Re: nmcli radio off connected to ModemManager power state low

["c lobrano gmail com" <c lobrano gmail com>]

I'm sorry, I think I explained myself wrong.

CFUN=4 is ok for radio off, I wanted to say that some plugins might not use CFUN=4 for "power low".

In Telit modem, as example, I might use CFUN=5 "mobile full functionality with power saving enabled" and CFUN=4 for power off, but doing so "nmcli radio off" won't shut down the radio (without rfkill).

Why do you need the modem to be totally off?

In power low I could expect that the modem goes in some kind of power saving configuration but still connected to the network, it really depends on the modem capabilities, and when rfkill is not available, the modem is only set in power low, which may not be the same as radio off. I totally understand the problem though, modems that use CFUN=0 to power off are not listening to any command to put them ON again. I will look better to rfkill, but I still see a possible misunderstanding between power low intended as radio off and power low intended as power saving.

Is there any case in which CFUN=4 doesn't mean radio off? Maybe we got it wrong.
