I recently purchased another LTE modem kit (I now have 3) and it came with the newer, better, Telit LE910C4 modem. The other two kits i have came with the Telit LE910C1. I followed the exact same steps i did with my other two devices. The GPS is working perfectly for the other two, but not this one.
Details:
AT+CGMR
MOF.660010
OK
AT$GPSP?
$GPSP: 1
OK
AT$GPSACP
$GPSACP: ,,,,,1,,,,,,
OK
I have followed the steps to configure the GPS as per both This Tutorial and with the slight tweak for QOS as outlined in This Thread
I have tried multiple GPS antennas. I currently have the device high and with a clear view of the sky. I have waited days to allow it to acquire signal. The other two devices acquired signal almost instantly.
It is important to note that while following the steps in your tutorial and in the telit manual, after the reset of the NVM history buffer, when i execute AT$GPSACP, I always get back ,1,. I never get a blank response.
The ironic thing is that this happens to be the device i’m going to install at a customers site. And it happens to be the one with the new modem version and problems. That’s how it goes it seems.
Any help is greatly appreciated.
