 Once compiled, firmware can be uploaded directly to a unit when the RTK unit is on and the correct COM port is selected under the Arduino IDE Tools->Port menu.
 
-Note: The COMPILE_WIFI and COMPILE_BT defines at the top of RTK_Surveyor.ino can be commented out to remove them from compilation. This will greatly reduce the firmware size and allow for faster development of functions that do not rely on WiFi or Bluetooth (serial menus, system configuration, logging, etc).

+**Note:** There are a variety of compile guards (COMPILE_WIFI, COMPILE_AP, etc) at the top of RTK_Surveyor.ino that can be commented out to remove them from compilation. This will greatly reduce the firmware size and allow for faster development of functions that do not rely on these features (serial menus, system configuration, logging, etc).
