I am definitely getting freezes still. Maybe it's just bad hardware, I'm going to try swapping components.

that flowchart is good stuff, I'll definitely refer to it in the future.

swapping to a 4.7uF cap seems to maybe have fixed the issue, I've only observed for a couple of hours so maybe it just likes the heat of the day here

I'm getting a hard freeze (even the hardware watchdog is failing to reset the device) during transmissions, I have code here:

https://github.com/Bokbot/incubot/tree/mysensor

its basically a pidloop controlling a lightbulb in an incubator for some eggs.

so long as I comment out the send lines like this:
send(msgHum.set(humidity, 1));

everything runs continuously, but with those lines included the thing freezes randomly after an inconsistent amount of time. Meaning it does transmit for a good fifteen minutes usually before freezing.

Has anyone else seen behavior like this?

I don't seem to be getting any replies here, so I'm moving to github here:
https://github.com/mysensors/Arduino/issues/480

Hello I've been using the arduino-mk Makefile for my project instead of using the IDE as I generally program using vim anyhow, why fire up the IDE when you can just 'make' and
'make upload'?

Anyhow, I'm also interested in this project. But when I combine the two I get errors like:

fatal error: MySensor.h: No such file or directory

my Makefile is pretty simplistic:

include /home/george/git/Arduino-Makefile/Arduino.mk
ARDUINO_LIBS     = SPI MySensors DHT

USER_LIB_PATH is computed to be:

- [DEFAULT]            USER_LIB_PATH = /home/thoth/sketchbook/libraries

and the MySensors folder is in there:

ls ~/sketchbook/libraries/MySensors 
core  drivers  examples  keywords.txt  library.json  library.properties  MyConfig.h  MySensor.h  tests

Is anyone else using the arduino-mk Makefile? And if so any hints as to what might be wrong here?

note I've tried with latest everything on Archlinux, and using a docker container with debian jessie here:
https://github.com/joshuacox/mkarduino

same result in both environments

*Note in debian I use this include line:

include /usr/share/arduino/Arduino.mk
