Hi there.
Hope evryone is well.
I need to know if I can send data from a GPS module to a server, via another GPS antenna?
So can Arduino use one GPS antenna to recieve data, and use another to send it?
Thx

No, not as I can dream of. The GPS chips are receivers, receinig data from the sattelites.
ok, I have an antenna that connect as a modem and send short msg to satelite that gets recieved on the other end as an email.
But I want to send GPS data, so I have a Rx and Tx connection on my Arduino board, now do I connect both on the same connector like I2C and can Arduino see if it is an incomming or outgoing signal, or can I tell it to use another pin for sending.
So to change the question a bit.
Can other pins be used for serial coms or only the ones marked as Rx and Tx.
Sorry for not being clear on the question, but thanks for the reply.

Ok, You already have a transmitter, and antenna, that can communicate with sattelites. Just make the data being whatever information You like. Make Your Arduino create data for Your sattelite transmitter. Rx, Tx is one opportunity and I2C is another. Maybe Software Serial can send data, not onle receive.
Ok. I get that. What my newby problem is, is that both use Tx an Rx if I plug in one I get the data. I then need to unplug it and plug in the "modem" to send the data. Can I do this without changing cables.
I know that it may sound like a stupid problem, but if I can program 2 other pins to be Tx2 and Rx2 and tell arduino to use them to send, my problem is solved, So how do I tell the uno board that it needs another serial port?

During the time of developing the software You need to use the USB connection. That USB uses Tx,Rx…. Plugging and unplugging is a time consuming exercise.
As I wrote, investigate "Software Serial". It uses almost any I/O pin. Here's a link to it: Libraries - Arduino Reference. Use that as the channel from Your Arduino to Your sattelite transmitter.
awesome.
Thx
I think this will put me on the track again.
Eagle out..
Good luck! Wellcome back, if You need.
Giving me a pluspoint? (Karma).
You can send small amounts of data through satellites, from just about anywhere in the world, using the Arduino compatible RockBlock modem. Software serial works fine for that.
Whow!
