More example

I am a newbie with rust. I would like to a sample/example of writing to a BLE characteristics with notify. I really appreciate if someone is kind enough give me a helping hand. Thank you,

Hi,
Would love for someone to show me how to pass a known ble MAC address string to the peripheral. Thank you.

I can't give you a full blown example, but the basic idea is to scan for peripherals from your central device (that is the adapter in ble terminology):

let predicate = ...
let p = central.peripherals().into_iter().find(predicate)

if you have a peripheral, scan for characteristics:

let chars = p.discover_characteristics()

then find your characteristic

let rx_char = chars
            .clone()
            .into_iter()
            .find(|c| RECEIVE_CHARACTERISTIC == c.uuid)
            .expect("Could not find given characteristic");

RECEIVE_CHARACTERISTIC is a UUID. From here, you can call methods like subscribe, send , on_notification and so on. Hope that helps.
