AssetTrackerRK
Alternative library for the Particle AssetTracker/Electron based on TinyGPS++
This is an alternative implementation of the library for the Particle Electron AssetTracker. I used my own [LIS3DH driver] (https://github.com/rickkas7/) and [TinyGPS++] (https://github.com/mikalhart/TinyGPSPlus).
I prefer the TinyGPS++ library as I find it to be more reliable, and my LIS3DH driver supports some more options including getting accelerometer data, direction sensing, and wake-on-move.
There's also an optional AssetTracker almost-drop-in replacement. I prefer to access the LIS3DH driver and TinyGPS++ directly, because they have many more features than the original AssetTracker library. But for initial testing, the replacement shim is pretty handy. Note the preNMEA() method always return an empty string, because TinyGPS++ doesn't export a function to get that information.

Also note: If you are using this directly from the Particle Firmware Libraries manager it will automatically include the LIS3DH driver as well. If you are manually copying the source from here, you will also need:

By the way, I highly recommend adding an external active GPS antenna and the CR1220 coin cell battery. With this combination, the wake-on-move and report GPS location example can get a GPS fix in 2 to 7 seconds!
Examples
The code should be straightforward to use. The examples include:
1 Simple GPS
Simple example of using the GPS to report the current location to serial and Publish to the cloud.
2 GPS Celullar On/Off
Like the previous example, but supports turning cellular on or off. Pressing the MODE button toggles the cellular connection.
3 Wake On Move
Wakes the Electron when moved and publishes the current location from the GPS.
4 Accelerometer Samples
Prints XYZ data from the accelerometer to the debug USB serial connection.
5 Accelerometer Direction
The LIS3DH accelerometer has the ability to detect when it's stable in one of 6 orientations. This code prints the current orientation to the debug USB serial connection.
6 Backward Compatible API
Example of using the original AssetTracker API with the this library.
Updates
Updated in 0.1.1
Fixed compatibility with system firmware 0.6.1. The Arduino compatibility in that version conflicted with the Arduino compatibility built into TinyGPS++.
Updated in 0.1.2
Added compatibility with AssetTracker v2. This is just basic compatibility with getting GPS data; more advanced options for controlling it will be added later.
