I'm attempting to get our wearable remote to interact with a GoPro using their API and am getting the error in the subject line when attempting to start scanning. I've checked out a couple of resolutions of this error (wrong parameters, increase the size of the scan buffer, etc) but still getting the error. Does anybody have an example for this? Code attached...
