Scanner is disabled after provision completes with PB-GATT enabled with 10 second delay workaround

[JonasJ]

A device that is provisioned with PB-GATT enabled stops receiving mesh packets after the provision is complete.

When the provisioning process is complete nrf_mesh_disable() is called. Later when the SD has been restarted nrf_mesh_enable() is called.

nrf_mesh_disable() will call scanner_disable() but nrf_mesh_enable() never calls scanner_enable().

This patch solves the problem.

This is a bug was introduced with the previous workaround for the 10 second delay during provision. https://devzone.nordicsemi.com/f/nordic-q-a/43992/10-second-delay-after-pb-gatt-completed-until-first-mesh-proxy-service-advertisement

Thanks for providing this patch! I have reported this internally. We have another workaround that also seems stable here:

+        }
         else
         {
             notify_stop();

And replace action_switch() in bearer_handler_timer_irq_handler() with this code:

 if (m_stopped)
        {
            timeslot_stop();
        }
        else
        {
            action_switch();
        }

Could you try using this fix instead of the workaround mentioned by Hung Bui in the DevZone case that you mentioned?

Thanks. This works.

Just want to let you know that the patch has been updated.
