I am trying to know when a transmission is finished without using TXMON.
Is there a standard way to do that?
In FDD mode, I am able to see the transmitted signal (it is a half-duplex channel with a slightly different LO), but I want to use a single antenna in the future with an external switch, possibly with a PA, so I am ruling out this possibility.
In TDD mode, I have to manually switch modes in ENSM (from TX to ALERT). Is there a way to make it happen automatically when the buffers are flushed?
Is reading from GPO the only way?
Thank you in advance,
