bluetooth lowenergy - Can an Android app discover a local BLE GATT server?

Question

If Android app A sets up a BLE GATT server, can Android app B (on the same device) discover and connect to that GATT server as a client?

Answer 1

No this shouldn't be possible because Bluetooth doesn't allow a device to connect to itself. I can't find in the spec where it specifically states this, but I have tried to do this using different Bluetooth stacks in the past and I wasn't able to.
