The
syncmessage function sends a string message from one device to another device that is acting as a
Bluetooth server. The string expression
message_name identifies the message, and an optional string expression
message_value defines a value associated with the message. The client device sends this message to a Bluetooth server.
The application running on the Bluetooth server must have a
user-defined function with the name
OnSyncMessage that has two string parameters and returns a string. While the
syncserver function is running, the
OnSyncMessage function is called anytime a message is received and the return value of that function is returned to the Bluetooth client.
The function returns the message returned by the
OnSyncMessage function running on the Bluetooth server. If no message is returned, a blank string is returned.
