ESP8266 Community Forum

- Mon Jun 22, 2015 3:56 pm #21275 I used esptool.py with a USB2UART converter directly (costs 1.15$ per pcs, just got two new CH340 ones as backup today, they can be switched to work with 3.3V or 5V, tested and both work perfectly), cannot say whether you can use esptool.py "through" arduino.

- Wed Jul 01, 2015 3:46 am #22131 So I've used an arduino board(without the(Microcontroller) as an FTDI, and using Minicom I've been able to see the data my esp8266 is sending me, which is trash. I've dowloaded pyserial and have made sure it works, ad myesptool.py. When I try to run the program it waits a little and it tells me that it couldn't make the connection. How could I troubleshoot this in order to find what's wrong. BTW when I put the GPIO0 pin to ground, the esp8266 starts sending me trash, won't this be a problem if I want to send info to it. I've also changed the baud rate of my usb port, but it didn/t change anything.

Thank you.
