Well huh. One of the unwritten rules of Buttplug/ScriptPlayer is that we expect you to have the 1.2 Firmware, which currently can only be loaded by the FeelConnect app, so that would've been required. We have enough information to write our own firmware loader but that's gonna take some time. I don't see /why/ there should be a connection problem, even if you're on 1.1 firmware though. Obviously the device is booting and running the firmware since it just blinks blue.
I suppose it could be that with the 1.1 firmware, it may also not show up as "Launch"? We've had people manage to use Buttplug/ScriptPlayer with a 1.0/1.1 firmware Launch though. So, continuing to stab in the dark: The Launch should still use the same services, so on the nordic radios app, if you look through the devices with no name and see one with a service GUID of
that's the Launch, in which case maybe it just doesn't have a name for some reason.
