CC254x - Gain Control Setting Status

Michael Questo

Other Parts Discussed in Thread: CC2540

Champs,

The HCI_EXT_SetRxGainCmd is used to toggled the gain of the CC2540 between Standard (-87dBm) and High (-93 dBm).  This is described in the Vendor Specific HCI command Doc in the SDK and the Datasheet.  By default this is set to standard.

Is there a way to request the current state of this device.  Is there any ability to use an intermediary mode between Standard and High?

Thanks!

    Hello Mike. No, there is no API to read the RX gain. The idea is that you would keep track of it if you set it.

    Theoretically it would be possible to use intermediate values but this would require a pretty significant modification in the controller.
