Notecard wakeup by Host uC

Firmware

Can a host uC wakeup a Notecard by sending command via TX/RX serial?

If not, can a Host device wake up a Notecard?

Thanks

Pat,

The notecard never sleeps. It is always awake, at a current level of about 8uA if it’s just waiting for a request. It is always responsive to requests on I2C and RX/TX serial at 9600 bps.

In fact, even if you know you won’t be sending any requests to the notecard we don’t recommend that you ever remove power from it. In this way the Notecard can easily keep time, keep track of its next scheduled sync, and similar background tasks.

Hope this helps,

Carl
