I just realized I was using the flasher version 3.9.5 from the beginning.....

I found version 2.3 and guess what, all my modules are now updated successfully and I can check this via AT commands...

Okay, thanks to amgen, I finally successfully flashed my module.

But, still nothing works and sending AT+GMR will return...nothing at all.

Maybe my three modules are just defect...

I think...

Thanks a lot Amgen, I'll give it a try tonight.

Until then, just a question about your addresses: are these really correct?

...or does it just doesn't make any change if they have one...

BTW, ESPRESSIF seem to have a firmware, the ESP-WROOM-02 Series that should fit the ESP8266 according.

Amgen,

Would you please share the firmware you've installed?

I tried so many that didn't work....

There's quite a jungle of firmwares available for these ESP modules.

Which one should I use? Which one will allow me to "simply" send and receive a few bytes back an forth between a PC and a PIC?...

...can't edit my previous post.... so here is the picture ment to appear:

Don't know yet.

I think I'm going to use some kind of mobile Terminal app or, if possible, a web browser or even make one by myself with MIT App Inventor which I'm already on my way but using...

Amgen, what exactly is a "bridge"? Is it what I actually want to achieve = send (small amount of) data, both ways, between a PC and a PIC over Wifi?

...as you suggested, I tried with mode 3 and:

Thank you very much Henrik :wink:

No. I'll give it a try when I'm back from office.

Unfortunately, no.

Still searching....

Okay, for now, I'm trying to get started with this piece of info https://www.instructables.com/Getting-Started-With-the-ESP8266-ESP-01/

Hi there,

I'd like to transfer a config ".TXT" file (it's a bunch of 100 bytes or so) from my PC to a PIC over wifi.

So first things first: power it up and find some AP to connect to.

BTW,...
