I’ve read lots of people at all stages of development with the mDot as a Node, but precious little about people actually getting them into the field.
I’ve successfully used the Microchip DM164139 Mote to get some small installations off the ground, but am looking elsewhere because of its poor power supply (inefficient, small operating range).
How does the mDot stack up against the following criteria, to get up to a hundred nodes into the field operating through TTN?
- Is the LoRaWAN stack buggy or feature complete?
- Is there support for the AU regional parameters?
- Is deep sleep effective for extremely low current draw?
- Is it easy to wake from sleep periodically?
- Is the mbed learning curve steep or can most of it be stripped out?
- Is the dev environment, including programmer and IDE, cheap, simple and stable?
- Is it easy to sample a couple of analog channels, including battery voltage?
- Is it easy to commission individual units with unique ids and shared keys?
- Is it easy to interface to a battery supply?
- Is it easy to mount the board in a custom enclosure and attach an antenna?
- Is radio performance satisfactory?
It’s often so hard to evaluate hardware platforms without spending months butting up against all their imperfections. Hoping I can lean on the community and avoid too many dead ends, and give back where I can.
