Is there a fatal error failure to connect to ESP8266?
It sometimes works once, then fails. It’s not only frustrating, but really odd the way it ehaves. Yes, it still failed, it worked once, I removed the ESP package in Arduino15 folder, loaded 2.5.2 (as I did with other packages also), it worked for 1 time, then I get same fail message, same as when I upgraded to other versions.
Why does my Arduino ESP not allow me to code?
Finally, be sure to reconnect the GPIO0 section to Ground (GND) when assigning code. (extra connect) Otherwise, the ESP will act as flash and will not allow you to code. Bheeshma is a new contributor to this site.
Is there a problem with esptool.py script?
Traceback (most recent call last): yes, there is a problem with the new esptool.py script responsible for uploading sketchs to arduino boards. (in my case esp12). if you downgrade the library for esp8266 under ver 2.6.0., probably it will work. try this case! we need to inform the dev guys (on github) to patch / change this script.
Why is espytool timed out waiting for packet header?
The espytool.py reports “timed out waiting for packet header”. I’m using the generic8266 board drivers. I’ve tried grounding and not grounding the RST pin on the Arduino. I’ve used ESP8266 modules from two different suppliers, though I expect they use the same source, as they look identical.
Can a laptop connect to an ESP8266 board?
Minor success, yesterday I detached everything from the laptop, booted, plugged in the serial connector and ESP8266-01S, and not only updated the firmware loaded a sketch as well. On 2 seperate 01S boards.
The blue light blinks on the ESP8266. It works fine in AT mode. Do the LEDs flash in same sequence when you power up with/without GPI0 pulled to ground? If they do the ESP is not going into flash mode and you get this message. It is then a case of determining why your ground link is not working.
