Hi,
I have compiled the a2dp sink application using WICED SDK 5.0 for the evaluation board CYW92070xV3_EVAL.
The document "CYW92070xV3_EVAL-Hardware-User-Guide.pdf" mentions that WICED application can be used for CYW2070x (CYW20706 and CYW20707).
Here, we are using CYW20706 (exact package CYW20706UA1KFFB1G) for our development, I would like to know if I can straight away download the a2dp sink application to CYW20706UA1KFFB1G which was built for CYW92070xV3_EVAL board?
The CYW2070x package on the eval board has 2 uarts - HCI uart and Peripheral Uart, I used Peripheral uart for debug logs, but CYW20706UA1KFFB1G does have only 1 uart - HCI uart please suggest on how I can send my debug logs to the PC terminal.
Thank you,
Pravinkumar
Show LessHi,
Bluetooth SIG announced "Appropriate Language Mapping Tables" from BTv5.3.
https://btprodspecificationrefs.blob.core.windows.net/language-mapping/Appropriate_Language_Mapping_Table.pdf?mkt_tok=eyJpIjoiTTJKbE1EUXpNelF6TnpSbSIsInQiOiJJYnNGdDdkRXZHb3FVVUR0dmRwWGJvWU5NM0tHcnJ1b2hjZFhDVCtxOVdyenBrcEhPemxQUkpQbU5aQkU1XC9ETVM3SXJDbUZGUFIyS1ZQTDU5SjVZNytsWWlXYXNMc1ZCZTA5YXBKSFZuVnV0VnBlYzJGZk9wYU5ZanBDdjBmOGIifQ%3D%3D
Please tell us about your company's response method and compatible RoadMap.
For example, please tell us about the response method, response time, and situation, such as "Revise all specifications" and "Revise SDK etc.".

Show LessHi everyone
The customer purchased the CYW920721B2EVK-02 Evaluation Kit.
Which application should they use on Modus if they want to evaluate another application and then return it to the factory state?
If you don't provide the source code, can you tell us how to get back to the initial state?
Thanks,
Yang
Show LessWhere is the latest WICED Studio Technical Brief located?
It would be helpful to link WICED support documents via a tab on the WICED webpage @ https://www.cypress.com/products/wiced-software
The latest Technical Brief I've been able to locate is for Version 6.2. WICED is currently at Version 6.6. Are there any major changes that would impact the Technical Brief? If not, I'll conside the 6.2 Technical Brief to be the 6.x technical brief.
Technical Brief: WICED Studio 6.2.1

Show LessHello,
I purchased a CYW920719Q40-B1 eval kits for my project recently. I am trouble in that it will always generates a series of waves after downloading official samples onto the board with WICED v6.6 which is observed via spectrum analyzer. But a new bare CYW20719 won't behave like that.
For more details is following.
1. The wave only occurs at the beginning after a hard reset.
2. The wave seens a continous wave like the following figure shows.
3. The frequency of the wave occurs in order of 2441-->2474-->2410-->2426-->2441-->2458-->2474(MHz) which likes a Tx test or self checking mechanism of the bluetooth chip I guess. However, I can't find where to define it in the programme project.
What's my assumption:
I think it is a regular action configured by the official samples. Cause I tried it in a new 20719 chip without downloading any firmwares and won't represent this problem. Besides, I have tried almost every samples in the 20719-B1_Bluetooth/apps directory. They all have the same problems.
What's my effort:
1. I have simplify APPLICATION_START( ) by commenting all of the codes in it, but it doesn't solve.
2. I tried comment the function application_start_internal( void ) in 20719-B1_Bluetooth/WICED/common/spar_setup.c, but it doesn't solve.
Could you help me to locate the key of the problem?
Thanks

Show LessI have CYBT-333047-EVAL and I need to test Audio Gateway.
I downloaded hci_audio_gateway to EVAL board and connected I2S_PCM_IN to I2S_PCM_OUT to establish audio loopback.
For Client Control, BT Headset was connected AG, and Audio Connect under AG.
An event message "HCI_CONTROL_AG_EVENT_AUDIO_OPEN" was shown.
I spoke to the BT headset but didn't hear sound.
What kind of problem can you think of?
Show LessHi,
We had encountered the same problem as the following post:
But there is no bug-fix-patch attached, can anyone tell me how to fix it ?
(sdk : wiced 6.4)
It's urgent, thanks!!!

Hello,
EZ-Serial Firmware provides commands for customizing Advertise Packets.
gap_set_adc_data (SAD, ID=4/19)
The default Advertise for CYSPP is Flag-[128bit Service UUID]-[Manufacture]-[Local Name].
Can I customize this [Service UUID] using the SAD command?
*Since the UUID of Advertise and the actual Service UUID are different, I think it is NG as BT Spec.
Best regards,

Show LessI have tested connection of HID Device using CYW20706 in 6.2 version of wiced studio.
but, when i test the connection between CYW20706 and my laptop, i found the connection is different by LMP version.
i have used the HID Device that is provided from wiced studio sdk.
The laptop of certain LMP version is connected at first attempt to connection. other cases can not connected.
who know why the connection is different each LMP version?
i attached the logs each LMP version. please could help me anyone?
Show Lessi have test the connection HID Device with my phone. The case of test is as below.
- Chipset & EVK : CYW20706 & F1DC2076 EVB (made in F1media)
- WICED SDK version : WCIED 6.2.1
- Test application : HID Device
and my test condition is as below. it is aging test.
android: power on → inquiry → connect to CYW20706 → connected → 30 seconds idle → reset
CYW20706: power on → paring enable → ready → connected → idle → disconnected → wdog reset
it is disconnected after about 37 test.
i attached log each case of connected normally and disconnected.
