Per documentation here Low Power Design - Blues Wireless Developers I am looking to put my host to sleep and wake it up using card.attn function. The document mentions sending a card.attn request on host startup to verify the reason for the triggered attn signal. A wakeup from sleep looks like below.
{
"files": [
"timeout"
],
"set": true
}
I was wondering if there are any existing helper functions in the Arduino library or some example code for dealing with the array ?
Thanks,
Serge
