There is no Bluetooth there. It’s all network.
You said you have 2 mesh nodes? Each one has a different network name?
Let’s say mesh node 1 wifi network name is dog 1. Mesh node 2 that the Meitner is hardwired to, network name is dog 2.
Go to your ipad wifi settings, and select the network with the name that corresponds to the node that feeds the Meitner.
You should be good to go.
