for a CYBT-353027-02 device, is it possible to obtain the BT MAC address from BT transport layer?
I've searched the BT transport layer API but cannot see anything that return the MAC address.
It looks like BT-SDK 3.3 is available on GitHub.
At least, there is a tag 3.3 on:
Are there any release notes available like it was for 3.2:
I have a question about how to save firmware from CYW20706 to file.
We can use ModusToolBox, Chiploader and ClientControl download FW into CYW20706,
and is it possible to save FW from CYW20706 to file?
I have an issue such that when I play audio via A2DP or have an open SCO connection the HCI UART interface stops working.
When I stop the audio stream the HCI interface resumes operation.
we just received CYBT-213043-EVAL to evaluate the CYW20819 chipset.
I'm using the board with external BT stack (https://bluekitchen-gmbh.com/) and external MCU host and everything seems to work fine (I pull CTS high when power/reset the EVB, in order to let the chipset enter in HCI mode).
I'm also enabling SCO_Routing to transport level (using command Write_SCO_PCM_Int_Param -> [0E 04 ]: 01 1C FC 00
Something is not working as expected: SCO audio channel is established correctly, but SCO data start to be received after about 4seconds, and they are received not as SCO packet but as vendor specific events.

After 8seconds, I'm not receiving anything else.
1) where can I download HCI vendor specific command list for CYW20819?
2) why the CYW20819 stops to route SCO packets over HCI after about 8seconds?
Thank you for the support.
Hello Infineon Support team.
We would like to evaluate I2C master using CYW920721B2EVK-02.
In the first place, there are No I2C reference sample code for "KitName:CYW920721M2EVK-02" in ModusToolBox version 2.4.0.
So, instead of it, we referred following.
- Kit Name: CYW920721M2EVK-03
- Template App: HAL I2C Master
However, no I2C signals are observed at SCL(J3:1),SDA(J3:2) on the board.
Please give me advice to observe I2C signals using CYW920721B2EVK-02.
The CYW920719Q40EVB-01 User Guide says to install Wiced Studio, and that the 20719 demos can be found in 20719_B1_Bluetooth folder within Wiced Studio's installation folder. I installed Wiced 6.6 but I have only a 43xxx_Wi-Fi subfolder. How do I get the 20719 demo projects? (I realize Modus Toolbox has 20719 support, but it doesn't contain any BLE-Midi demos, which are what I am interested in). Thanks, Norm.
Hi, we are building an UART to Bluetooth product with cybt-343026-01 module, and when too many data is sent on Bluetooth side and UART baud rate is too low (ie. 9600), it's losing data even with UART hardware flow control enabled.
I suspect it's because UART CTS is not implemented in EZ-serial firmware of this module, is there any way to fix this? or send me the EZ-serial source code (can be under NDA) that I can fix?
This bug is listed as item c. of limitations in this doc:
When I checked the data sheet of CYBLE-014008-00, I could not confirm the MIC mark.
Is the MIC mark displayed on the actual Module?
My perception is that the MIC mark must be displayed on the Module board or shield.
Is this recognition correct?
For example, if the MIC mark cannot be displayed on the Module, is it acceptable if the MIC mark is included in the data sheet (instruction manual)?
I also believe that displaying this mark on the customer's end product is voluntary and not obligatory.
Is this recognition correct?
Let me confirm the meaning of this sentence on the data sheet.
"End product can display the certification label of the embedded module."
I am curious about what is the correct max Tx Power for CYW20706,
from specification it said +12dbm
, but according to URL, it said max Tx Power is +8dbm https://community.infineon.com/t5/Resource-Library/Configuring-Transmit-Tx-power-on-the-CYW20706/ta-p/246345
if I configure .max_pwr_db_val = 9 and wiced_bt_ble_set_adv_tx_power multiple of 4 from +8 dBm to -16 dBm, it seems work.
The below picture is my roughly test.
Is it possible to configure tx power to +12dbm?
And how to configure .max_pwr_db_val ?Show Less
