- Wed Nov 05, 2014 3:02 am #2257 Using an arduino uno's 3.3v output. The usb offers ~500mha. The arduino doing nothing (mostly) does not take that much.
gipmad was having a problem related but it seems it was fixed all of the sudden.

The module worked with AT commands and scanned and found the networks.
Everything works with this firmware except the wifiscan which triggers a reboot. I am suspecting the watchdog but did not get a change to read the previous reboot reason yet.

try resetting the device with GPIO0 as I've written earlier; try to use 2 arduino supplies in parallel; add caps; try to build a single bin file padded with 0xFF and flash that; post a serial log.

I am not saying it is the power supply for sure, but when i tried to power the esp from anUNO i had reboots with specific AT commands. I suspect the WIFI scan is running the radio at full power and causing the reboot.
