Other Parts Discussed in Thread: CC2564MODAEM
Tool/software:
We want to add Bluetooth microphone functionality to an existing product.
We are considering the cc2564c. (https://www.ti.com/product/CC2564C)
The idea is to use add a cc2564c to the existing PCB and use it to transmit audio from a PDM microphone to a standard bluetooth classic speaker.
We have the CC2564MODAEM evaluation board (https://www.ti.com/tool/CC2564MODAEM)
We don't want to add another MCU to run a complete bluetooth stack (for cost and space constraints) so we want to determine if it's feasible to do everything using only the HCI commands.
I found this document listing the vendor specific commands (https://www.ti.com/lit/an/swra751/swra751.pdf?ts=1726510485894)
On page 1 it says the cc256x supports HCI commands specified in the BT Core 4.1 specification Volume 2 Part E
4.1 is quite an old version, is this correct for the cc2564c?
Is there a document that summarises ALL of the commands that the CC2564c supports?
Here's what we need to do.
- Connect a microphone and transmit audio to a classic Bluetooth speaker.
- Control the cc2564c using HCI commands from the existing nrf52840 over UART
- Connect the microphone to the cc2564c
- Store pairing keys on the nrf52840.
Any help or advice is greatly appreciated.
Kind regards,
