ARDUINOJSON_USE_LONG_LONG must be set to 1

[schnef]

I had to set ARDUINOJSON_USE_LONG_LONG to 1 before including Thing.h. See ARDUINOJSON_USE_LONG_LONG. Using 64 bits instead of 32, is that an issue?

Lib versions used:
AdruinoJson 6.15.2
webthing-arduino 0.11.5

Board:
ITEAD sonoff basic

Hi @schnef,

I've also had to use this on Ubuntu with VS Code but not on Windows with Arduino IDE, so I'm not sure what makes this required. In any case I've noticed any difference in performance or behaviour.

Cheers 🙂

I'm running on a Linux Debian 10 64 bit machine. That's the only link I see with long_long

I recently committed a fix for that, which should be in the next release.
