CC2564: Simultaneous BLE peripheral and BT master roles

Brian Peavey

Part Number: CC2564

I have an IoT project for a client where I need to connect to a phone as a BLE peripheral. While connected to the phone over BLE, I need to scan for a new connection to a Bluetooth Classic device, connect, and communicate with this device. Does this module (or any of your other dual-mode modules) support simultaneous BLE and Bluetooth Classic connections?

Thanks!

Yes, dual mode with BLE and BT classic are supported with CC2564C.

Thanks

Thanks for the quick reply Hari!

How is the radio configured if it has to handle both protocols at the same time? BLE has 40 channels at 2MHz spacing and classic has 79 channels at 1 MHz spacing. My assumption was that dual-mode capable modules could switch back and forth between BLE and classic, but could not operate both at the same time due to how the radio is configured.

Could you point me to any example code that implements simultaneous BLE/classic operation?

Thanks!

That is correct the radio is time shared between the BLE and BT.

Please check SPPLE demo in the demo guide:
