I need some help.
I have an EC20F module, th revision is EC20CEFAGR06A04M4G.
I have a problem about Injecting gpsOneXTRA.
I send “AT+QGPSXTRADATA?” to AT Port and it always return "+QGPSXTRADATA: 0,“1980/01/05,19:00:00”
even though I’ve send “AT+QGPSXTRATIME=0,“2019/12/04,15:19:30”,1,1,5” with return OK.
Did I miss any steps?
Whether you have follow up the following steps to inject the data and time ? If not, please correct it and test again. If yes, please help to provide your whole test AT log, then i can help to check the root reason. Thanks!
Many thanks for your help!
I refer to this manual:Quectel_EC20_GNSS_AT_Commands_Manual_V1.1.pdf
My code is follow these steps:
All AT command is end with “\r\n”.
Query the gpsOneXTRA data is invalid?
Download XTRA file to PC from this URL http://xtra2.gpsonextra.net/xtra2.bin
and Save it on my embedded device (Linux 4.4.167).
Send XTRA file to EC20 module.
Wait for “CONNECT”
Send XTRA file data
1K each time and sleep 300 milliseconds.
The invalid time is after 24 hours.
My log as follow:
I got failed when try this:
