Dear Sera,
Thanks for your inquiry in Quectel forum.
For your issue, i think it is the xtra2 file have not upload successful.
You can try to check whether the RAM free space is enough for this file.
And it is no need to reboot module after you send AT+QGPSXTRA=1 command. Please retry it. Thanks!

Dear Kyson

How to check RAM free space?

Please use the following command. Thanks!

Thank you for reply.

[2020-03-25 17:33:18:281_S:] AT+QFLDS=“RAM”
[2020-03-25 17:33:18:284_R:] AT+QFLDS=“RAM”
[2020-03-25 17:33:18:285_R:] +QFLDS: 2606080,2616320

[2020-03-25 17:33:18:285_R:] OK

I think enough RAM free size.

Dear Sera,
Yes, the RAM free size is enough. So for your issue, it is better do not reboot the module after you send AT+QGPSXTRA=1 command. Thanks!
You can check the following AT sequence. Thanks!

I didn’t reboot. but occur same error.

Dear Sera,
Please double check when the it return CONNECT, whether you will click to send file, and whether you have delete the old file existed in module RAM. Please use AT+QFLST=“RAM:*” to check whether it already exist the xtra2 file, if yes, please delete it with AT+QFDEL=“RAM:” , then upload it again. Thanks!

Dear Kyson

success upload file! thank you
I have a question.
why use AT+QGPSXTRATIME=0,“2020/03/26,15:30:30”,1,1,5
Is this command necessary?
What happens if I input the wrong time?

Dear Sera,
Yes, it is need to inject the time, and must be correct time. As you know that this time is for gpsoneXTRA, which is helpful for accelerate the positioning. So please pay attention to it. Thanks!

Hi there,

Can anyone help me with the “send xtra2.bin” QCOM? I downloaded the xtra2.bin to home/pi/ . Is there a specific location that I need to keep the file if I am launching the minicom from the same location?

Thanks in advance.

Saman

Dear Saman,
You can check the following user guide of QCOM tool. Thanks!
