Hello Infineon support team.

Our customer requests us AAC codec support for both A2DP/SINK and A2DP/SRC.
According to following thread, CYW20721 support AAC for A2DP/SINK. But no mention for A2DP/SRC.

https://community.infineon.com/t5/Studio-Bluetooth/Does-WICED-6-2-support-A2DP-AAC-codec-on-CYW20706-and-CYW20719/td-p/138910
https://community.infineon.com/t5/Bluetooth-SDK/The-kinds-of-bluetooth-audio-codec-of-CYW20721/td-p/245281

Please tell me which BT chip support AAC codec for both A2DP/SINK and A2DP/SRC.

Thanks,
Tayo

Hello

I would like to download the program for CYBT-353027-EVAL and I have installed the following

WICED Studio 6.6
WICED Smart SDK 2.2.3
Platform files for CYBT-353027
But it seems that the Platform files only support the old version of the project folder - 20706-A2_Bluetooth, I try to download the sample program Hello_Sensor under WICED Smart SDK and it will report an error (as shown in the picture).

Thanks

你好

我想对CYBT-353027-EVAL开发套件进行烧录，我安装了以下

• WICED Studio 6.6
• WICED Smart SDK 2.2.3
• Platform files for CYBT-353027

但貌似Platform files只支持老版本的项目文件夹 - 20706-A2_Bluetooth，我 在WICED Smart SDK 下尝试烧录示例程序Hello_Sensor就会报错(如图)。

请问有什么解决办法?

祝好

When sending data from PC via USB serial port to CYSPP CYBT-483039-EVAL, it appears to be over-running the CYBT, without CYBT ever asserting PUART_RTS low.

• CYSPP CYBT-483039-EVAL is connected to iOS app using EZ-Serial BLE CYSPP
  
• Data is being sent using the Acknowledged Characteristic  (101)
• PUART SW5 are all turned On
• After press reset switch on eval board, I see UART RTS pin Arduino J7-P6 go high on oscilloscope
  
• I set CYBT and flow control by sending following command to PUART from the PC.
  

• "STU,B=1C200,D=8,F=1,P=0,S=1\r\n"

When PC starts sending file data to PUART over USB serial, I see the data being received on the iOS side, however, some data is missing.

I expected  PUART RTS to be asserted low to prevent 3 MB of file data from over-running the CYBT, when sending data to PUART_RX ?

I do not see UART_RTS on pin Arduino J7-P6 being set low during the 3MB file transmission.

What are potential solutions to prevent data over-running when sending data to PUART RX for transmission to iOS device?

Thank you,

Hello,

I am using the CYBT-213043-mesh-2 kit and programmed the HCI_loop_back test. I open the clientcontrol and looks like BR/EDR is disabled. I tried using FIND_ME app but no luck. 

I am looking to connect the CYBT-213043 to external devices making it discoverable for other devices to connect. Also, please let me know how to enable the diagnostic mode on this board.

Thanks!

• CYBT-483056-EVAL arrived from factory with latest EZ-Serial 1.0.10 installed.
• My CYBT device has reached the limit of four (4) bonded devices. 
• I cannot bond with new devices before removing a device from the bond list. 
• This issue is easily reproduced after Bluetooth Classic RFCOMM pairing to a CYBT-483056-02 device from a Windows or Android device. 
• Multiple people, on multiple CYBT-483056-02 devices, using various pairing devices have reproduced this issue of not being able to delete bonds once a RFCOMM pairing has been made to the CYBT-483056-02 device.

# EZSerial 1.0.10 (build 21)
@E,0040,BOOT,E=01000A15,S=02072276,P=0100,H=E8,C=00,A=E6BF3B0F0C3C,T=01
@E,000E,ASC,S=03,R=01

Using smp_delete_bond (/BD, ID=7/2) does not work.  After /BD command sent, a /QB command displays count is still 4.

Am I using the '/BD' command properly?

# Query bond list displays 4 devices bonded, 3 duplicates, 1 unique
/QB

# Remove address for Android Pixel 3A 11 bond

@R,000E,/BD,0403,C=04

# Query bond list is unchanged ??
/QB
@R,000E,/QB,0000,C=04
@E,0020,B,C=00,A=C403A8CF7884,T=FF,D=01
@E,0020,B,C=00,A=C403A8CF7884,T=FF,D=01

@E,0020,B,C=00,A=58CB523B58FA,T=FF,D=01

I have tried:

• Removing a bonded device by using smp_delete_bond "/BD" and specifying a MAC address does not change bond list
• Factory reset "/RFAC" does NOT erase bonding
• Device reset does not erase bonding.  This is correct expected behavior.
• Attempt to remove a bonded device by telling Windows or Android to forget the device does not change CYBT bond list

Re-flashing is not an option for clearing a bond list for our end customers. 

Can you please recommend a working API method to remove bonded devices on CYBT-483056-02 modules?

Thank you,

-Ed

My goal is to delete bonding by reflashing.  The smp_delete_bond command is not working for anyone on my team.

What I Tried Using WICED_MOD_Programmer

I am using Windows 11.

1. I downloaded ezserial_CYBT-483056-02.hex
2. WICED_MOD_Programmer does not have an option to select CYBT-483056-02 so I selected CYBT-483039-02 instead
3. Selected UART Adapter board
4. Selected DUT #1, Configure, and selected WICED HCUI UART (COM12), 115200, CTS, then Connect button
5. Set Firmware File Path to ezserial_CYBT-483056-02.hex
6. Checked "program BD Address" and checked "Gen a random address"
7. When I press Program button it quickly failed

WICED Studio programming of a CYBT-483056-EVAL does not seem to be a supported platform?

Thanks in advance,
