Hello everyone, Does anyone know how to use USB to TLL for esp8266 New NodeMcu V3
USB to tll device: CH340 Module USB To TTL CH340G
The code am uploading is:
void setup() {
// put your setup code here, to run once:
}
void loop() {
// put your main code here, to run repeatedly:
}
I know how to connect the USB TO TLL to the esp8266,
My schematics:
Vin ---------------> 5 volts
Gnd ---------------> Gnd
Tx ---------------> Rx
Rx ---------------> Tx
but it gets stuck at:
connecting. here is what it says while uploading:

This board is working without the USB TO TLL. so it is no way the board is the problem. I guess I don't know how to use a USB TO TLL correctly.
