ESP8266-01 sketch runs with UART bot not without
Posted: Thu Apr 26, 2018 1:58 pmHi,
I've a small problem: If I let run my sketch (I use the Arduino dev-environment) with an UART actively connected then the sketch runs perfectly. But if I let run the sketch without UART connected then it doesn't work. The flashing process isn't the problem, it works.
I have no idea what the problem can principally come from; an initializing problem or an electronically problem e.g. wrong resistors
The ESP8266-01 acts as a controller for a telephone dial and trigger an http event with the number was called.
I've tested it in two different variants with both the same broblem:
- use RX as switch (the pin0+2 as output)
- use the pin0+2 in combination as switch (pin0 set high/low on pin2)
Any idea?
