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, this is the very common module I have, the ESP-01S:

My first action is to get connected to the wifi, but I always get an error message when trying to list the networks (I can see at least five APs on my mobile):

Has this "ERROR" something to do with the firmware? There are so many versions out there (mine looks already old...2015...) that I don't know where to look at for a start....
