Our Application is wired Intercom, and we have wires(audio connections) running between Central station to Extensions, and we would like to replace these audio connection wires with Bluetooth wireless connection, I am wondering if we can replace the wire by putting two Blue-tooth modules (CYBT-343026-01) one at the Central station and other at Extension point.
I am not really sure if that is feasible or not. Does these modules talk to only Host devices (like smart phone)?
can we establish wireless audio connection between two Bluetooth modules(CYBT-343026-01) without the help of any smartphone/any other host? Please let me know your thoughts about it.
Solved! Go to Solution.
Thank you for the response, I am able to find A2DP Sink example, but I found only one A2DP Source Example, that is Smart Watch and they are using Apple Media Service (AMS) and Apple Notification Center Service (ANCS). Could you please recommend any A2DP Source example without Apple Media Service (AMS) and Apple Notification Center Service (ANCS)?
Thanks again for your help and I look forward to your reply.
Hi @NaAm_1281831 , the audio watch example is highly modular, you can remove services that you don't require. We would be able to help you if you have any questions in implementing A2DP source example using Audio watch as reference.
I am thinking of using the Bluetooth Module CYBT-343026 on CENTRAL Station and EXTENSION units. I see that this module also supports BLE.
Is it possible to broadcast music from Central station to all Extension units? Please let me know.
Hi @NaAm_1281831 ,
Audio is supported only in BT classic. LE audio is not supported in CYBT-343026 . Also it is not possible to broadcast audio to multiple peer devices. It is a one to one connection.
I would like to verify the A2DP sink option by quickly ordering the CYBT-353027-EVAL and the TI’s CODEC IC TLV320AIC3120 (Demo board TLV320AIC3120EVM-U Texas Instruments | Development Boards, Kits, Programmers | DigiKey)
I would to the necessary wire hookup between these demo boards, Could please tell me if the above mentioned TI CODEC IC’s I2S interface is compatible to the CYBT-353027?
I look forward to your reply.
Hi @NaAm_1281831 ,
There is no particular list of 20706 supported codecs. There are no limitations of HW or SW side of module to connect any codec. However, the i2s & i2c pins are multiplexed on 20706, therefore you should go for a codec which can be interfaced via a SPI interface for configuration. Also, you will have to develop the codec library on your own.
