Then add to this post. People will need to see your code, pictures of how things are connected, and you need to describe your problem and ask a defined question.
Then you are much more likely to receive help from this forum.

Take a look at Installing ESP8266 in Arduino IDE (Windows, Mac OS X, Linux) | Random Nerd Tutorials

Hi Dozie,

Thank you but I still get the same error. I have attached a screen shot of the ports that I find when selecting the port. I’m using a Macbook Air.

Is this correct?

Kind regards,

Gavin

@kagtech01 The steps ( Installing ESP8266 in Arduino IDE (Windows, Mac OS X, Linux) | Random Nerd Tutorials )sent to you is what you need to solve the issue. Check:

  1. that you are not using a poor quality USB cable (use data USB cable) and that you are not using a USB bub. Avoid also USB 3.0.
  2. try it in another computer with Windows OS.

Hi Dozie,

Tried it on a windows machine with following error:

What am I doing wrong? It seems so simple but not working.

Can you please provide pictures of your board and connection?

Hi,

Note pictures attached. Switch connecting IO1 with ground to trigger esp 01 into programming state..

Cheers,

Gavin

Remove anything wired to the board and use the steps sent earlier. You are probably using a bad USB cable, instead use a good quality high speed data cable. See:

Why is your board not seated in the adapter correctly? It's offset by one set of pins.

Quick inert for phot. Unit correctly seated when error was logged.

Hmmmmmmm
You miswired and powered the board. I'm not sure if you killed it or not. A more talented user might be able to tell you.
