Studio Bluetooth Forum Discussions

I have a customer that would like to be able to do the following with the 20706 or a 343026 module:

1) Use the 20706 in A2DP SOURCE mode

2) Pair to 4 different headsets saving link keys for each of the headsets

3) Keep connected to each of the other 3 headsets while streaming music to one.

The concept is that they do not want the connection to be dropped as this could lead to the headsets turning off after a timeout when they do not have a connection.  They would like to avoid this.  They would change the destination headset by watching for a button press with the 20706 and then stopping music to one headset (keeping a connection) and then streaming to another.

I know that we can do something like this with BLE where we could keep 4 connections active and only move data on one of them, but I'm not sure there is the same capability with Classic BT on the 20706.

Looking for any suggestions on how to do this.

Thanks,

Corey

I'm working with cybt-343151-02 module. How to transmit and receive data through hci uart in this module in wiced ide? Is there any other way to interface this module with arduino to check basic communication??

Hello

Sorry, please resume the discussion below.
<https://community.cypress.com/thread/51536>

I tried passkey pairing with 43438 as Central using a device with a control to set a fixed passkey on the peripheral side, but it did not work properly.
（Peripheral equipment has a track record of operation.）

After (Bluetooth status events: BTM_PASSKEY_REQUEST_EVT) is issued, event issuance stops and (Bluetooth status events: BTM_PAIRED_DEVICE_LINK_KEYS_UPDATE_EVT) is not issued.

Is there no problem with the usage in the attached source code?

Hi  all:

     as we know, we can debug the code  by  the  print message of peripheral uart  port. however sometimes  the peripheral uart port  becomes  unreliable, there is no

   print message output.   I want to know if I can debug the code online  by use some tools for example  Jlink, SWD.

   the development  environment is  wiced studio and the develop platform is CYW20735!

thanks!

hi there,

I am attempting to install WICDE studio on my MacBook, but the results are a bit different than listed in the instructions, here:

WICED-Studio 6.4.0 Installer (OSX)

OSX says "the installer cannot be open".

Has this been tested yet on 10.15.3?

thanks,

I use WICED 6.4 hci_iap2_spp sample code run on EVB 20706, and test APP

in iphone to send about 2MB data to EVB.

However, I noticed there are different iAP2 data rate on different iOS and/or iPhone

Current test result on hci_iap2_spp

iPhone 6s plus, iOS:11.4  ~36KB/s

iPhone 11, iOS:13.3        ~110KB/s

iPhone 6s plus iOS:13.1 ~110KB/s

So I conclude that iOS version is account for the difference in data rate

Is anyone have experience or knowledge in a similar test?

Thank you!

Hi Everyone,

In one of my product i use Bluetooth to connect network master with few slaves (piconet). For last few years i used to use LMX9830 but its rather old and has few

1. devices which work continuously delivering stream of data
2. devices which generate short events

LMX9830 has problem with second type because its buffers architecture delay events from 10ms to 30ms. I hope, that BT 5.0 with its Low Energy can better handle this type of communication but i still need SPP working parallelly for first type of devices and because of backward compatibility.

Is Cypress has any product fulfil my needs?

I was thinking about CYW20719 but i found this: 20719 Multiple Simultaneous SPP Sessions

Could you advise me something?

Best Regards

Wojciech

Hello Sir/Madam,

  Kindly guide us to generate an A2DP sink and A2DP Source profile.

Development environment:

Windows 8.1 pro

Platform: cyw920719Q40EVB-01

IDE: Wiced Studio 6.2.1

We want to test an audio profile for the BLE device.  We want to explore how it works. Suggest an example code or document for it.

We had tried to generate a customize profile using wiced designer studio.

We can see A2DP profiles in the Service Discovery tab  Only by selecting "Dual Bluetooth mode"  in the device settings tab.

But we see nothing in the CySmart mobile app.
