AIROC™ Bluetooth

 Hi~

I received PIN Code feature was  not supported with latest spec before.

But our customer asked the relevant documentation for persuading an end customer.

Is there any documentation for above?

Many Thanks

Hi,

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.

BR,

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 need to use cybt-343026-01 as a regular bluetooth module on arm board.

Currently we upload empty Modus Toolbox project using patchram utility via HCI UART.

But scanning does not work. Neither 'hcitool scan' nor 'hcitool lescan' returns non-empty result.

Is there specific code should be added in project?

I purchased CYBT-343026-EVAL and am trying to check the connection by sending Classic commands through TeraTerm.

However, the connection fails.

The address is correct for the connection.
The connection is to CYBT-343026-01.

Please let me know if you know how to solve this problem.

The connection is unstable, sometimes it is possible to connect.

The program in CYBT-343026-EVAL is still in the same state as shipped and no other program has been written to it.
The firmware version of CYBT-343026-EVAL is 1.2.29.

Hi,

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.

e.g. 

[00:00:24.408] EVT <= FF F4 1B 03 01 ED FF 13 00 00 00 ED 00 E0 41 C2 0F 41 04 ED 00 E0 02 00 41 00 08 ED 00 E0 00 00 00 00 0C ED 00 E0 00 00 05 FA 10 ED 00 E0 00 00 00 00 14 ED 00 E0 00 02 00 00 18 ED 00 E0 00 00 00 00 24 ED 00 E0 00 00 07 00 28 ED 00 E0 00 00 00 00 2C ED 00 E0 00 00 00 00 30 ED 00 E0 00 00 00 00 34 ED 00 E0 34 ED 00 E0 38 ED 00 E0 38 ED 00 E0 3C ED 00 E0 00 00 00 00 00 E1 00 E0 0F FC 4F 00 04 E1 00 E0 00 00 00 04 00 E2 00 E0 01 7C 64 00 04 E2 00 E0 00 00 00 00 C0 00 32 00 24 00 08 00 78 13 30 02 72 D6 2C EA DC A4 4E 0C 7E 89 B0 44 CF 01 CD 68 C3 32 59 80 8E 0F 01 BB 3C CA 6D 4A 15 0A 06 A0 80 08 04 DD 33 9B C1 2E 08 92 29 74 93 E1 DA A7 36 21 4C 05 0E 91 04 EF 41 BF 5E 90 44 53 08 15 15 D2 05 C1 75 4D F1 E4 6B B2 1F 3C 1C 34 09 C1

After 8seconds, I'm not receiving anything else.

Questions:

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.

Best regards,

Alessandro Morniroli
