Unexpected external reset
Posted: Mon Oct 12, 2015 3:27 pmCurrently 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:
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?
