+  Use ESP32 WiFi to get AssistNow Online data from u-blox Thingstream
+  By: SparkFun Electronics / Paul Clark
+  Date: November 24th, 2021
+  License: MIT. See license file for more information but you can
+  basically do whatever you want with this code.
+
+  This example shows how to obtain AssistNow Online data from u-blox Thingstream over WiFi
+  and push it over I2C to a ZED-F9x.
+
+  You will need to have a token to be able to access Thingstream. See the AssistNow README for more details.
+
+  Update secrets.h with your:
+  - WiFi credentials
+  - AssistNow token string
+
+  Feel like supporting open source hardware?
+  Buy a board from SparkFun!
+  SparkFun Thing Plus - ESP32 WROOM: https://www.sparkfun.com/products/15663
+  ZED-F9P RTK2: https://www.sparkfun.com/products/16481
+  SparkFun GPS Breakout - ZOE-M8Q (Qwiic): https://www.sparkfun.com/products/15193
+
+  Hardware Connections:
+  Plug a Qwiic cable into the GNSS and a ESP32 Thing Plus
+  If you don't have a platform with a Qwiic connection use the SparkFun Qwiic Breadboard Jumper (https://www.sparkfun.com/products/14425)
+  Open the serial monitor at 115200 baud to see the output
