Hi All, Does anyone know the details of how, most reliably and most quickly, to get a location fix from the GPS module after it has been powered up and after it has come out of sleep mode? I have written my own code using the OVMS hardware. To save power, it turns off the GPS power (AT+CGPSPWR=0) and puts the module to sleep (AT+CSCLK=2) while the vehicle is parked (i.e. no CAN bus activity). Once there is CAN activity again, it comes out of sleep mode (AT+CSCLK=0) and turns on the GPS (AT+CGSPPWR=1). Immediately after turning on the GPS power, I also issue one of the GPS reset commands (AT+CGPSRS=0 or AT+CGPSRST=1). The module documentation if vague about when to use the 0 reset or the 1 reset. I know that the GPS module itself isn't made to function while the module is asleep even though the commands may not give an error. I've read that it takes up to 15 minutes to get a fix on most GPS devices. In practice, sometimes I get a fix within a minute every time I start up, and other times I don't get a fix even after hours of trying with either reset option. Any information will be greatly appreciated. Thanks, Arthur
