Recently I have picked up few ESP01s boards as an addition to my IoT Platform arsenal (Arduino is kinda nailed 101% at the moment). However regardless what I did (and I did read quite a few tutorials) that thing did not want to output any meaningful serial information nor it was going to connect to a wifi network... 2 days later I finally managed to get it to work! Maybe it is just me but I could not find one set of settings anywhere that would just work, so here it is:
And yes, there are other issues you can encounter while getting started with the ESP01s for the first time but this was my game stopper. Also keep in mind that when flashing with different firmware it could potentially work on a different serial speed for the serial monitor like 9600. Enjoy!
