Hello everyone,

I was trying to re-program the demo application that came with the eval board.

Through ModusToolbox, I downloaded the "Audio-20721B2EVK02"  application.  I was able to build the "Audio-20721B2EVK02.a2dp_sink" project fine, but a few other audio projects are having compilation issues, 1 specifically "Audio-20721B2EVK02.headset"

Error:

headset_control.c:673:14: error: 'BTM_BLE_REMOTE_CONNECTION_PARAM_REQ_EVT' undeclared (first use in this function); did you mean 'BTM_BLE_CONNECTION_PARAM_UPDATE'?

         case BTM_BLE_REMOTE_CONNECTION_PARAM_REQ_EVT:

This seems to be missing from wiced_bt_dev.h.

Is this project deprecated, or is there some library update that must be done ?

I have:

wiced_btsdk release-v2.6.0 18c098e

Audio-20721B2EVK02 release -v2.7.1 7831eff

I'm trying to connect TI MSP430 series microcontroller to broadcom BLE chip(BCM20737) through UART.

The expected BLE role is very simple to send and receive message(less than max 20 byte including message and payload) between TI uC and mobile phone.

It looks so many app examples as below, but I want to find the right app for my simple message transfer application with the mobile phone.

Any suggestion would be appreciated.

Hello,

I am looking at the hello_sensor example project, and I see the call to wiced_bt_start_advertisements(), which starts advertising, and I can see the BLE device show up on a BLE scanning app.

What I am trying to do now is stop the advertising after 1 minute to try to save power if no client has connected to the device.  I do not see a corresponding wiced_bt_stopadvertisements() function anywhere.

Does anyone the API call to stop the device from advertising?

Hi there,

I want to program the 128 KB serial flash inside the CYBLE-013025 module over SWD but I'm having some difficulty getting it setup. I am able to communicate and enter debug mode on the CYW20737 microcontroller over SWD.

I downloaded the WICED Smart SDK at WICED Smart Docs & Downloads and installed the WICED Smart Eclipse IDE. I don't see any flash programming projects with a flash driver or API.

Can you tell me what I am missing?

Thanks

Hello,

What is the limit to the maximum number of GATT-proxy (phones) that can simultaneously transfer data on the BLE Mesh?  What is the maximum number of nodes that can be on the BLE Mesh.  Is this limited to memory?

Thanks in advance,

Scott

Where can I find Certifications, Test Reports and Compliance information for CYW20737L?

I see Certs and Test Reports for CYW20737S @ Broadcom CYW2073XS SiP Module Regulatory Approvals  Are these applicable to the "L" version?

I'd also like confirmation that CYW20737 is Bluetooth 4.2 or ideally 5.0 compliant. Is that information also available?

What are all the differences between CYW20727S and CYW20737L?

I understand Receive, Transmit and Sleep current for CYW20737L are roughly half that for CYW20737S.

Is there a penalty for that power savings with the L version? If no penalty, what is the benefit of the S version?

The L version has external DC-DC support. Is the power savings in the L due to losses in a DC-DC moved externally?

I am trying to implement some RF test software so I can send my product to a test house.  I need to be able to generate a continuous frequency at differing powers and modulation.  The Set_Tx_Carrier_Frequency_ARM command seems to be ideal for my needs, but it doesn't work.  Can anyone tell me the correct command sequence I should be sending using hcitool?

This is running on a headless Raspberry Pi CM3 so no way of using any GUI based packages, just the commandline.

Good morning, I tried to enable CYBT343026 bluetooth module by HCI Uart commands, but I can't see it trought bluetooth of my smartphones.

To send commands to BT module I use CyBlueTool.

I've enabled radio, set tx power, assigned name to device and bd_addr, but without success.

What did I forget?

Thanks in advance for your help.

Regards

Hi, I use cyw20719.

Where is classic bluetooth mouse or keyboard example?

Please tell me.
