+U-blox makes some incredible GPS receivers covering everything from low-cost, highly configurable modules such as the SAM-M8Q all the way up to the surveyor grade ZED-F9P with precision of the diameter of a dime. This library focuses on configuration and control of u-blox devices over I2C (called DDC by u-blox) and Serial. The UBX protocol is supported over both I2C and serial, and is a much easier and lighterweight interface to a GPS module. Stop parsing NMEA data! And simply ask for the datums you need.
+
+This library can be installed via the Arduino Library manager. Search for **SparkFun Ublox**.
+
+Although not an integrated part of the library, you will find an example of how to communicate with the older series 6 and 7 modules in the [examples folder](./examples/Series_6_7).
+
+Max (400kHz) I2C Support
+-------------------
+
+To achieve 400kHz I2C speed please be sure to remove all pull-ups on the I2C bus. Most, if not all, u-blox modules include pull ups on the I2C lines (sometimes called DDC in their manuals). Cut all I2C pull up jumpers and/or remove them from peripheral boards. Otherwise, various data glitches can occur. See issues [38](https://github.com/sparkfun/SparkFun_Ublox_Arduino_Library/issues/38) and [40](https://github.com/sparkfun/SparkFun_Ublox_Arduino_Library/issues/40) for more information. If possible, run the I2C bus at 100kHz.

+
+Polling vs. Auto-Reporting
+--------------------------
+
+This library supports two modes of operation for getting navigation information with the `getPVT`
+function (based on the `UBX_NAV_PVT` protocol packet): polling and auto-reporting.
+
+The standard method is for the sketch to call `getPVT` (or one of the `getLatitude`, `getLongitude`,
+etc. methods) when it needs a fresh navigation solution. At that point the library sends a request
+to the GPS to produce a fresh solution. The GPS then waits until the next measurement occurs (e.g.
+once per second or as set using `setNavigationFrequency`) and then sends the fresh data.
+The advantage of this method is that the data received is always fresh, the downside is that getPVT
+can block until the next measurement is made by the GPS, e.g. up to 1 second if the nav frequency is
+set to one second.
+
+An alternate method can be chosen using `setAutoPVT(true)` which instructs the GPS to send the
+navigation information (`UBX_NAV_PVT` packet) as soon as it is produced. This is the way the older
+NMEA navigation data has been used for years. The sketch continues to call `getPVT` as before but
+under the hood the library returns the data of the last solution received from the GPS, which may be
+a bit out of date (how much depends on the `setNavigationFrequency` value).
+
+The advantage of this method is that getPVT does not block: it returns true if new data is available
+and false otherwise. The disadvantages are that the data may be a bit old and that buffering for
+these spontaneus `UBX_NAV_PVT` packets is required (100 bytes each). When using Serial the buffering
+is an issue because the std serial buffer is 32 or 64 bytes long depending on Arduino version. When
+using I2C the buffering is not an issue because the GPS device has at least 1KB of internal buffering
+(possibly as large as 4KB).
+
+As an example, assume that the GPS is set to produce 5 navigation
+solutions per second and that the sketch only calls getPVT once a second, then the GPS will queue 5
+packets in its internal buffer (about 500 bytes) and the library will read those when getPVT is
+called, update its internal copy of the nav data 5 times, and return `true` to the sketch. The
+sketch calls `getLatitude`, etc. and retrieve the data of the most recent of those 5 packets.

+How I2C (aka DDC) communication works with a uBlox module
+===========================================================
+
+When the user calls one of the methods the library will poll the Ublox module for new data.
+
+* Wait for a minimum of 25 ms between polls (configured dynamically when update rate is set)
+* Write 0xFD to module
+* Read two bytes (0xFD and 0xFE) for bytes available
+* If 0x7F or 0xFF then no bytes are available
+* Otherwise, read number of bytes and process into NMEA, UBX, or RTCM frame.
+* If checksum is valid, flag frame as complete.
+
+This library was originally written to use the I2C interface but Serial has been implemented as well.
+
+How data is processed by this library
+===========================================================
+
+A method will call **sendCommand()**. This will begin waiting for a response with either **waitForACKResponse()** or **waitForNoACKResponse()** depending on the command we have sent (CFG commands generate an ACK where others like PVT do not).
+
+Once **waitForACKResponse()** or **waitForNoACKResponse()** is called the library will start checking the ublox module for new bytes. These bytes may be part of a NMEA sentence, an RTCM sentence, or a UBX packet. The library will file each byte into the appropriate container. Once a given sentence or packet is complete, the appropriate processUBX(), processNMEA() will be called. These functions deal with specific processing for each type.
+
+Note: When interfacing to a ublox module over I2C **checkUbloxI2C()** will read all bytes currently sitting in the I2C buffer. This may pick up multiple UBX packets. For example, an ACK for a VALSET may be mixed in with an auto-PVT response. We cannot tell **checkUbloxI2C()** to stop once a given ACK is found because we run the risk of leaving bytes in the I2C buffer and losing them. We don't have this issue with **checkUbloxSerial()**.
+
+**processUBX()** will check the CRC of the UBX packet. If validated, the packet will be marked as valid. Once a packet is marked as valid then **processUBXpacket()** is called to extract the contents. This is most commonly used to get the position, velocity, and time (PVT) out of the packet but is also used to check the nature of an ACK packet.
+
+Once a packet has been processed, **waitForACKResponse()/waitForNoACKResponse()** makes the appropriate decision what to do with it. If a packet satisfies the CLS/ID and characteristics of what **waitForACKResponse()/waitForNoACKResponse()** is waiting for, then it returns back to sendCommand. If the packet didn't match or was invalid then **waitForACKResponse()/waitForNoACKResponse()** will continue to wait until the correct packet is received or we time out. **sendCommand()** then returns with a value from the **sfe_ublox_status_e** enum depending on the success of **waitForACKResponse()/waitForNoACKResponse()**.
+
+If we are getting / polling data from the module, **sendCommand()** will return **SFE_UBLOX_STATUS_DATA_RECEIVED** if the get was successful.
+
+If we are setting / writing data to the module, **sendCommand()** will return **SFE_UBLOX_STATUS_DATA_SENT** if the set was successful.
+
+There are circumstances where the library can get the data it is expecting from the module, but it is overwritten (e.g. by an auto-PVT packet) before **sendCommand()** is able to return. In this case, **sendCommand()** will return the error **SFE_UBLOX_STATUS_DATA_OVERWRITTEN**. We should simply call the library function again, but we will need to reset the packet contents first as they will indeed have been overwritten as the error implies.

+  This example shows how to configure the library and U-Blox for serial port use as well as
+  switching the module from the default 9600 baud to 38400.
+
+  Note: Long/lat are large numbers because they are * 10^7. To convert lat/long

+  This example powers up the GPS and reads the fix.

+  The code then sets four geofences around that position with a radii of 5m, 10m, 15m and 20m with 95% confidence.
+  The code then monitors the geofence status.
+  The LED will be illuminated if you are inside the _combined_ geofence (i.e. within the 20m radius).

+  basically do whatever you want with this code.
+
+  This example shows how to put the Ublox module into power save mode and then
+  query its lat/long/altitude. We also turn off the NMEA output on the I2C port.
+  This decreases the amount of I2C traffic dramatically.
+
+  ** When it is able to ** the module will reduce its current draw.
+  For the ZOE-M8Q with a passive antenna, you should see the current drop
+  from (approx.) 25-28mA to (approx.) 9mA when power save mode kicks in.
+
+  Note: this will fail on the ZED (protocol version >= 27) as UBX-CFG-RXM is not supported
+
+  Note: Long/lat are large numbers because they are * 10^7. To convert lat/long
+  to something google maps understands simply divide the numbers by 10,000,000. We
+  do this so that we don't have to use floating point numbers.
+
+  Leave NMEA parsing behind. Now you can simply ask the module for the datums you want!

+  Set Dynamic Model

+  Date: January 3rd, 2019
+  License: MIT. See license file for more information but you can
+  basically do whatever you want with this code.
+
+  This example shows how to change the Ublox module's dynamic platform model and then
+  query its lat/long/altitude. We also turn off the NMEA output on the I2C port.
+  This decreases the amount of I2C traffic dramatically.
+
+  Possible values for the dynamic model are: PORTABLE, STATIONARY, PEDESTRIAN, AUTOMOTIVE,
+  SEA, AIRBORNE1g, AIRBORNE2g, AIRBORNE4g, WRIST, BIKE
+
+  Note: Long/lat are large numbers because they are * 10^7. To convert lat/long
+  to something google maps understands simply divide the numbers by 10,000,000. We
+  do this so that we don't have to use floating point numbers.
+
+  Leave NMEA parsing behind. Now you can simply ask the module for the datums you want!

+  Powering off a ublox GPS module
+  By: bjorn
+  unsurv.org
+  Date: July 20th, 2020
+  License: MIT. See license file for more information but you can
+  basically do whatever you want with this code.
+
+  This example shows you how to turn off the ublox module to lower the power consumption.
+  There are two functions: one just specifies a duration in milliseconds the other also specifies a pin on the GPS device to wake it up with.
+  By driving a voltage from LOW to HIGH or HIGH to LOW on the chosen module pin you wake the device back up.
+  Note: Doing so on the INT0 pin when using the regular powerOff(durationInMs) function will wake the device anyway. (tested on SAM-M8Q)
+  Note: While powered off, you should not query the device for data or it might wake up. This can be used to wake the device but is not recommended.
+        Works best when also putting your microcontroller to sleep.

+
+  Hardware Connections:
+  Plug a Qwiic cable into the GPS and a BlackBoard.
+  To force the device to wake up you need to connect to a pin (for example INT0) seperately on the module.

+  Reading lat, long and UTC time via UBX binary commands - no more NMEA parsing!

+  SparkFun Electronics
+  Date: June 16th, 2020
+  License: MIT. See license file for more information but you can
+  basically do whatever you want with this code.
+
+  This example shows how to query a Ublox module for its lat/long/altitude. We also
+  turn off the NMEA output on the I2C port. This decreases the amount of I2C traffic 
+  dramatically.
+
+  Note: Long/lat are large numbers because they are * 10^7. To convert lat/long
+  to something google maps understands simply divide the numbers by 10,000,000. We 
+  do this so that we don't have to use floating point numbers.
+
+  Leave NMEA parsing behind. Now you can simply ask the module for the datums you want!

+  Configuring the GPS to automatically send HPPOSLLH position reports over I2C
+  By: Paul Clark
+  Date: October 27th 2020

+  Based on an earlier example:
+  By: Nathan Seidle and Thorsten von Eicken
+  SparkFun Electronics
+  Date: January 3rd, 2019
+  License: MIT. See license file for more information but you can
+  basically do whatever you want with this code.
+
+  This example shows how to configure the U-Blox GPS the send navigation reports automatically
+  and retrieving the latest one via getHPPOSLLH. This eliminates the blocking in getHPPOSLLH while the GPS
+  produces a fresh navigation solution at the expense of returning a slighly old solution.
+
+  This can be used over serial or over I2C, this example shows the I2C use. With serial the GPS
+  simply outputs the UBX_NAV_HPPOSLLH packet. With I2C it queues it into its internal I2C buffer (4KB in
+  size?) where it can be retrieved in the next I2C poll.

+  This example shows how to set the static position of a receiver
+  using an Earth-Centered, Earth-Fixed (ECEF) location. This is the
+  output from a long (24 hour+) survey-in. Setting the static position
+  immediately causes the receiver to begin outputting RTCM data (if
+  enabled), perfect for setting up your own RTCM NTRIP caster or CORS.

+paragraph=An Arduino Library to enable both I2C and Serial communication for both NMEA reception and binary UBX sending to u-blox modules. Useful for interfacing to the <a href="https://www.sparkfun.com/products/15136">SparkFun GPS-RTK2</a> ZED-F9P, <a href="https://www.sparkfun.com/products/14980">SparkFun GPS-RTK</a> NEO-M8P-2, the <a href="https://www.sparkfun.com/products/15210">SparkFun SAM-M8Q</a>, and the <a href="https://www.sparkfun.com/products/15193">SparkFun ZEO-M8Q</a>. Library also works with other u-blox based boards. <br><br>The ZED-F9P and NEO-M8P-2 modules are top-of-the-line modules for high accuracy GNSS and GPS location solutions including RTK. The ZED-F9P is unique in that it is capable of both rover and base station operations allowing the module to become a base station and produce RTCM 3.x correction data.
