Tool/software:

Hi,

We can have a specific configuration requirement to be implemented on CC1311. Please check and comment on the below configuration possibility in CC1311.

FEC: 1/2 rate convolutional coding

Preamble (4 bytes): AAAAAAAA

Sync Word (4 bytes): 91D391D3

Whitening : Enabled as in CC1110

Deviation: 3.707866 kHz

Channel spacing: 363372.8027

Manchester Encoding : Disabled

Modulation: 2-FSK

Center Frequency : 400.2 MHz and 450.1 MHz

IF Frequency : 158.203 kHz

Frequency Offset : 0

Thanks,

Theiv

Hi Theiv,

You can use SysConfig or SmartRF Studio to configure your settings. Please see this training. Let me know if you have any questions:

Hi Marie, As per the table attached here, it is mentioned that FEC is supported in Long Range mode along DSSS. In our case we would like to have FEC without DSSS and with a sync word customization. Please let me know if it is feasible with CC1311P3

Hi Theiv,

You can configure FEC in the setup command, in the formatConf parameter. Please see the TRM Table 25-175.

Cheers,

Hi Marie,

In Our requirement, we do not require DSSS and we need configurability for Sync word.

In long range mode, we see restrictions in these. Please suggest the configurable option to choose a mode where we can disable DSSS and have 32bit configurable sync word along 1/2 rate Convolutional coding.

Thanks

In the LongRange PHYs, the DSSS can be set to 1 and the 32 bit sync word is configurable.
