Hello, I have just bought an ESP8266 ESP-01, and I want to write a program to it (from Arduino IDE with ESP8266 addon). I don't have any USB-to-serial converter, just cheap ESP-01 USB adapter form China (this one). Is there any way to upload program/firmware trough Arduino UNO? Or is there any way how to make it with the adapter?
Thanks for help

I managed to get it working (on adapter) by simply connecting GND to GPIO0 for a short time. Because of the adapter, I had to use F/M Jumper Wires to wire the ESP8266 to the adapter. If someone knows, how to program it using UNO, he can put it there, so other users will find it. Thanks

I think if you remove the arduino chip and connect tx/rx UNO to rx/tx ESP you may use like if using an adapter.

...not exactly your connector, but should provide vauable hints.
