/*
Use ESP32 WiFi to get the L-Band dynamic keys from PointPerfect, allowing a ZED-F9x to use
the PMP data from a NEO-D9S correction data receiver.
By: SparkFun / Paul Clark
Based on original code by: u-blox AG / Michael Ammann
Date: March 17th, 2022
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 the L-Band dynamic keys from PointPerfect over ESP32 WiFi
and push them over I2C to a ZED-F9x. The ZED will then be able to decrypt the PMP correction data
from a NEO-D9S correction data receiver.
You can copy the keys directly from the Thingstream portal and paste them into your code - the
previous example shows how to do this - but calculating the "valid from" week and time is a chore.
This example requests the keys for you (using your client key and certificates) via MQTT.
It prints them too, so you can copy and paste them into the previous example if you wish.
You will need to have a valid u-blox Thingstream account and have a PointPerfect L-Band or L-Band + IP
Location Thing and payed plan.
Thingstream offers SSR corrections to SPARTN capable RTK receivers such as the u-blox ZED-F9 series
in continental Europe and US. Their Network is planned to be expanded to other regions over the next years.
