TI-15.4-STACK-GATEWAY-LINUX-SDK: Question on CONFIG_CHANNEL_PAGE_9 vs. CONFIG_CHANNEL_PAGE_10

Part Number: TI-15.4-STACK-GATEWAY-LINUX-SDK

I am using TI-15.4 Stack Linux SDK (TI-15-4-STACK-GATEWAY-LINUX-SDK_4.30.00.06) for SLR.

Accidentally we mis-match CONFIG_CHANNEL_PAGE between CC1312 sensor and Linux collector.

SLR's CONFIG_CHANNEL_PAGE should set value 10 for SLR, but we have set sensor to value 10 and collector to value 9 accidentally.

However, we have tested for some period and not notice this issue because sensors can talk to coordinator well.

My questions are (1) any impact (e.g. distance range or receiver sensitive) when mis-matching CONFIG_CHANNEL_PAGE between sensor and collector? (2) why they can talk?

Thanks.

Regards,

Peter.

    Hi, 

    The CONFIG_CHANNEL_PAGE configures which channel page to scan.

    You were able to establish connection and communicate by accident where you were using the same center frequency and channel on both devices. This is not recommended. Please use the recommended CONFIG_CHANNEL_PAGE 10 when using SLR.

    Hi Siddanth,

    Thanks for confirmation. I will use PAGE 10 for SLR for sure.

    But just curiously about two things I asked: 

    1. Any impact when both sides nor use the same PAGE? Or no impact? Why?

    2. Why they can talk as PAGE 9 and PAGE 10 support different modulation schemes? Which modulation is used in SLR (5 kbps)?

    Thanks again.

    Regards,

    Peter.
