I want a bluetooth module that supports A2DP and SPP profiles to be used simultaneously. I'd like to have a single bluetooth solution that can stream music while transmitting UART data using a single device. So like this:
(phone app data + music) --> bluetooth connection --> bluetooth device --> data from microcontroller to laptop/mobile
Basically I am designing a headphone which can play the audio songs from mobile/laptop using Bluetooth and at the same time I also want to transmit the serial data from headphone to mobile/laptop. so is there any Bluetooth module available for this kind of purpose?
can WT32i module suitable for this kind of application?
For this kind of design, the WT32i module is the best - it is the most advanced iWRAP-based Bluetooth Classic module, dedicated for audio applications.
It is capable of simultaneous audio and data streaming. For this purpose, let me recommend you using the newer iWRAP version, than is available at our website (it has not been released yet). There were many improvements, also with respect to simultaneous data and audio streaming.
Please create a new support request at http://www.silabs.com/Support/Pages/default.aspx ("Create a Support Request" button) and I will provide you this software image.
Thank You for the reply sir,
I have little doubt regarding this module.
which module should i buy?Because there are four types in Wt32i module.
I want to use this module for Apple Device.
Detailed information about WT32i part numbering you can find in the iWRAP software comparision document, available here:
