Is there some way to get 'SPBTLE-RF'. be discoverable again, without reset?

I have done a Bluetooth server that works well.

The client is connecting, interacting with the services and disconnecting.

On the disconnecting procedure, the server starts the command "Aci_Gap_Set_Discoverable".

In some cases, when the connection is not closed properly, the "SPBTLE-RF" chip returns a fail on "Aci_Gap_Set_Discoverable" command ( 0x0C: Command disallowed ).

It looks like the chip is stuck in some mode.
