PLS8_US_R4 GPS, AT^SBNW Command | Telit Cinterion IoT Developer Community

So far I've been unable to successfully download the xtra2.bin from my Raspberry Pi to the PLS8 FFS.
Here is the firmware version:
I entered the following command sequence on the MODEM interface:
AT+CCLK="21/07/04,14:53:00" ( This was set correctly, UTC)
AGPS READY: RESET GPS ENGINE AND DELETE XTRA FILE...
AGPS: END OK
AT^SBNW="agps",60698 (size has been verified numerous *****)
AGPS READY: SEND FILE ...
At this point on the APP interface, I used this command to download the file:
cat xtra2.bin >> ttyUSB0
However, the download failed with the following error
AGPS: SERVICE TIMEOUT ERROR
AGPS: UNDEFINED ERROR
+CME ERROR: operation failed
I need some clarifications and any help would be greatly appreciated.
 In the datasheet there are 3 download links. The files are different sizes
depending on the link. Which one do I use?
 How should I download the file from the host PC to the PLS8? Is there a utility?
