EC25 GPS auto initialize

I am using EC25 with embedded board using ubuntu.
When board start working EC25 doesnt response from ttyUSB1. But if I write

AT+QGPS=1

at ttyUSB3, I can get response(location,speed etc.) from ttyUSB1. How can I make this automatically when device power on? I'm trying with gtkterm.
I tried different thing but didnt make it.
I'm running python on board and I have crontab file for auto start my python code.
I would like to know a command line or settings for fixing my problem.

  • I already tried to AT+QGPSCFG=“autogps” and AT+QGPSCFG=“autogps”[,<autogps>] but it given error "gne error: 501(device user manuel)
  • I tried to AT+QGPSAUTOSTART=1 (I dont remember where I saw this command) but its given "error"

Problem Solved! First AT+QGPS=1 return OK then AT+QGPSCFG="autogps",1 return OK for checking the command; AT+QGPSCFG="autogps" return autogps, 1

Solution

  • Using a search engine with keywords "EC25 GPS" I found a support forum https://forums.quectel.com/t/ec25-do-not-get-gps-position-from-gnss-module-after-reboot/9353

    To make GPS automatically run after power on, please refer to command AT+QGPSCFG=“autogps” of the attached document.

    The page contains a download link to the manual.

    2.1.9. AT+QGPSCFG=“autogps”[,<autogps>] Enable/Disable GNSS to Run Automatically

    I guess you might have to use normal (typewriter) quotes instead of typographical quotes.

    Note that <autogps> is a placeholder which has to be replaced with 0 or 1 according to the manual. [ and ] mark optional parts. Correct command might be

    AT+QGPSCFG="autogps",1
AT+QGPSCFG="autogps",0
AT+QGPSCFG="autogps"
