I recently purchased the GPS logger shield, as well as the EM-406a GPS unit. In the process of setting it up, I accidentally put the GPS unit into digital mode. With some research, I learned I could 1) wait 3 days for the unit to reset or 2) send a binary string to the unit, instructing it to switch to NMEA mode.
I've waited my 3 days and will revisit it shortly, but can anyone explain how to send that binary string? I am using this for a near-space balloon project and I want it to be bullet-proof. I'd like to send that string in the setup() function, to ensure it's always in NMEA mode.
Thanks!

Re: GPS Shield
The command is the Set Serial Port command - just over half-way down in this document: http://www.scribd.com/doc/14806180/EM406A-User-Manual

Re: GPS Shield
Right, I found that in the documentation (my bad - I should have been more clear). How do I send the command? Do I just write it to the serial port as-is, like this:
It's that simple?
Code: Select all
