- Fri Aug 05, 2016 12:07 am #52167 Hello guys..
Recently i bought a Neo 6m GPS module for a my University project.I'm new to this module.I was thinking about connecting it to my Esp 12.but i am unable to get gps module to work.(I'm sorry guys i know it is bit off from the subject but i really need some help..Please Don't get angry ok.)

So far here is what i did..
first I downloaded u center and installed..

1.I bought my laptop outside of my house and connected Gps module to the USB/TTL module.
2.I went to device manager and got right com port.
3.then opened the software and got correct com port and baudrate 9600.(I downloaded a Youtube video and followed its steps https://www.youtube.com/watch?v=TwhCX0c8Xe0)
4.Now i think there should be some data in the packet console.but i got nothing in the software.

Onething i have noticed is when i check VCC,Rx,Tx and GND with multmeter,they are shorting.Its like they are all connected together.is that normal ? Is there any solution for this ? what i am doing wrong ?

If any one of you guys have experience with module can you help me ? So far i searched in google every way i can but i got nothing.I really don't know what to do now.little help will be really grateful.Thanks..

also, iirc, that gps board is better to power from a 5v supply

Hey villTech..I also tried with separate 5v power supply ( with a 5V linear regulator ) but still same problem.

First the GPS and the receiving device need a common ground. Next RX goes to TX and TX to RX. Voltages matter the esp8266 should be exposed to more than 3.3.v. This is TTL serial so it is current driven you probably can get by without 100 ohm series resistors with the esp8266 bu they are a good idea since the esp8266 can only sink so much current.
It is very hard to diagnose remotely. It does work and you with a meter should be able to diagnose the electrical interface.
Next there is the software...the GPS interface is asynchronous so you need code to buffer any sentence whenever the GPS squawks.
