allowIvIndexRecoveryOver42

According to Bluetooth Mesh Profile 1.0.1, section 3.10.5, if the IV Index of the mesh network increased by more than 42 since the last connection (which can take at least 48 weeks), the Node should be re-provisioned. However, as this library can be used to provision other Nodes, it should not be blocked from sending messages to the network only because the phone wasn't connected to the network for that time. This flag can disable this check, effectively allowing such connection.

The same can be achieved by clearing the app data (uninstalling and reinstalling the app) and importing the mesh network. With no "previous" IV Index, the library will accept any IV Index received in the Secure Network beacon upon connection to the GATT Proxy Node.
