Project CubeCell
Low-power LoRaWAN Board
Status	In progress

Intro

This page is about the CubeCell board from heltec.org, aka HTCC-AB01

the github page for the Arduino code

What I'd like to investigate:

• Does it have an RTC? YES, it appears so
• --Can we run the arduino-lmic library on this? NO, probably not in the short term--
• --Can we compile the code with platformio? YES--
• Use this board for my LoraBatBox
• Video review by Andreas Spiess

Plans for immediate future:

• get the LoRaWAN example running, in OTAA (or restored OTAA)
• get LoRaWAN time synchronisation protocol running, figure out RTC API
• investigate if wake up can be done by pin too (not just timer)

Hardware

Features:

• based on an ASR605x (ARM cortex M0+ core) + SX1262(?) radio chip
• low power, only microamps sleep current
• battery connection
• solar cell connection
• pinout

Software

Example code:

• LoraWan example code
• A basic platformio demo project is available at https://github.com/bertrik/cubecelldemo

What I'd like to do for a LoraBatBox:

• register with OTAA (and remember the session keys)
• wake up when there is movement sensed by the PIR
• keep track of times when movement was detected (in wall-clock time)
• send activity (say) once per hour to TTN
