I run my Arduino Nano IOT 33 after double clicking the reset button and it works fine. However, as soon as I upload code to it, I cannot open the serial, see the port, or connect my blynk app to it.
Sorry for not explaining it well the first time. As for the code I do not have specific code that is causing an error. I even uploaded a hello world sketch and it did not work.
my pinout is the following
3.3V -> V(external analog sensor) 3.3V -> V(external analog sensor) A0 -> pinIn A1 -> pinIn Gnd - gnd Gnd - gnd
