Part Number: CC1312R
Other Parts Discussed in Thread: CC110L

Could you teach me about Q1 - Q3 

Q1.How much Rx Sensitivity value is CC1312 at 100kbps / 250 kbps

Q2.How should I set the Data Rate? Can I set 100kbps / 250kbps?

Q3.Can CC1312 and CC110L communicate? Of course I use the same data rate.

    Hi,

    Please see the following for my answers.

    Q1 - The estimated values for Sensitivity at 100KBPS is around -107dBm and at 250KBPS is around -102.5dBm

    Q2 - You can use SmartRF Studio and set the Data Rate, Freq Dev and Rx Filter BW. For 100KBPS, you can set 100KBPS, 50KHz Dev, 195.9 KHz Rx Filter BW. For 250KBPS, you can set 250KBPS, 100KHz Dev, 546.3KHz Rx Filter BW.

    Q3 - Yes, they communicate. But please make sure their Sync Words and Preambles match to each other. They are different by default settings.

    Thanks,

    Hi

    May I ask additional question about your answer Q1 

    Are these values at 868MHz?

    What if it's 915 MHz? Same values?

    thanks,

    Hi,

    More or less, the performance would be same at both 868MHz and 915MHz bands.

    Please refer to the App Note SWRA588.

    Attached is the App note for your ready reference.
