Protocol Details
Launch
- STEP 1: find device
- STEP 1a: query device capability
- STEP 2: setup control channel to remote device
- STEP 2a: device challenge / device pairing
- STEP 3: launch app / page
- STEP 4: setup communication channel
- STEP 5: close control channel
Terminate
- STEP 1: setup control channel to remote device
- STEP 1a: complete challenge with stored information
- STEP 2: terminate app / page via session Id
- STEP 3: close control channel
Reconnect
- STEP 1: setup control channel to remote device
- STEP 1a: complete challenge with stored information
- STEP 2: reconnect app / page via session Id
- STEP 3: setup communication channel
- STEP 4: close control channel
