Dear Sir,
It already introduce how to import the file into the module in the document, you can use AT+QFUPL. Thanks!
About the GPS accuracy, it mainly depends on your test environment, and the searched satellite SNR. The xtra data just can speed up the positioning. Thanks!
hi,
can u send Quectel_QCOM_User_Guide ?
so it will helpful to me
hi,
the xtra2.bin binary file (for gpsoneXTRA function) is loaded to EC25 module through QCOM tool.
attached screenshot(in image at last added file).
After that i am running AT COMMANDS through ttyUSB2 port , but i am getting error
- AT+QGPSXTRA=1
OK
after (AT+QGPSXTRA=1) i am restarting ec-25 module and running following command
- AT+QGPSXTRADATA?
+QGPSXTRADATA: 0,“1980/01/05,19:00:00”
OK
3) AT+QFUPL="RAM:xtra2.bin",59748,60
CONNECT
+QFUPL: 0,0
+CME ERROR: 421
4) AT+QGPSXTRATIME=0,“2015/01/03,15:30:30”,1,1,5
+CME ERROR: 508
Dear Sir,
It is better to provide your whole test log.
From the log you provided, it is failed when upload the file to module. Before you upload the file, it is better to check whether there already have such file inside the module. And you also have set the wrong parameters in the command AT+QGPSXTRATIME, please double check it. Thanks!
The following AT sequence just for your reference. Thanks!
hi, how to do cold start , warm start , hot start with ec25-e module ?
Dear Nikhilvp29,
About the cold start, warm start, and hot start, it is depends on whether the downloaded XTRA data still valid, Normally, if the time interval between two start times less than two hours, it should be hot start, if it more than two hours but less than 6 hours, it maybe warm start, and if it more than 6 hours, it will be cold start. Of course, if the devices move far away from the first position, even the time interval less than two hours, it also be cold start. Thanks!
hi ,
how we can send gps location via sms ?
module - EC25E
Dear Nikhilvp29,
If you want to send GPS location via SMS, maybe you can try to set CSCS as “8859-1” or other mode that you think can sent it. But before you set it, you need to check whether the module support such mode with command AT+CSCS=?. Thanks！
hi,

they given these modes,

how it will take data from gps and sent through sms ? i am confused about it .
Dear Nikhilvp29,
If you want to send GPS location via SMS, you need to get the location information firstly, then write the location data into SMS, and send the SMS to remote device. All you need to completed by your MCU, Thanks!
thanks for responce.

hi,
how to do firmware upgrade in EC20 ?
AT+QFOTADL="/cache/ufs/update-v13-to-v12.zip" where we can get these .zip file ?

Thanks for your inquiry in Quectel forum.
You can upgrade the module firmware via FOTA or Qflash tool. If you want to use FOTA, you may need to apply for the delta firmware package, you need to contact our local FAE to apply for it, please email to support@quectel.com to get the contacts of our local FAE in your country. Thanks!
