I’m using AT commands for testing LTE performance on EM7455. A very basic command is setting TX power. The command is DALSTXPWR = x,x

1. Is this documented anywhere?
2. What are the two parameters?

I see examples like "DALSTXPWR=1,10.

What is the “1”?  
Is 10 supposed to be “dbm”?

thx  
Allen

The command seems not officially supported in AT command user guide.
