BTIsVisible (Function)

In french: BTEstVisible

Allows you to find out whether a Bluetooth radio is visible.

Remark: A Bluetooth radio corresponds to a Bluetooth transmitter. This transmitter can correspond to a Bluetooth USB key or it can be an element included in a computer (laptop for example).

Caution: Bluetooth functions are not available in the Android emulator.

Example

bVisible is boolean
// Identifier of Bluetooth radios listed in a Table control
nRadioID is int
nRadioID = TABLE_Radios.COL_ID[TABLE_Radios]
// Checks whether the selected radio is visible
bVisible = BTIsVisible(nRadioID)
// Display
IF bVisible = True THEN
Trace("Visible")
ELSE
Trace("Not visible")
END
// Change the visibility
BTChangeVisibility(nRadioID, NOT bVisible)
