- Sun Aug 07, 2016 12:12 pm #52423 I still seem to have the same issue. Admittedly I haven't power-cycled since the problem last developed.

I have added WiFi.persistent(false) and have tried RF_CAL and RF_NO_CAL

Which is the correct one to use - RF_CAL? Does CAL stand for "calibration"?

- Sun Aug 07, 2016 1:54 pm #52429 There is no certainty that your problem is coming from the (maybe) missing calibration at wakeup.

rf_cal does the calibration every wakeup
rf_no_cal skips the calibration every wakeup.
rf_default does the calibration very n-th wakeup, n=(byte 108)

- Sun Aug 07, 2016 11:31 pm #52445 Hi,

I still have the same issue. I have changed my deepSleep calls to:

ESP.deepSleep(SLEEP_TIME, RF_CAL);

But if I take the device out of range of the WiFi for a few cycles, and then bring it back, it continually fails to reconnect.

Unless anybody can suggest any alternatives, I will keep trying combinations I guess.
