Please help me to put CYW920719Q40EVB-01 board in controller mode or (hci mode) where i can send HCI commnds form linux host machine

Hardware is 343026-01 running the headset app demo.

I'm trying to use the WICED uart (via external mcu host) to force a connection to a device with a specified mac address (phone in this case).  Can someone help me figure out the correct command to use for this?  I've tried the CONNECT commands in the HF, AUDIO, AUDIO_SINK, and AVRC_CONTROLLER groups, with the mac address of the phone as the payload, but none of these seem to work.  Are there multiple commands that I need to send? 

Right now I'm just trying to connect for media audio a device that is already paired, but ultimately I would like to send commands that would pair AND connect for audio a device with a specified mac address.  What is the process?

Thanks,

Ethan

Hello Cypress,

We are planning to use the CYBT-343026-01 in production, and currently programming our board is problematic. The only way to program the device on our board (successfully) is to pull pin 6 low, followed by pin 3, then release pin 3, and then release pin 6 (putting the device into recovery mode, right?). Only when this has been performed will the firmware upload from Wiced Studio work. Any other time we attempt to upload firmware the console shows a download failure, followed by a suggestion to power-cycle the device (which doesn't work).

Is there a way to make this process simpler for production runs? We don't want to add unnecessary buttons to the BOM, nor do we want to have to manually short any pins like we have been doing.

Notes:
- Our Make Target looks like _name_-CYW920706WCDEVAL UART=COM36 download (perhaps this is wrong)
- We are using a generic USB-UART device with CTS, RTS, TXD, RXD, 3.3V, and GND
- There is no external microcontroller or memory on the board

Urgent help is appreciated! Thanks,

Michael

Hi,

I cannot find any documentation or questions on connecting two boards with Bluetooth Classic.  This seems like a pretty basic use case, so I think I am just missing something. Can someone point me towards some documentation, or towards an example project? I am looking to connect with the Bluetooth Classic SPP profileand I am using the CYW920719Q40EVB-01 evaluation boards.

I have successfully run the examples in the WICED SDK as well as Cypress Academy's WB101 Bluetooth class on github.

Thank you for the help.

Dear，

When I use CYW20706, the PWM part encounters some problems. I need two PWMs, PWM0 & PWM2. They use ACLK1 & ACLK0 as the clock. Is this feasible? Now I can only use one of the clocks ACLK1 or ACLK0.

1.根据模块的data sheet 模块应该有24MHZ 的晶振和128KHZ 的晶振是吗？
2. TIME WAKE 模式时设备的RTC time 用的是内部128 KHZ 的晶振是吗？

3.当设备起来唤醒跑的时候RTC 的时间 用的是24MHZ 的晶振吗？还是 一直用128khz 的晶振作为RTC 的时间源？

4切换主频使用wiced_bool_t wiced_update_cpu_clockz()这个函数是吧？

我在API-REF-20706-A2_Bluetooth这个文档里面看见wiced_update_cpu_clock这个函数，但是在用的时候，却提示这个函数的没有定义。

请问，如果我想设置clock，我应该用哪个api
