Hi Sir,
please provide PItool for calibration.
thanks.

HI ,
Does 4373 support signaling testing ?

Hi Sir,
please provide 4373 BT BTP file for testing
thanks.

We're looking to prototype the new standards being developed in ETSI ISG NIN https://www.etsi.org/technologies/non-ip-networking over wireless PHY, and would like to do this on Raspberry Pi which we understand includes the CYW43438. There's detail of the technology, which has already been implemented over wired links (gigabit Ethernet PHY), at http://www.ninetiles.com/Flexilink_details.html
The packet format is different from TCP/IP and we also want to be able to set up schedules for ultra-low-latency flows.
We think this would require modification of the CYW43438 firmware; is there a way we could get access to the necessary documentation, libraries, etc, please?
We have plan to use the BW2455-44P (sdio/dhd-android-1.363.125.19 <driver> ) with Sigma Star SDK(SAV837SDK_V15/Linux(kernel) version : 4.9.227).
The command(ping) is worked fine after connecting to AP.
Howerver, When I tried to do live view stream with VLC on the PC after the unit connected to AP(Router, The PC and unit are in the same nework), There was Cmd error ( [sdmmc_1] Err: #Cmd_53 (0xA900004A)=>(E: 0x0100)(S: 0x00000000)__(L:1059)(B:74/74)(I:0/1) dhd_bcmsdh_send_buf: sdio error -1, abort command and terminate frame).
- So, Could you help me how to fix the issue as soon as possible ?
- Please let me know which driver I should use to fix the problem.

Show LessHi,
We made a custom board based on the CYW43907 dev kit design using 1GC modules. On one of our prototypes there is a ~80usec high glitch on GPIO_12 which happens right after Hib wake is toggled.
The glitch happens almost instantaneously after the hib_wake toggle, and a few hundreds of millisecond before the firmware is actually running.
I am not able to reproduce this on other boards, though they have the same firmware and same hardware.
The pin is clearly driven high during those ~80usec, and then high impedance (we have a 100K pull down on the line)
I am not able to reproduce this on other boards, though they have the same firmware and same hardware.
When the device powers up without HIB_WAKE, I don't see the glitch.
What could cause such a glitch?

Hi
I use Cypress 4343 - my component is Laired sterling..
I see problem with scan results,
In my environment the RSSI value that print in the log is "OFF".
I check inside the code and I found that this "OFF" arrived from WICED_SCAN_RESULT_FLAG_RSSI_OFF_CHANNEL
but I don't understand what the problem? who set the flags to be WICED_SCAN_RESULT_FLAG_RSSI_OFF_CHANNEL
Can you help me

Show LessWe have developed original board by using STM32H743 and CYW4343W.
In the whd_bus_sdio_protocol.c, we got error this kind of error. So how do we solve this problem.
Note: We are using the "STM32 Connectivity Expansion Pack1.1.0( https://github.com/Infineon/stm32-connectivity )
