EHS8 GPS antenna power always on ? | Telit Cinterion IoT Developer Community

July 1, 2017 - 12:10pm, 2856 views

To my surprise, the active GPS antenna I used for the first experiments with the EHS8 GPS worked right out of the box, even though the necessary settings were not made. That is, SCFG "GPIO/mode/GPSANT" was not set to "std" and SGSPC "Mode/Antenna" was 0 (passive). I even tried changing SGPSC "Power/Antenna" to "off", but whatever I do, there is always 3.3 V on the antenna. Restarting the ME does not change this. The GPS active antenna power seems to be always on.

So I am surprised and slightly confused... What could be the cause of this?

If we leave it at this, conclude that power will always be there and not bother setting it up properly, what will be the risc of future devices not showing this behavior? 

Any comments would be welcome!, TIA!
