Original question:

LAUNCHXL-CC1352P: LAUNCHXL-CC1352P1 and LAUNCHXL-CC1352R1 compatibility

LAUNCHXL-CC1352P: LAUNCHXL-CC1352P1 and LAUNCHXL-CC1352R1 compatibility codes OpenThread

Part Number: LAUNCHXL-CC1352P
Other Parts Discussed in Thread: LAUNCHXL-CC1352R1, , CC1352P, CC1352R, SYSCONFIG, SIMPLELINK-CC13XX-CC26XX-SDK

I want to use OpenThread with LAUNCHXL-CC1352P1, but the Resource Explorer only shows examples of codes to LAUNCHXL-CC1352R1.

Since the difference between these Lauchpads are the presence (or not) of the additional 20 dBm PA, can I use the code from CC1352R1 and launch it to my CC1352P1?

Thank you.

    Hello Eduardo,

    I do not recommend using the CC1352R project as the pin designation on this device slightly varies from the CC1352P due to the PA which will cause run-time issues.  Instead, please use the LAUNCHXL-CC1352P-2 Thread projects.  Since the PA matching circuit hardware on the LAUNCHXL-CC1352P1 is optimized for Sub-1 GHz operation, whereas the LAUNCHXL-CC1352P-2 version supports 2.4 GHz instead, please make sure to use an output TX power of +5 dBm or less inside of the SysConfig file's TI-OpenThread -> RF module.  Given that OpenThread only operates at 2.4 GHz, this will allow the normal output path (i.e. non-PA) to be used.

    Also, please be aware that future versions of the SIMPLELINK-CC13XX-CC26XX-SDK (i.e. past v7.10) will not include the OpenThread stack or resources.  Instead, it will be hosted on TI's ot-ti Github repository.

    Regards,
    Ryan

    Hi Ryan,

    Thank you for your suggestion, I'll take a look at LAUNCHXL-CC1352P-2 OpenThread projects!

    You said "OpenThread only operates at 2.4 GHz", it means that it is not possible to use it with Sub-1 GHz? Is it a compatibility issue? OpenThread is designed only to operate at 2.4GHz or is there any other reason?

    I appreciate your help!

    This is determined by the Thread Specification and is not determined by TI.  You can learn more from the OpenThread Group and Thread Support.

    "The Thread Specification uses the IEEE 802.15.4 [IEEE802154] PHY (Physical) and MAC (Media Access Control) layers operating at 250 kbps in the 2.4 GHz band for link layer communication. The IEEE 802.15.4-2006 and IEEE 802.15.4-2015 versions of the specification are used for Thread."
