How to use CSMA or LBT on EFR32?

Hi,

 

How to configure and use CSMA or LBT properly?

I'm using EFR32 and RAIL stack with proprietary protocol.

 

My intent is to avoid or reduce packet collision.RAIL, EFR32

 

 

Thank you in advance.

Hi Denis, You can find latest RAIL documents in the install folder of the Gecko SDK suite. The RAILtest sample application demonstarates the usage of the related RAIL functions. See details about CSMA and LBT in section "Clear Channel Assessment" of C:\SiliconLabs\SimplicityStudio\v4\developer\sdks\gecko_sdk_suite\v1.0\protocol\flex_1.1\documentation\RailTestUserGuide.html See also the RAIL API document at file:///C:/SiliconLabs/SimplicityStudio/v4/developer/sdks/gecko_sdk_suite/v1.0/protocol/flex_1.1/documentation/API_RAIL_HTML/group___pre-_transmit.html#details

Tamás,

 

Is able to use CSMA/LBT under Sub-GHz (915MHz) ?

I'm not sure, but I saw that this feature is only available for 2.4GHz.

 

Regards,

Denis
