Other Parts Discussed in Thread: CC2564C, CC2340R2
We want to add A2DP audio source functionality to our existing product.
We need to send microphone audio via Bluetooth to off-the-shelf bluetooth speakers. Connecting to something like this. Mono, low bitrate is fine
A2DP. and RCP profiles to allow speaker to control play/ pause with our device only exposing one button to do pairing.
Minimal development effort if possible, ideally you have an example circuit and firmware example that we can work from
I found this which looks interesting https://www.ti.com/tool/BOOSTXL-CC2650MA
And this https://www.ti.com/product/CC2564MODA
Are there other options that I should look at?
Good TX power, low power usage, compact PCB footprint are important.
The current product also incorporates an nrf52833 with CODED_PHY periodic adverts (12 per second) to send other data, so we are either considering a companion IC that just acts as the A2DP audio source, with its own antenna, or an all-in-one solution that can do dual mode A2DP with simultaneous CODED_PHY periodic adverts. But obviously this would probably entail substantially more development effort, which we really want to avoid.
I'd like to know what you would suggest, any help is appreciated.
Kind regards,
