- Wed May 20, 2015 9:58 am #17965 So...do I need an USB-Serial programmer with reset pin to use with ESP8266 module?... I'm asking because I have two different programmers (CP2102 and PL2303) and both of them have no RESET pin... Also, when I try to upload a code using a CP2102 I got this message:

Code: Select allwarning: espcomm_sync failed
error: espcomm_open failed
