Error of "Write not permitted" to descriptor, may be is not a real problem. In the "J-Link RTT Viewer" I detect the problem "Unable to find matching net for packet". There is a wrong unicast address in my commands. When I set unicast address correct, some notifications was appear. Screenshot:

I think it can't help me. In my case, I do success provision device. And then, I'm trying to send some command to vendor service (turn on led). There are steps of my case:
1). Scan unprovisioned device
2). Connect to device
3). Make provision device (send all commands to provision - success)
4). Disconnect from device

Next steps - work with provision device:
5). Scan provision device
6). Connect to device
7). When I connected and turn on default-way notification, I reveice message (0x) 01-01...then I check authenticated Beacon...
8).---- I think, that my problem is here
9). Send Application Key
10). Send command to vendor service

All the commands look like correct, but there are no messages received. In the android application, notifications for proxy-service are turning on by writing some value to descriptor. When I trying to do that - I've got an error "Write not permitted".

Without notifications, I can't see results of my commands. I don't know the reason of that error - it's a linux problem, or it's a java problem or may be I miss some important command to send before

Hi,

Just to clarify, are you trying to create a provisioner on your Raspberry PI?

I would suggest you look through Interactive PyACI script and the examples/tutorials for it.

I think that problem is in enable notification on MeshProxy GattService -> Out Characteristic(00002ade-0000-1000-8000-00805f9b34fb)

Debug information of Mesh mobile application, show this:

It enabled activated by write value to BluetoothGattDescriptor.

When I trying to do the same, I've got an error: Write Not Permitted!
