USB-WIFIGPS OLED Version-Sync time with NTP server via WIFI

 

[For reference only]

 

In this guide you’ll learn how to config and use the WiFiGPS. 

 

Plug WiFiGPS into USB power socket,if this is the your first time running the WiFiGPS, you need to do some configuration.

 

You can use a device that supports WIFI connection, like your computer, your laptop ,android cellphone etc.,Then scan for WIFI networks and you should see WIFIGPS-APxxxxx listed.

 

Connect to this WIFIGPS-APxxxxx WIFI hotspot, then using your web browser go to 192.168.4.1 and you should get the WifiGPSManger main page.(!!!If can not connect to 192.168.4.1,Would please check if you have set VPN or PROXY etc. in your web browser,if so,remove or turn those stuffs off!!!)

 

 

For the first time setup,recommend you enter the [Setup] part first,when click the [Setup] button,will list WIFIGPS NTP part parameters for you to set.

 

The [NTP SERVER NAME] part,you can set or select your own NTP server or select via the list(Please delete the server name first then click the right arrow,will show all predefined servers in the lists,recommend using pool.ntp.org).

 

Select your [Time Zone] via the second list. The first 7 lists are currently with auto Daylight support (in testing) shown blow.

AustraliaEst-Sydney(GMT+10:Daylight);

CentralEurope-Paris(GMT+01:Daylight);

UK-London,Belfast(GMT+00:Daylight);

US Eastern-NewYork(GMT-05:Daylight)";

US Central-Chicago(GMT-06:Daylight)";

US Mountain-Denver(GMT-07:Daylight)";

US Pacific-LA(GMT-08:Daylight)";

 

In the [User Define Time Offset(ms)] part,you can set time offset in like +500 for current time+0.5sec,or like -500 for current time -0.5sec to set the time offset you want.If no need this function,set it to 0.

 

The last [User Define Update interval(sec)] means how many time interval will WIFIGPS sync time via NTP server,like if set to 3600, the WIFIGPS will sync time online via every 1 hour.

(!!!Recommend set in no less than 60 sec.  In some of version,if set to 0,the WIFIGPS will enter power save mode,in this mode,the WIFIGPS will do loop,like try to sync time online,then output time data for ~20 sec,then back to sleep for ~30 min,then wake up again!!!).

 

The [Show WIFI Advanced Options] if be selected,you can set like "Static IP address"... in [Configure WIFI] part.

 

When all set,click the [SAVE] button blow.

 

 

 

Then back to main page,enter [Configure WiFi] part,enter your WiFi SSID and Password in it,then click [SAVE] button blow.

usually after finished setting the WiFi SSID and Password,the WiFiGPS will reboot,if not,please re-plug the USB power to force it to reboot.

 

If all setting is correct,the WiFiGPS will try to connect to your WiFi hotspot then sync via online NTP server to get the current time,then output the time data via USB D+ pin in 5V 9600Bps UART output.

 

Sample Output Format:

 

$GPRMC,000000.000,N,0000.0000,N,00000.0000,E,0.0,0.0,000000,0.0,E,S*18

$GPRMC,000000.000,A,0000.0000,N,00000.0000,E,0.0,0.0,000000,0.0,E,S*XX

 

Output speed in 0.5sec per one $GPRMC string.

 

 

 

For the STD. version of WiFiGPS,it contains an led on PCB,when in configure mode or can not connect online or can not get NTP time data,the LED will be turned ON;

 

When everything is fine,it can SYNC time online and output time data,the LED will be turned OFF.

 

If you are using OLED version of WiFiGPS,more info will be displayed on the OLED screen on PCB.(If in Power Save mode,the OLED brightness will be turned OFF or in the lowest brightness for saving power).

  

Reconfigure or reset setting

 

If you have set the configuration already and you want to reset it,it may have a button on PCB for some version.When the WiFiGPS works in normal working mode(LED OFF,Time Data output in normal) then keep this button be clicked for about 4 sec,will reset all the configuration data.

 

If it contains no button or you do not wanna click the button,you can turn off your WiFi or move WiFiGPS to a far location where it can not receive the pre-defined WiFi signal,then plug the WiFiGPS in the USB power,wait for a while...,when WiFiGPS can not find pre-defined WiFi hotspot,it will enter the setup mode by itself.
