- Thu Oct 06, 2016 12:22 pm #56154 Two samples (ESP12F, Arduino 1.6.6, SDK 2.0.0) running with the radio off (WAKE_RF_DISABLED), apparently, the ADC is completely disabled too.

Sorry if this is a known phenomenon, I couldn't find it searching with the obvious keywords. Is there a way to use the ADC with the radio off?

Thanks,
Jeff

Unfortunately I'm now getting streams of "pll_cal exceeds 2ms!!!" errors when the system starts up with the radio disabled. (Runs fine with the radio on.) I see a thread on the Espressif BBS (http://bbs.espressif.com/viewtopic.php? ... 2ms#p10010) regarding that error, but it doesn't explain much.

Anyway, thanks for your help. Sideways is better than backwards....
