I have been working on an IoT project with NodeMCU.

What I need is to wake it up every 5 minutes.

I read some articles about the deep sleep mode of NodeMCU and found that I need to wire the RST pin to the GPIO16(D0).

But if I wire both of them, NodeMCU does not boot and the LED blinks very quickly.
If I remove the wire, it works normally.

Should I wire them through a resistor?

Thanks.

1. Resistor 10k from RST to Vcc
2. Resistor 330R from RST to GPIO16
Values of resistors ​​are not critical.

Hi, thanks for your reply.
I just tried, and unfortunately it does not boot...
