I wanted to send AGPS data to my UBLOX CAM-M8, so get a faster fix as the chip doesnt have a eeprom to save the data and not even a battery backup.
I understood that every chip needs to download a map of where all the satellites are in the space and then based on that information, the chip can triangulate the position.
The great information is that UBLOX provides a free access to the AGPS servies which you will need to provide a close location ( latitude and longitude) and then a file is generated.
To send this file, you will need to parse the data and send the message via Serial and because I couldnt find anywhere a sample code, I tried to code something which actually worked.
The real sending would be too check the ack message, but this worked fine for me.
