Using Wemos D1 mini Pro V1.0.0 from 3x AA batteries it has been working just fine for couple of months and still works ok
I decided to make couple more and made the same hw but this time I got
Wemos D1 mini Pro V1.1.0, otherwise all the hw parts etc are the same.
Now I have problem that the waking up from external trigger works only when I have Arduino SDK
and serial monitor enabled, then it works just fine.
If I just use batteries or 5v usb charger, it does not wake up from deep sleep.
Arduino sdk 1.8.3 it worked fine on serial monitor and for sdk 1.8.5 I needed to set from the board.txts file DTR and RTS low
So seems that when using 5v usb charger or 3xAA batteries the DTR and RTS are left high and the wake up trigger does not work.
I could not find what changes are done on the v.1.0.0 vs v.1.1.0 board that could make difference, or it is just different batch.
D1 (GPIO5) and D2 (GPIO4) works just fine when waking up from light sleept etc,
only the D0 (GPIO16) and RST has this problem.
Is there something obvious I'm missing?
