Probably everyone on here has done this in the past and considers it too easy.
i have been studying C++ code now for the last 4 days, and still can't get answers to my problem.
i have modified tonnes of code, including the examples codes. still can't get anything to happen.
what i am trying to do is read the NMEA data from a GPS module (which i know ouputs it automatically at 9600 Baud)
store it in a buffer and then add a identifier code to it and then after a small delay broadcast that data using a 433mhz radio link.
the idea being that you could use a few gps modules together to track different items via radio link back to a PC using the ID number to identify which position belongs to which item..
i've tried to modify all the GPS examples, but all of them seem to be decoding the NMEA strings and using parts of the data.
i need it to be left untouched, but add a line before with an ID code.
does anyone have any ideas on the code required to do this?,
any help would be greatly appreciated!
Pretty ambitious project for someone who has been programming for 4 days.
Split the project into parts. Start with getting data from the GPS. Do not consider moving on until that works.
When it does, then you can work on storing that data. When you can recognize when a sentence starts and ends, and can store a whole sentence, the rest of the project should be easy.

Beyond lat and lon, what else do you need to track these objects? The heading and number of satellites don't seem all that useful. But, if they are, broadcast them, too.
The first things anybody will ask are questions like what Arduino are you using, what GPS module & shield, what 433Mhz radio module. preferably with links to where you got them from or the manufactures web site & finally upload the code you have tried (putting this code in code tags). There are several makes and models of GPS & Radio modules and probably more versions of libraries to interface them to the arduino.
I know that this is an old post, but it is the closest to what I am trying to do and am stuck as well. In short I want to use an UNO to send GPS data(ultimate GPSv3) to another UNO using either a RFM12bsp or RFM69 at which point I would then send it to a cloud based site like ubidots.com. Currently I am having issues even getting just the TX/RX working. I am wondering if I got bad boards. Currently looking for simple code to test them, but would like to see any other code that sends GPS or DHT22 data.
