EHS8. Use of GPS and AT Command only with ASC0 at the same time without Multiplexor

Tutorial, November 3, 2016 - 9:05am, 1500 views

Hi,

yes this is possible - define

 

at^sgpsc="Nmea/Interface","local"

 

and start GPS by :

 

at^sgpsc="Engine"," 3"

 

NMEA frames goes to port when you start GPS.

 

This is not blocking mode so this means that NMEA frames come but in between you can do AT commands - for example stop GPS by :

 

AT^SGPSC="Engine","0"

 

You can also use buffered mode by:

 

AT^SGPSC="Nmea/Output","buffered"

 

After ~ 1 minute you got URC:

 

^SGPSCE: 0,0,31488

 

later

 

^SGPSCE: 0,1,39360

 

which mean that buffer is full - you have to read NMEA by:

 

AT^SGPSC="Nmea/Output","on"

 

And later change again to

 

AT^SGPSC="Nmea/Output","buffered"

 

or to

 

AT^SGPSC="Nmea/Output","off"

 

Also there is possibility to make NMEA output to file  - all options are described in ATC.

thnak you to Lukasz for the description and tests.

ALopez
