Connecting to Oxitone 1000M
 Whenever a device (client/host) tries to connect for the first time to the watch, the watch will
vibrate and display a message to the user that a device (the device name will be displayed
on the screen) tries to connect to it.
 If the user presses the button (accepts the connection) the devices will be connected, and the
watch will start sending the measurement data to the host.
 If 15 seconds passed and the user did not accept the connection, the watch will reject the
connection request. The device that tried connecting to the watch will not be able to
connect for a whole minute (to prevent multiple connection requests).
 After the first time the user accepts a connection, the host ID is saved to the watch, and the
next time the same host will try to connect the user will not be asked to accept the
connection (the connection will be apporved automatically). The watch 'remembers' only
one host at a given time.

will vibrate and display a message to the user that a device (the device name will be displayed
on the screen) tries to connect to it.
 If the user presses the button (accepts the connection) the devices will be connected, and the
watch will start sending the measurement data to the host. The watch will display a blue BLE
symbol to indicate the watch is connected.
 If 15 seconds passed and the user did not accept the connection, the watch will reject the
connection request. The device that tried connecting to the watch will not be able to connect
for a whole minute (to prevent multiple connection requests).
 After the first time the user accepts a connection, the host ID is saved to the watch, and the
next time the same host will try to connect the user will not be asked to accept the
connection (the connection will be approved automatically). The watch 'remembers' only one
host at a given time.
Note: It is the user's responsibility to accept or reject a connection request, in order to make sure
his vital signs will not be transmitted to an unknown device.
In case the watch losses connection to the host device (disconnected), the BLE symbol will
turn white.
