I have made a PCB using M20048 as standalone. I tried to use Arduino to get GPS coordinate. Connect TX and RX M20048 to RX and TX of Arduino. I am using TinyGps++ library. I tried also to connect M20048 TX,RX to USB to TTL and there is no response from the module. I am not using any antenna because i want to use the integrated antenna which comes with the module. I checked the power and it's 3.3V, I also checked Tx,Rx Power of M20048 and it have voltage, the last thing I did is to check if there is any short circuit but there is no. Hope to get some help
