Graphical Analysis requires access to the Bluetooth radio system to connect to sensors wirelessly. If Graphical Analysis cannot access Bluetooth, it will report that Bluetooth is not enabled.<\/p>\n

This message is the same if Bluetooth is off system-wide, and also if Bluetooth is on but Graphical Analysis does not have permission to use Bluetooth. <\/p>\n<\/div>\n

Note: <\/strong>If Bluetooth is off, turn it on.<\/p>\n

Starting with macOS 11 and iOS\/iPadOS 13, applications require that you grant permission to the application to use Bluetooth. Normally Graphical Analysis requests this permission at first launch. If you dismiss the permissions dialog without granting permission, Graphical Analysis will be unable to use Bluetooth and will offer the above dialog even if Bluetooth is enabled for other applications. <\/p>\n
