i'm newbie..
i want to phone call when i push the SW button,
button for a emergency call for elderly or children, women
i think two different way
1. push the button -> send data to my phone -> phone calling someone
i think UART is key, i'm keep translate datasheet but i can't understand well
2. ble deep sleep mode -> push the button -> re-activate ble -> software detect the ble's re-connection -> phone calling someone
these are possible things?
does any reference or something to study this?
plz it makes me hard days

You would need to setup the phone to run an app that calls outwards when the BLE triggers it either with a custom profile for BLE, or a declared profile on the BT SIG website: List of Bluetooth profiles - Wikipedia
The process of connecting the BLE will be up to your architecture choice of how you want the connection to be: constants, fast, low-power, etc.
Both of the methods you describe are feasible and implementable.
There are many devices that implement this, but most of the work, unfortunately, will be on the phone-app side of the devices.
The BLE device will merely send a button-press trigger signal to the phone, and the phone app/code will do the rest from the architecture standpoint.
