Toms comment made me test my GSM antenna, lo and behold, it works:<br>

My GPS antenna is an active one for V2, it seems the current module
does not support active antennas.<br>
<br>
Actice GPS antennas are the standard choice over here. If the
SIM5360 can do without, that will eliminate another energy drain, so
is good. Users will need to know they'll need another antenna.<br>

I tried with mine. I’m getting the same. But GPGSV is showing 16
satellites… My testing setup is far from ideal, however; with an
extension cable and 40’ of GPS antenna stretched across my bedroom
to the balcony outside.

<div class="">It was working on the original prototype I tested,
so not sure what has changed.</div>

<div class="">Quickest is to ask the China supplier to check. I’ve
done that, and will let you know the result.</div>

<div text="#000000" bgcolor="#FFFFFF" class=""> I'm
currently working on the NMEA module. The MUX channel is
working, but I don't get a GPS fix.<br class="">
<br class="">
I've tried all GPS commands and now suspect my SIMCOM
module having a hardware issue.<br class="">
<br class="">
I'm doing this:<br class="">
<br class="">
<tt class="">OVMS > level debug</tt><tt class=""><br
class="">
</tt><tt class="">OVMS > power simcom on</tt><br
class="">
<br class="">
…wait for the MUX to be ready, then issue…<br class="">
<br class="">
<tt class="">OVMS > simcom muxtx 4 AT+CGPSNMEA=1</tt><tt
class=""><br class="">
</tt><tt class="">OVMS > simcom muxtx 4 AT+CGPS=1,1</tt><br
class="">
<br class="">
…now the SIMCOM begins sending NMEA $GPGGA lines once
per second looking like this:<br class="">
<br class="">
<tt class="">D (2937174) SIMCOM rx: f9 05 ff 35 24 47 50
47 47 41 2c 2c 2c 2c 2c 2c ...5<b class="">$GPGGA,,,,,,</b></tt><tt

2c 2c 2c 2c 2a 36 36 0d 0a 60 f9 <b class="">0,,,,,,,,*66</b>..`.</tt><br
class="">
<br class="">
Normally the modem should get a GPS fix within about 1-2
minutes and begin filling data in the $GPGGA record.<br
class="">
<br class="">
But my modem won't, it just keeps sending empty fields.<br
class="">
<br class="">
Can someone please try this with his/her module?<br
class="">
<br class="">
To disable the GPS receiver, issue:<br class="">
<br class="">
<tt class="">OVMS > simcom muxtx 4 AT+CGPS=0</tt><br

<br class="">
Thanks & regards,<br class="">
