BTChangeVisibility (Function)

In french: BTChangeVisibilité

Changes the visibility of a Bluetooth radio.

Note: 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).

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)

Syntax

Syntax that can be used in Windows Hide the details

<Result> = BTChangeVisibility(<Radio identifier> , <New status>)

<Result>: Boolean

True if the change of visibility was successfully performed,
False otherwise. ErrorInfo returns more details about the problem.

<Radio identifier>: Integer

Identifier of Bluetooth radio to use. This identifier is returned by BTListRadio.

<New status>: Boolean

True in order for the radio to become visible,
False in order for the radio to be hidden.

Remarks

Visible radio and connection request

A visible Bluetooth radio automatically accepts the connection requests. When BTChangeVisibility is used to make the radio visible, the call to BTChangeConnectivity is automatically performed.

Limitation

Only the Microsoft Bluetooth stack is supported by this function. To find out the stack used, call BTStack.

See Which stacks to use? for more details
