LAUNCHXL-CC1352P: How do i use both Bluetooth and Sub-GHz (simultaneously or swapping Stack) with CC1352P1?

LAUNCHXL-CC1352P: Is it possible to use DMM (RF + BLE) with Open Thread?

Part Number: LAUNCHXL-CC1352P
Other Parts Discussed in Thread: SYSCONFIG

I am looking to build a project where I wish to use TI-RTOS + Open Thread with DMM.

I started building an empty project and opened SysConfig to configure the necessary setups. Is there a basic setup I can start through or some guide on how to implement these configs?

I know there are project examples in the Resource Explorer but they are more simple and show these resources working separately.

    Hi Eduardo,

    Please see the information contained in this prior E2E thread: 

    TI has not prioritized development of a Thread + BLE DMM solution.  Developers are given the ability to implement their own custom DMM solution using the TI DMM User's Guide and DMM SimpleLink Academy Labs as references.  You can also consider a two-chip solution as time sharing may not be optimal if these stack solutions each require a majority of the radio's access time.

    You could also consider using or referencing Matter projects since these already incorporate BLE commissioning and Thread network communication in a single solution.

    Regards,

    Hi Ryan,

    I'm sorry, maybe I misunderstood something but I got a little confused.

    Since OpenThread is designed to operate at 2.4GHz, how is it possible to commission Sub-1 GHz and 2.4GHz?

    Thank you!

    OpenThread and BLE are both 2.4 GHz.  What other radio protocol are you attempting to implement?

    Okay, DMM is possible if both networks are at 2.4 GHz.

    I would like to implement an IoT project with a Border Router and some Devices acting as sensors. I have read that OpenThread already manages some issues and make developing IoT easier, but I'd like a Sub-1 GHz network to communicate these devices.

    In this project, I would use the 2.4 GHz (BLE) network with another purpose.

    DMM is possible for protocols at 2.4 GHz and Sub-1 GHz as well.  TI provides examples of BLE (2.4 GHz) + 15.4-Stack (Sub-1 GHz) DMM and it is theoretically possible to implement a Thread (2.4 GHz) + 15.4-Stack/PropRF (Sub-1 GHz) DMM solution, however no specific examples are currently available.  It is not possible to implement three protocols with DMM (i.e. Thread 2.4 GHz + BLE 2.4 GHz + 15.4-Stack/PropRF Sub-1 GHz).  You will need a multi-chip solution if such a configuration is necessary.
