To get better GNSS performance on Bolero40, we would recommend
|
|
|
|
to set it with:
|
|
|
|
|
|
|
|
a)
|
|
|
|
$PFAL,CNF.Set,DEVICE.GPS.GNSS=GPS,GALILEO,GLONASS //For Europe
|
|
|
|
or
|
|
|
|
$PFAL,CNF.Set,DEVICE.GPS.GNSS=GPS,BEIDOU,GLONASS //For Asia
|
|
|
|
|
|
|
|
|
|
|
|
b)
|
|
|
|
You also can use this function:
|
|
|
|
$PFAL,CNF.Set,TCP.CLIENT.SENDMODE=2,1000
|
|
|
|
|
|
|
|
which means it collects the data up to 1000 bytes (the buffer level is up to 1000000 bytes) and when this storage
|
|
|
|
gets full, it sends the collected TCP's.
|
|
|
|
|
|
|
|
Also you can force the device to push the collected TCP with
|
|
|
|
|
|
|
|
PFAL,TCP.Client.FlushSendBuffer
|
|
|
|
Suppose the car has been parked but the sendmode user storage size is
|
|
|
|
not full, you would get the messages later.
|
|
|
|
|
|
|
|
Example:
|
|
|
|
$PFAL,CNF.Set,TCP.CLIENT.SENDMODE=2,1000
|
|
|
|
$PFAL,CNF.Set,AL40=IO.e8=fedge:GPS.Nav.SaveLastValid&TCP.Client.FlushSendBuffer
|
|
|
|
|
|
|
|
c)
|
|
|
|
We also recommend to use the internal battery to keep the
|
|
|
|
ephemris/almanac data available and to prevent any GNSS cold start at
|
|
|
|
every device restart (in case the external power drops or not stable).
|
|
|
|
|
|
|
|
$PFAL,CNF.Set,DEVICE.BAT.CHARGEMODE=eco
|
|
|
|
|
|
|
|
$PFAL,CNF.Set,DEVICE.BAT.MODE=auto |
