Projects Programming
1

Hey guys I Am Using An Esp8266 To Send Messages In Telegram.I Have provided the ssid and pass and the bot token and the recipient's chat Id.but the main problem here is Uploading The Code to Esp8266.It Says An Error And I Couldn't Solve It . Please solve my problem.I Have searched everywhere nothing seems to help.

The error is : a fatal estpool.py error occured: failed to connect to esp8266: timed out waiting for packet header

It would be very very very helpful if u could send me the solution

This is the code I used and I got it from a website.the website link also there at the start of the code.

The issue is not in the code (it compiled) but in the way you have connected the ESP or which USB port you have selected.
What kind of ESP8266 do you have and how have you connected it ?

Depending on the ESP8266 board you may need to hold down a boot/flash button while you try to upload the code. Please link to the board you are using.
