Hi,
I'm using 2 nRF52840 DK to run the Serial Interface example, please refer to the link
- Serial ( named it as DK-1)
- Light switch server (name it as DK-2)
And It works fine for me, able to completed provision and stores the DB setting into example_database.json and then powers off/on the Light switch server.
Let's say if I restart the DK-1, then how to connect back the Light switch server? I tried to load the DB setting from example_database.json again and below is the results
- db = MeshDB("database/example_database.json")
- db.provisioners
- Out[2]: [{'name': 'BT Mesh Provisioner', 'UUID': bytearray(b'\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00'), 'allocated_unicast_range': [{'low_address': 0010, 'high_address': 7fff}], 'allocated_group_range': [{'low_address': c000, 'high_address': feff}]}]
- p = Provisioner(device, db)

I know once the DK-2 go through the provision, the device will become a node of mesh network and it will not appear when we tried to scan it, which you can see in step 4 (i.e. p.scan_start()) --> none of device appear in the list. so that Step 6 found the error.
My Question is how DK-1 connect back to the mesh network where it forms the mesh network earlier?
I don't see the NetKey store in the example_database.json, is this the reason why DK-1 failed to resume the connection?
