CC2530: Zigbee and Bluetooth co-existence

Part Number: CC2530
Other Parts Discussed in Thread: CC2540, , Z-STACK, SIMPLELINK-CC13X2-26X2-SDK, CC2652R, LPSTK-CC1352R, LAUNCHXL-CC26X2R1

Hi,

As there are multiple solutions for single SoC WLAN+BT, there is a straightforward question:

What is the best way to include Zigbee (for example with CC2530) together with BT (for example with CC2540).

1.) Is it possible with TI's devices to harmonize these two components with a single medium (antena)? (3-Wire Coexistence Interface?)

2.) Or better, is there any SoC which can provide these two functions (Zigbee+BT)?

Any document, resource, or extra technical information would be very useful.

Thank you.

Hi kjla,

If using a CC253X device then your best option is to control a ZNP over the UART NPI and MT interface using a BLE host processor. You can reference the Z-Stack documentation for this method.

My recommendation is that you consider using the DMM available on the SIMPLELINK-CC13X2-26X2-SDK, specifically consider the CC2652R for your purposes: http://dev.ti.com/tirex/explore/node?node=AHZhd1QS7-01t9SlfC9ncg__pTTHBmu__LATEST

This updated SimpleLink device includes quarterly SDK updates, new LaunchPad development boards (LAUNCHXL-CC26X2R1 or LPSTK-CC1352R), and advanced learning tools included in TIRex such as SLAs and User's/API/Migration Guides.

Regards,
Ryan

DMM seems quite promising.

I'm currently using the CC2530 with Z-Stack which provides information to the higher level application through UART.

If I migrate to something you mentioned (CC2652R), can I still use my higher level application, or it will needs to be refactored? (It currently uses the Z-Stack as-is).

Regarding BLE, I need a functionality which is supported by the Linux Kernel: this could be achieved easily with CC2540 via USB:

The system can control it via HCI, and I can use standard bluez tools like the gatttool.

Is this something that easily achievable with your mentioned SIMPLELINK-CC13X2-26X2-SDK?

Thank you!

The CC2530 supports a 8051 core and OSAL design so the application will need to be modified for the M4F core and TI-RTOS support. This can be further understood through the CC253x to CC13x2 or CC26x2 Migration Guide: http://dev.ti.com/tirex/explore/node?node=ABVzex.8S03NWa2SW7sUwA__pTTHBmu__LATEST

I don't think HCI control will be an issue with the CC2652R (but you can provide further questions on the BLE forum): http://dev.ti.com/tirex/explore/node?node=AOimuSWjap.4RuDbcp7OqA__pTTHBmu__LATEST
