Hello,
Can you please provide details of configuring DSPS device project for EXTERNAL_WAKEUP via UART CTS.
From AN-B-026 : External Processor Wake-up Mechanisms document the feature is described for full embed only. It is not clear how to apply it to DSPS.
The idea is to wake up DSPS (device side) by an external processor, transmit a burst of data and than return it to extended sleep.
Your help will be greatly appreciated.

Hi imalamoud,
RTS(ext proc) -> CTS(wake-up pin)
CTS(ext proc) -> RTS(set when completely woken up)
The idea is, when the da is in permanent sleep (no connection) and the external processor wants to send data, the external processor should set his RTS to on. The "on" state of the RTS should wake up the da (CTS pin to the da) and will start the wake up procedure. When the da is awake will set its RTS to "on" in order to indicate that he is ready to receive data (remember that if the da isn't connected and is just woken up it should advertise directly to a host and connect). This is just an idea of how to apply this kind of thing since there's no implementation for this yet.
Thanks MT_dialog
