Part Number: TM4C129XNCZAD
Other Parts Discussed in Thread: CC2564MODA

Hello,

I am working on TM4C129XNZAD microcontroller as the baseboard, by using CC2564MODA Bluetooth module I need to communicate with multiple Bluetooth like NRF Dongle, Tablet and Remote control. The Control PCBA Blue tooth chip to communicate with dongle every 10 ms and with tablet every 20 ms, there should be no packet drop for this communication. Kindly please help on this, how to interface these modules.

Thanks

H Jansi,

What kind of Bluetooth communication do you need? Is it Bluetooth classic (BR/EDR) or BLE?

The CC2564MODA can support multiple Bluetooth connections; however, this controller no longer can be qualified for new Bluetooth designs as it is withdrawn. Is your design existing or new?

Best,
Jacob

Thanks for replying..

Yeah my Bluetooth is BR / EDR only. I need to communicate CC2564MODA with three Bluetooth interface, can you please help how to implement in program.

Thanks

Hi Jansi,

I'm going to assume you are aware that you are using a withdrawn Bluetooth controller and stack, meaning you cannot qualify this product with the Bluetooth SIG.

The Bluetooth stack for the TM4C is available here. This stack will run on the TM4C host to send commands to the CC2564MODA and communicate with other nearby Bluetooth devices. Since you can only run one instance of the stack on the MCU, having 3 connections will be difficult to support due to bandwidth constraints. What type of Bluetooth profile are you planning on using (sending data, streaming audio, handling phone calls, etc.)? The TM4C stack has several demos that support these use cases.

You may want to refer to the CC2564 HID/HFP/SPP Integration App Note which provides some information for integrating three different demos together.

Best,
Jacob
