Studio Bluetooth Forum Discussions
Hi All,
I have created a the usecase demo for Home Garden Kit with Bluetooth MESH.
In this demo 4nos CYBT-213043-MESH kit is used as below
1. LIGHT control with PIR and Light Sense
2. Irrigation for Plants
3. Door security and control
4. Remote control with CAR Keys.
more details and code will be shared via electromaker.io & embedded.club
It was short time so some minor changes only i could do it with Android Apps. ( Added Cloud support for Whatsapp messaging via twillio )
I thank Cypress Community for support and quick response MichaelF_56 DheerajP_41 AnjanaM_61

Show LessDear Sir,
当我们使用 20706 HCI UART RAW mode 测试流控时,我们现在遇到的问题是:
当外部处理器大量给20706模块串口发送数据时,在多次触发wiced_tranport_data_handler_t回调函数后,我们应用层的储存数据缓冲已经没有空间继续存储串口来的数据的情况下,回调函数wiced_tranport_data_handler_t再次触发,我们在wiced_tranport_data_handler_t函数中执行了“return 0;”(当回调函数传递的数据可以被存储下来时,我们都是返回的“return data_len;”)。
在执行“return 0;”后,问题来了,wiced_tranport_data_handler_t函数永远不再被触发了,现在我们需要解决的问题就是,我们应用层储存数据缓冲有多余空间后,如何让wiced_tranport_data_handler_t函数再次触发,继续接收串口数据,需要调用什么函数或进行其他那些处理?
不知我上面的表述,你是否理解了我们现在遇到的问题?我们最近也研究了整个开发包,但是关于WICED_TRANSPORT_UART_RAW_MODE的使用说明实在太少,更没有看到相关的使用实例代码,网上也查不到相关问题的解决方法,所以这个问题也一直还没有解决。
BR,
Cloud Chen.

Hi,
I am trying to set up a Bluetooth connection using the CWY920819 board which can initiate a call through the connection with a connected phone. I saw that this may be possible through the HCI_audio_gateway, but I am struggling to get that setup. Is it possible, and is there a reference I can use to do that? I do not need audio routing, just a call initiation.
I was working with the hci_audio_gateway example for the 920721 but the wiced_bt_rfcomm.h file is missing the wiced_bt_rfcomm_init() function, which I saw in another forum is necessary. So perhaps getting that source code is all that is needed? If so where can I get that?
Thanks,
Ryan
Show LessHi There,
do you know if Cypress has a BLE module with a total thickness less than 1.3mm?
We had an inquiry where the maximum thickness needs to be 1.5mm
Thanks!

Show LessHi All,
I have created a small basic demo for MESH client-server communication. In this demo two nodes (CYBT-213043-MESH)
publishes the data to client (CYW920819EVB-02) for every seconds. The OLED displays the Temperature and Light levels. User switch is used
to switch between two screens.
more documentation/code to follow. via embedded.club
The working video is here
Thanks

Hi,
I custome a FW, device should advertise and scan function. I downlaoded my customed FW to two CYBT-343021-01. I called them BT-1,BT-2.
In my thoughts, BT-1 and BT-2 can scan each other. But they can not see each other(For example, BT-1 should scanned the BT-2's address, but no. And BT-2 cannot scanned BT-1's address). I don't know why. Please check my attach file.
Show LessHi Cyperss
We change " snip.bt.a2dp_sink-CYW920706WCDEVAL download " to " snip.bt.a2dp_sink-CYBT_343026_EVAL download UART=COM12 " for CYBT-343026 module in WICED , When bt connects and plays music, We found that the volume is unstable Then I2S data output stops after 30 seconds , Can you tell us how to debug the issue , Thank !!
Show LessThere 2 Chips which are placed very closed to each other(Hope the BT is not interfering it ).
1. BT1 is connected to Phone : Phone(A2dp Source) , BT1(A2dp Sink).
2. BT2 is connect to CAR or Any Speaker :BT2(A2dp Source) and Car(A2DP sink).
3. The Audio is transfer from BT1 to BT2 through SAI interface.
There are various problems faced:
1. There are Audio cuts( May be the A2DP packet drop) when the music is playing through car speaker(Only in BMW and Minicooper).
2. If A2DP is connected for the BT2 and we play music on the Speaker of BT1 then also the cuts are heard only with BMW and MINI.
3. If BT1 is connected without BT2 then there is no cuts on the speaker of BT1.
What could be the reason for the Audio Cuts that too only with BMW and MIni.
1. Is it gonna be buffer Size of DMA.
2. Is it gonna be buffer Size of Profile intialization.
3. Is there any way we can increase the Strength of the Bluetooth Module.
Show LessHi,
I want to add function to chage mac address and I know there are many ways. I want to use wiced_bt_set_local_bdaddr API to set address. My question is that is this API can call any time, even though FW run a while then to set?
I use CYBT343026-01 EVAL board. I test two ways.
1. CALL API before wiced_bt_dev_read_local_addr(bda)
result: address is changed
2. CALL API after wiced_bt_dev_read_local_addr(bda)(receive uart cmd then do call the API),then reset device
result: address no change
Show LessHello everyone,
I'm starting now with Cypress modules and right now having a hard time with debugging.
I'm trying to debug cybt-213043-mesh kit directly with the usb port.
I saw that this kit has a "double usb", one for programming and another for debug. I'm trying to debug over the peripheral port but not's happening, when i open it nothing is shown to me.
I also programed the kit with the usb debug enabled:
And when i try to program the board with the option "BLE_HelloClient Build + Program + Debug" a error is shown:
If i try to "debug attach" another error happens:
I have to install something to run the debug? What's the problem?
Thanks,
