GPS Neo8M Help
I'm trying to use an ESP32 (NodeMCU-32S) to connect to a GPS (Neo8M) to be able to read location data. The issue I have at the moment is I believe it isn't transmitting any data or even connecting. I may have messed up the wiring somehow, an issue with power or the Neo8M. I have the Neo8M connected to the esp32 at RX2 and TX2, connected properly to ground and the siderail of the breadboard to 3v3 power. It isn't showing anything or locking on to a satellite at all really. Any help?

The ESP Is fine, prints to serial monitor if i'm using a gyro
Also no lights on the Neo8M
Using RX2 and TX2 as an gipo can mess up the Esp32, try using other pins
Which ones should I use?

Hello! Please just correct the name. Its an M8 not 8M. As I know, this little guy works with a ceramic antenna. Do not power it without an antenna attached. Next, it doesn't care much about who is reading it, it just spits some sentences on its serial. So I would first plug a working antenna. Power it, and then grab any serial to usb adapter and plug it to the computer and watch what is being sent. If you have a handheld oscilloscope you may even see the signals, doesnt even need a computer to know if its working.
To me it is working, you just need to understand what he is telling you.
