EM-408 problem

GPS/GNSS Development Boards
1

I have bought GPS EM-408 and GPS-EVALUATION board which support EM-408, first time the GPS receiver was working , after that I sent this query command ($PSRF103,00,00,00,0121) by SiRFDemo to stop GGA, then I sent ($PSRF103,00,01,00,0125) to get GGA once, but I did not get any thing .

Please help me.

Note:

I tried to switch on all NMEA sentences and reset the receiver but it did not solve the problem.

Hi,

Did you ever resolve this problem? I have been using several EM-408 modules for the past few months with no issues. The SiRFDemo software can be a bit non-intuitive/quirky, so I’d bet that’s your problem.

What is your current status?
