I have been evaluating the EM7455 module using the AirPrime EM series PCIe Development kit in Ubuntu 16.04.
When I connect the device to my Ubuntu system I see three com port named ttyUSB0 , ttyUSB1, ttyUSB2.
I was able to connect to the mobile broadband, also able to give AT commands in ttyUSB2 and get responses.
But i’m unable to get the GPS data from any of the ports ttyUSBx.
The AT commands I used are
SWI9X30C_02.24.05.06 r7040 CARMD-EV-FRMWR2 2017/05/19 06:23:09
Current time: 2018 08 03 4 11:03:25
2018 08 03 4 11:03:25 Last Fix Status = NONE
2018 08 03 4 11:03:13 Fix Session Status = ACTIVE
No TTFF available
I have also tested these sequence in open sky environment, but the results are the same.
So can anyone suggest me the correct procedure to get the GPS data from the module?
