USB to ESP-01 Board Adapter Modification
Posted: Tue Jun 05, 2018 9:53 amHello, I bought a esp8266 esp-01s with a relay module.
I try to program it from the Arduino IDE with a USB to ESP8266 module, using as board "generic ESP8266 module"
(I program in this way nodemcu without problems)
a) USB-to-ESP8266-Serial Developent Board like this:
https://www.ebay.es/itm/USB-to-ESP8266- ... 2749.l2649
b) esp8266 esp-01s:
https://www.ebay.es/itm/5V-Wifi-Relay-M ... 2749.l2649
An error occurred while uploading the sketch
warning: espcomm_sync failed
error: espcomm_open failed
error: espcomm_upload_mem failed
I have seen the solution on this page: you have to solder a button to put gpio-0 to GND. So it works perfectly!

"This first generation adapter doesn't have any mechanism to put the ESP-01 into Serial Programming mode which require pulling GPIO-0 pin LOW"
I hope it serves you.
