The Platformio.ini below is the only working one, if you want to compile without trouble please change accordingly !
The older " platform = asrmicro650x " in the original code is no longer valid from Heltec cubecell.

[env]
platform = heltec-cubecell
board = cubecell_gps
framework = arduino
monitor_speed = 115200
lib_deps =
https://github.com/dj1an/APRS-Decoder-Lib.git#cubecell
paulstoffregen/Time @ 1.6

[env:cubecell_gps]
#upload_port = /dev/ttyUSB1
#monitor_port = /dev/ttyUSB1
build_flags = -Werror -Wall

Just did a few Measurements with the actual Firmware:
Current was measured in between Battery and the Cubecell Board without USB Power.

1. LCD on, GPS: on: 50-63mA
2. LCD on, GPS off: 17.9mA
3. LCD and GPS off: 11.27mA
4. LCD, GPS and Radio off, CPU Sleepmode : 11.17 mA

As there is no On/Off switch on the Device itself, we have to fully rely on the Sleepmode for Standby use.
The advertised 21uA from the Datasheet is not nearly reached, so the Battery gets drained fast.

Add a static Beaconing Profile with fixed preconfigured Position without GPS

I've let the board run for a while at a stationary position. It seems to move about, I assume this might be a GPS issue, but I have a feeling it might be the conversion from GPS Coordinates to APRS packet format. It's not TOO far off but will test this further.

Is it really necessary to use Heltecs LoRaWan_APP for controlling the Hardware?
All example Codes and other Projects i found are using this.
Would be cleaner to directly access the Hardware.
