I think by default the LED is turned on (this LED is on PIN 14 in case you want to play with it).Įsptool.FatalError: Failed to connect to ESP8266: Timed out waiting for packet header I am still having problems sometimes uploading to the ESP8266, sometimes it feels like just trying over and over until it works. This will then enable a new sketch to be uploaded. When dip switch 7 is ON I believe the ESP8266 does some kind of factory reset when you reset the board. Setting reset method to no dtr, no_sync also did something for me. Maybe throw in an upload without pressing reset before. Again pressing the reset before uploading. If it looks like it is not working, just wait for it to throw an error and try again. After you upload your code I believe you have to put dip-switch 7 to OFF so that your sketch remains after rebooting the board. Now, before uploading anything you have to reset the board with the red reset button before pressing upload in the IDE. I downloaded the ESP8266 community here board manager and selected Generic ESP8266 module. When programming the ESP8266 you have to set dip-switches (5,6,7) ON and (4,5) OFF. If it shows an error just try again and play a bit with the timing of pressing the reset button. If these show up you press the red reset button. Now, when you hit the upload button you wait for the first few (red) lines (overriding baudrate for me) of the upload to show up in the console. Here it helps if you go to Arduino->Preferences and set Show verbose output during: upload. When uploading a sketch it gets a bit tricky. Make sure you select the right COM port, you can check by unplugging the USB from your computer and putting it back in again to see what COM port shows up (you have to exit the menu in between). Now in the Arduine IDE I select the Arduino UNO as the board.
When programming the ATmega you have to set dip-switches (3,4) ON and (5,6,7) OFF. However, I cannot verify this, I believe it worked for me without doing this but honestly, the thing is still a black box to me. I read somewhere that when changing dipswitches you have to press ESP reboot. And for USB communication you have to choose either ESP8266 or ATmega.
USB ESP8266 0000111 (Update firmware or sketch)Īs you can see, the first two switches enable communications between both chips. Communication mode is set using the dip switches as follows:
