JSR-82

Hi I try to edit a service record I created with the Connector.open( url ) function but i get error when editing/changing to DataElement[ProtocolDescriptorList] = 17.

BT: L2CapRegisterPsm failed: 12
Server (S2): java.io.IOException: L2CapRegisterPsm failed: 12

the updateRecord(ServiceRecord srvRecord) says: "srvRecord must not have changed the PSM value from the PSM value that is currently in the SDDB version of this service record."

if this is the case and cannot edit existing service record, then how to create service record with the correct PSM in the first place?

Please help. thank you.
