bluetooth module ✔ should describe basic constants

adapter ✔ should have availability ✔ should list adapters

device ✔ should return a device with requestDevice ✔ should have device properties ✔ should have gatt properties 1) should connect and disconnect 2) "before each" hook for "should have disconnect event"

devices 3) should return no devices with getDevices 4) should connect and disconnect 5) should return one device with getDevices after a request 6) should forget devices

all devices 7) should return all devices with getDevices

services 8) "before each" hook for "should get services" 9) "after each" hook for "should get services"

characteristics 10) "before each" hook for "should get characteristics" 11) "after each" hook for "should get characteristics"

descriptors 12) "before each" hook for "should get descriptors" 13) "after each" hook for "should get descriptors"

bluetoothuuid ✔ should get service ✔ should get characteristic ✔ should get descriptor ✔ should get canonical uuid
