Can I send card.attn directly to the notecard?

Hi,
My MCU sometimes hangs, and I want to restart it using card.attn. Can I send a JSON to Notecard via Notehub, so the MCU will not need to process the JSON?

Hi @tomnorm,

You can use a reserved environment variable to restart a host:

Look up the environment variables that start with _restart_host.

Thanks,
