 6.2.1

We have been testing HFP/HSP for a new Project and we have come across an issue where the Audio packets are not routed to the Bluetooth Headset. We try to establish a Skype Call and we are not able to hear any Incoming Audio in the Bluetooth Headset. It is clear that the ACL data packets move through UART and the SCO packets for Voice communication move through PCM.

We would like to know which are the PCM cards that are necessary to be interfaced  to CY 43455 & CY 43438 to make audio communication possible.

Thank You.

Hi forum,

as I found in the documentation and in some other threads in this forum: OTA2 will not run on STMF4 devices because of insufficient RAM.

It says that OTA2 itself consumes 304k of RAM. Our version of the STM MCU has only 320k in total and ~100k will be used by our application.

So just for clarification some short questions:

• Is the above still valid?
• Can someone shed some light on why OTA2 code is consuming so much RAM? (Just to better understand the requirements and where they come from)
• What if we add external SRAM to the system? Can OTA2 make use of it?
• Can one strip-down the OTA2 functionality to consume less RAM? (e.g. we do not need the SoftAP push feature)
• I also read somewhere that only the 43907 module supports OTA2, all others support only OTA framework SW. Is this true? We use a 43438 module, does that imply that OTA2 will not work even if we meet the RAM size requirements on MCU side?
• If the above bullit is true: What has the module to do with OTA2? My understanding so far is that the MCU loads the FW to the module via the dedicated interface (in our case SDIO). How does this affect the OTA2 software?

If someone can help to clarify the points above, that would be of great help. We are in the phase to decide whether OTA2 is an option for us or if we have to implement our own SW for that purpose. OTA seems to be less attractive featurewise, even though it is stated as a possible solution for this HW combination.

Thanks for your support

I'm working on an application where i don't need deep sleep of application core. So, i don't need tiny bootloader. How can to disable this so that i can use this memory for other purpose?

in quick start guide bcm943341 is has the J7 mapping right in section 3: hardware details for that board,

I need the same thing for BCM94343, which has no quick start guide with the J7 mapping.

With the 943341 J7 has 28 pins

with 94343 it has 30 pins,  where is this mapping outlined between bcm94343 and the dev board???

any one know.

Sincerely,

Gillian.
