I connected the pins accordingly:
GPS...Wemos
Tx -> Rx
Rx -> Tx
5V -> 3V3
GND -> GND
The GPS module can be powered with 3.3 to 5V and the logic level on the Tx/Rx pins is 3.3V.
I configured the baud rate of the module to be 115200, and wrote a very basic sketch:
Serial.begin(115200); in the setup function
...
if (Serial.available() > 0) {...} in the loop function.
The condition above is never met. It appears no data is sent using the serial interface. Do you guys know what is wrong here ?
