I am using TC21 and DS3678.
I installed "Stage Now Ver 4.3" referring to this URL in order to set the trigger of DS3678 to "Wake up Source".
Since TC21 and DS3678 are connected by Bluetooth, I would like to use "BLUETOOTH_REMOTE_TRIGGER_1", but even if I proceed by referring to the contents of the URL, there is no key selection to change "BLUETOOTH_REMOTE_TRIGGER_1".
MX of TC21 is 10, so it is supported.
Please let me know if you need any other steps in "Stage Now".
