Hi guys,
I have an ESP-01 module which I want to use with hc-sr04. I first tried to upload the blink sketch but got this error: esptool.FatalError: Timed out waiting for packet header
I have connected 3.3V to VCC and CHPD, GND to GND and GPIO0 and RX/TX of FTDI programmer to TX/RX of ESP-01.
Did you do a search for "esptool.FatalError: Timed out waiting for packet header"? I know that I have seen this problem posted on the forum before, but since I don't use ESP8266 much I do not know the solution.
Look for a tutorial. It's not enough to just connect the pins that way. You have to switch the signals in a certain sequence to get it into code upload mode.
The ESP8266 Beginner's Guide may help.
