Wireless Connectivity Forum Discussions

I was wondering which products in your company support the TBFC(Triggered Broadcom [Bluetooth] Fast Connect) function?

Could you please provide the relevant product models under production, as well as the access to these chip evaluation boards or download links?

I need the relevant IDE,SDK and hardware to develop these functions;

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.

Log contnets:

Hi,

We bought CYBLE-013025-EVAL evaluation board.

Now trying to integration the CYBLE-013025  module into our board but due to a lack of documentation we are struggling to talk to it via UART. It is not clear which UART or PUART should be used as it was working on the EVAL board when talking via a terminal.

Could you please point me out where I can find the schematic diagram for CYBLE-013025-EVAL board?

Hello 

I want to use the CYW920721M2EPA2 as a bluetooth audio sink from bluetooth to I2S but without the arduino hat from the CYW920721M2EVK-02. 
It semes like that the example "Audio Sink" in modustoolbox requires an external codec sc47L35 which I figure is on the arduino hat. The terminal just repeatedly writes:
"
DRIVER_CODEC R16 1800:0000
Codec cs47L35 not detected
"

Is it possible to use an internal codec? or is there another method of generating I2S from bluetooth with the CYW920721M2EPA2 bluetooth module?
Thank you for your time!

Dear Infineon team,

we are experiencing the following behaviors.

HW: CYW4343W (Laird Sterling LWB) within Variscite DART-6UL SoM

FW: BCM43430A1_v001.002.009.0142.0511.hcd (within Yocto Dunfull, kernel 5.4.142, bluez 5.55)

Repro Steps:

- bluetoothctl: power on

- bluetoothctl: advertise on

Connect using BLE Scanner App on phone.

- bluetoothctl: disconnect

Phone with Android 11 & 12 force an automatic reconnection.

- bluetoothctl: disconnect

Phone with Android 11 & 12 force an automatic reconnection but the kernel now notifies the following messages

[17196.416963] Bluetooth: hci0: command 0x2006 tx timeout

[17198.497135] Bluetooth: hci0: command 0x200a tx timeout

The only way to recover is stopping the hci interface and the brcm_patchram_plus binary to reload the BT firmware and restart the BT interface.

Phones with Android 11 and 12 show this behavior. Tested phones: Samsung Galaxy S20/S22, Google Pixel 3XL/4A/6 and Nokia 5.3

Phones with Android 10 or below do not show this behavior and upon disconnect, the phones don't try reconnecting.

Are you aware of any known similar behavior ?

Thanks

Best Regards

Hi~

I tried to use Modustool 3.0 because I received email for the Newly released Modustool.

But I cannot change BSP model from based chip model(CYW20706) to same based module(CYBT-343026-01).

But I cannot find that module in Library manager.

Is it a new policy? or some bugs?

Thanks alot
