Hi all: 
 Q:When i reboot the board which burn the serial project , how to add the device key to serial board again? 
 I use PYACI to control the board which burn the serial code 
 SDK for mesh:v2.0.1 
 
 Best regard.

Sorry for the delayed response. Just finished testing: everything works fine if you follow the guide like stated until sc.set(True). I tested with one serial board & one light switch server board. Remember to enable PERSISTENT_STORAGE on both examples. Then, power cycle the serial board & enter the following commands: 
 python interactive_pyaci.py -d COM1 --no-logfile
db = MeshDB("database/example_database.json")

cc = ConfigurationClient(db)
device.model_add(cc)
cc.publish_set(8, 0)
cc.composition_data_get()
cc.appkey_add(0)
cc.model_app_bind(db.nodes[0].unicast_address, 0, mt.ModelId(0, 0x59))
sc = SimpleOnOffClient()
device.model_add(sc)
sc.publish_set(0, 0)
sc.set(True) Since the provisioning has already been done, you do not need to do this part after you power cycled the serial board. Everything should work fine then.

This is something the mesh team might consider implementing in the future. For now, what you can do is enable PERSISTENT_STORAGE in the mesh serial example. You should be able to follow the whole interactive mesh provisioning example & then power cycle the serial board. 
 Another application engineer & I tested by following all of the steps, including cc.composition_data_get(). We used the serial example & a light switch server to test. Then, we power cycled the serial board & ran the following commands: 
 python interactive_pyaci.py -d COM1 --no-logfile
db = MeshDB("database/example_database.json")
cc = ConfigurationClient(db)
device.model_add(cc)
cc.publish_set(8, 0)
cc.composition_data_get() 
 where 8 is the devkey handle & 0 is the address handle from when you provisioned the first light client (i.e. p.provision(name="Light bulb")). 
 You may need to update DSM_DEVICE_MAX & DSM_FLASH_PAGE_COUNT, depending on how many devices you want to test with. I would recommend testing with two devices first, as I mentioned above.
