Esp 01 does not connect using ESP core version 2.4 or higher and Blynk 0.5.4

Thank you so so much! :grinning::sunglasses:
Your settings worked like a charm and I learned a thing or two :slight_smile:

I had a couple of other ESP’s which worked with flash mode : DIO settings.
Then I got a couple that didnt. I googled the issue and tried the tips. Flash Mode : DOUT worked.
So I have been focussed on using DOUT. Never thought about using the QIO setting.
