hl8548-G EXT_LNA_GPS_EN

I used this pin to turn on/off a switch supplying the bias to the active antenna.Just like that is write in the Design GuidelinesGNSS: Active Antenna Integration.
I used AT+KSLEEP=1 to make the module enter sleep mood.when I Waked the module up and I believe it waked up,but EXT_LNA_GPS_EN sometimes do not ‘H’,always ‘L’.
Because AT+GPSCONF=1,1.
Internal LNA set to Low Gain and GPS receiver EXT_LNA_GPS_EN output signal is automatically driven.
What it means? automatically driven.
When does this signal become ‘L’?

Hello,
Issues seems to unclear from the above description , can you please provide more technical info which could help to understand the issue.

Thanks & Regards,

Hello,
Thanks! I’m not good at English and try to explain it simply.
I use the command :AT+GPSCONF=1,1.
It means that Internal LNA set to Low Gain and GPS receiver LNA_EN output signal is automatically driven.
What it means? automatically driven.
When does this signal become ‘active’?

I think that GPS receiver LNA_EN output signal is EXT_LNA_GPS_EN.Am I right?
