The Dark Side Probe is about using the Dark Side Challenge software stack to collect information in a remote area, with a particular attention to battery life & power consumption
The current version consists of an Arduino Pro Mini managing a SIM7000E GSM+GPS module.
We have simply added the SIM7000 functionality by reusing (refactoring) most of the existing ESP8266 code.
What we are still missing is:
* to find out how to make the SIM7000 enter sleep mode
* reduce the time it takes to get a GSM connection (currently takes >10 min). The target is a few seconds, as we would like to achieve a year-long battery life.
* get GPS information from the SIM7000, possibly using Assisted GPS
