#31189 Currently I am testing my project on a breadbord. ESP-12 is constantly sending some information by UART with baudrate set to 115200. Once upon a time (few times per hour) following message appears:

Code: Select all ets Jan  8 2013,rst cause:2, boot mode:(3,6)

load 0x40100000, len 29864, room 16
tail 8
chksum 0x8a
load 0x3ffe8000, len 952, room 0
tail 8

tail 12
chksum 0xd7
csum 0xd7
don't use rtc mem data
rl¦


It is completely readable, so ESP doesn't change baudrate during this reset. Then data start flowing again.
Cause 2 means "external reset", but simply shorting RST pin (pulled up to the VCC by 10k resistor) to the GND results in different behavior (basically bunch on gibberish sent displayed by terminal).
What may be causing that kind of "external reset"? Should I blame breadbord?
