So the rest of this topic was about a problem with an ESP-01 as a Wi-Fi modem for a an Arduino and you’ve said that you are
but in fact you’re using different hardware.
You say that you’ve done
I’d doubt very much if any of that has helped. If you’ve installed anything other than the correct AT firmware for your board (which will be different to the AT firmware for an ESP-01) then you’ll not get this working.
There’s a thread about someone else who has truied thys, and finally managed to get it to work, just here:
I’m locking this thread, as your issue is unrelated. If you need further assistance the please start a new thread with full details about your hardware, firmware, code, results etc but bear in mind that this isn’t really a Blynk issue until you get your Arduino talking to your NodeMCU.
Pete.
