Studio Bluetooth Forum Discussions
Hi all,
Before put bluetooth controller in Wake-on-BLE state, I need to filter advertisement packets with device address and some specific manufacturer data .
I used 0x05 LE_ADV_PCF (LE Adv Packet Content Filter) Feature Selection command but no success .
you can see in this example , I try to filter with XX XX XX XX XX XX address but command doesn't success (log with btmon)
< HCI Command: Vendor (0x3f|0x00e9) plen 14 | #12 [hci0] 112.685279 | |
05 00 XX XX XX XX XX XX 00 20 00 00 00 00 | ....m.... .... | |
> HCI Event: Command Complete (0x0e) plen 5 | #13 [hci0] 112.688789 | |
Vendor (0x3f|0x00e9) ncmd 1 | ||
Status: Invalid HCI Command Parameters (0x12) | ||

Have you any idea please?
Show LessDoes CYW20719 support HIDOFF? The Datasheet says yes but the Power Modes App Note says no HIDOFF.
http://www.cypress.com/file/415986/download ) it says the CYW20719 doesn’t support HID-OFF. Which document is correct?
Show LessHello community,
I am attempting to drive a TFT display (160x128) using the 20719 eval board. In this document, it mentions that the chip has DMA, but that it is not accessible from WICED. It is however used in the display examples, but none of those examples will work for my screen. Is it possible to somehow use DMA or some other hardware accelerated feature to drive my display?
Show LessHello,
I have the following setup
CYW43907
------------------- (CYW43907)
WICED BR/EDR/LE host stack
HCI over UART
-------------------
.
. UART
.
------------------- (BLE HCI chip)
HCI over UART
BLE Controller
-------------------
Question:
1. My understanding is the WICED BR/EDR/LE host stack must be configured BLE-only host stack to be compatible with BLE HCI chip. How to configure WICED host stack to be BLE-only stack?
2. HCI UART driver is already available in WICED?
3. Do you have any integration guide document?
Best regards,
Xiaodong Xu
Show LessI need to use i2s and i2c interface in this board.but according to the "CYW920706WCDEVAL Evaluation Kit Hardware User Guide" i2s need to use pin A8 C7 B7 C8.so I2C should use pin E8 D8,but E8 D8 are used to connected to the serial flash.I want to know how to use I2S and I2C in the same time or it is impossible.
Show LessHi Team,
Could you help indicates how to fix the BR/EDR pairing always failed issue after unpair operation was done before?
Detail of this issue is described below.
Environments:
IDE: WICED Studio 6.1.0.85
HW: Android Phone
HW: CYW20719-B1 module
Steps to reproduce:
1. Build and download the app/snip/bt/a2dp_sink project to the CYW20719-B1 module device, and wait the a2dp_sink app started up.
2. In Android Phone device, discover and find the a2dp_sink device.
3. Click the a2dp_sink device to pair and established the connection for the firstly time.
4. After pair and connection established successfully. disconnect and un-pair the Android phone with the s2dp_sink device.
5. Turn off the Bluetooth on the Android Phone, then turn it on again.
6. In Android Phone device, discover and find the ad2p_sink device.
7. Click the a2dp_sink device to pair and established the connection for the second time.
8. Here, we found that the the a2dp_sink device cannot be paired and connected anymore.
We could see 30s timeout issue or PIN code miss-matched error when try to re-connect to the device.
Following is the firmware log that captured when the a2dp_sink firmware running with above steps:

Show LessAt page6 in CYW20705's datasheet(002-14867 Rev. *F), the header is below snapshot.
Is "CYW20702" a typo?
Is a block diagram on the page CYW20705's block diagram?

Show LessHello,
I have a dual chip setup, with CYW43907 connected over HCI-UART to a HCI BLE controller chip.
On CYW43907, running WICED studio 6.2.1 with BLE host stack.
HCI BLE chip support unlimited simultaneous ble connections, and BLE 5.0 long range (LE_Coded_PHY), and BLE 5.0 LE_2M_PHY.
I want to know if WICED studio 6.2.1 BLE stack support all these three features?
Best regards, Xiaodong
Show LessHello Problem-Solvers!
This past week we had our WICED Bluetooth Virtual Workshop, co-sponsored by Mouser, teaching hundreds of engineers how to design low-power IoT devices using Cypress' CYW20719 Dual-Mode Bluetooth 5.0 Wireless MCU. Missed it? No worries! You can now watch on-demand right here on the Cypress community. Here are the steps to follow:
1. Buy a CYW20719 Eval Kit (CYW920719Q40EVB-01) from Mouser so that you can follow along the workshop
2. Open up Alan Hawse's lab manual on www.iotexpert.com, which will provide you with all of the instructions and source code you need to complete the projects in the workshop
3. Watch the on-demand virtual workshop here: Video Link : 1640
Thanks and enjoy!
Best,
