Our block diagram is consist of two sensors, one external microcontroller, and one DA14585 BLE.
Our main goal is to reduce power consumption, for that, we thought two types of case
Case i: By Keeping DA14585 BLE in sleep mode(Deep Sleep or Extended Sleep). When an external microcontroller sends an interrupt to DA14585 BLE it wakes up and starts advertising.
Case ii. Power off DA14585 BLE completely, When an external microcontroller sends an interrupt DA14585 BLE has to be powered on first and starts advertising.
The Case-i we have tested it is working as expected. For implementing Case-ii what sort of circuit elements do we required between an external microcontroller and DA14585 BLE microcontroller?
