BOLERO40_improvement_of_the_GNSS_performance.md

+Recommendations
+
+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**
