Studio Bluetooth Forum Discussions

I am currently working with a CYW20735B0 chip. The newest WICED Studio 6.4 seems to only contain platform files for 20735B1. Do I need to use an older version of WICED Studio? If so, where can I get it?

Thank you!

Consider the scenario- Two CYBT-413034-02 nodes are present (namely node A and node B). Also one BT speaker is present.

I am using BLE mode. Node B is the advertiser. Node A is the scanner and it initiates connection to node B and gets successfully connected. Can node B be connected to BT speaker also parallelly and send some sounds over BT, If yes,then my doubt is whether same program in node B, handle both

(a) BLE connection to node A,

(b) and audio transfer to BT speaker.

Also my question is to where to store specific sound related data in node B.

It would be advantageous to me, if the connection between node B and BT speaker is also in BLE mode (and audio data transfers also in BLE mode). My requirement is low power.

Is there any readback etc. code duplication protections for CYW20719 or any of the other BT chips?

Thanks

Is there any sample project for BLE serial port on CYW20706 platform?

I found this post: BCM4343W: BLE to UART bridge (ie. emulation of Serial Port Profile)? . But it's not enough to create a full application.

Please help to provide sample project or detail sample code.

Thanks!

Hello,

I would like to ask the following additional Community questions: [WICED-based EZ-BT Module] Certification of EN 62368-1

* I would like to use CYBT-343026-01.

CYBT-343026-01 is currently certified with "EN 60950-1", but not with "EN 62368-1".

"EN 60950-1" will expire on December 20, 2020.

Question 1.

Can CYBT-343026-01 be sold in the EU without "EN 62368-1" certification after December 20, 2020?

Or can CYBT-343026-01 continue to use "EN 60950-1" certification after December 20, 2020?

* For Bluetooth modules that are already "EN60950-1" certified, I would like to confirm that there is no need to update to EN 62368-1 after December 20, 2020.

Best regards,

Kenji

Hi

Could you provide the information or datasheet about UART  for us?

I want to know about the output information of TXD and RTs of UART.

Is it CMOS or OpenDrain?

And whether external pullup is required?

Thanks

Hi,

I am using the CYBT-343026-EVAL board.

I would like to test it as A2DP source (audio route is I2S).

Could anybody let me know whether it is possible to transfer data on the assumption as follows?

desired behavior is:

• I2S configuration is slave mode, 88.2kHz or 96kHz sampling, 24bit, stereo
• Down sampling in BT module
• transfer data via A2DP (SBC 48kHz sampling, 16bit, stereo format)

Has Wiced SDK Down sampling functionality for I2S data?

or I must set I2S configuration exactly the same as SBC format?

Thanks,

Kazushi

Hi

Is there a low power mode that it does not restart?

I want to know another low power mode software api besides wiced_power_save_start();

Thanks.

Hi,

I built the "serial gatt service" like this "demo.hci_serial_gatt_service-CYBT_343026_EVAL download DIRECT_LOAD=1 build"

Then download to the CYBT343026 board using "Wiced client control".

It has shown "Launch RAM". However, it still advertises as the previous demo "hello". This new demo application is not working.

Does it need extra downloading?

Thanks
