+==== Base ====
 The LG290P is put into base station mode with a few commands and reboots. The unit can self-survey or known ECEF coordinates can be provided.
@@ Line 29: / Line 29: @@
 There are a number of different ways to configure the LG290P for base station mode, this is just one I have found to work well for me. Read the base station application note for more detailed information and options.
-=== Rover ===
+==== Rover ====
 The default configuration of the LG290P is to operate in rover mode. The easiest way to enter this mode is to reset the unit to defaults.

-The resulting sentences are sent at 10Hz and are quite dense, a baud rate of 460800 is recommended. If 10Hz data is not required (or the bandwidth is too great) the sentences can be slowed down using the ''$PQTMCFGMSGRATE'' command. GSA((Satellites in View)) and GSV((DOP and Satellites in Fix)) are by far the longest and consume the most bandwidth. If you want a 10Hz location stream, but don't need GSA/GSV at that rate, they can be individually slowed to 1Hz:
+The resulting sentences are sent at 10Hz and are quite dense, a baud rate of 460800 is recommended by Quectel. If 10Hz data is not required (or the bandwidth needed is too great) the fix rate can be slowed to once per second, for example, with ''$PQTMCFGFIXRATE,W,1000*59'' - the number is milliseconds-per-fix.

+==== Baud Rate ====
+It may be necessary to adjust the baud rate for one of the three UART interfaces. This is done with the ''$PQTMCFTUART'' command.
