I am sure the current is correct, the esp is booting and running happily regardless of mode so I don't think I have a supply issue.
I am using an el cheapo multimeter on current mode with a chunky rectifier across it in case any current spikes cannot be handled by the shunt properly.
my notes ..
monitored on shitty multimeter
current ranges
200uA 1k ohm
2000uA 115 ohm
20mA 22 ohm
200mA 10.3 ohm
rectifier across meter in case of spike currents. it will not always boot in 200uA mode but I can switch it down to that range while in deep sleep.
unmodified ESP01, power led still enabled
current sketch is ..
current sits on and around 60mA until it hits sleep.
and this outputs ..

added a wifi_station_set_auto_connect(0); to my sketch just to make doubly sure that no wifi was happening that I can think of..
still no dice, 64mA no matter what sleep option selected.
also updated to the latest arduino build..
any thoughts people ?Code: Select allshould be 15 mA constant. Are you sure your measurement is correct. Can you log on to your router and verify that ESP is indeed not connected.ESP.deepSleep(SLEEPTIME * SECONDS, WAKE_RF_DISABLED);
