A-GPS XTRA file size to big for PLS8 | Telit Cinterion IoT Developer Community

May 13, 2020 - 12:55am, 3775 views

Hello,

We manufacture a tracking device using the PLS8 modem and A-GPS for improved GPS performance.  It seems there has been a change to A-GPS file size on the  http://xtrapath4.izatcloud.net/xtra2.bin  server.  The file length is now around 61832 bytes but the maximum allowed A-GPS file length for the PLS8 is 61440 bytes, resulting in an error.  Strangely, in rare cases the file length is less than 61440 bytes and then A-GPS startup does work. Why the file size should change when downloading the same file from the same server within moments of the previous download seems very odd.   Could you please let me know if you have any information on this issue and any possible solutions?

Thank you,

Ed Haslam
