I believe the issue is caused by the trailing space above. > - "@apache-mynewt-core/mgmt/imgmgr" > - "@apache-mynewt-core/mgmt/newtmgr" > - "@apache-mynewt-core/mgmt/newtmgr/transport/ble" > - "@apache-mynewt-core/net/nimble/controller" > - "@apache-mynewt-core/net/nimble/host" > - "@apache-mynewt-core/net/nimble/host/services/ans" > - "@apache-mynewt-core/net/nimble/host/services/gap" > - "@apache-mynewt-core/net/nimble/host/services/gatt" > - "@apache-mynewt-core/net/nimble/host/store/ram" > - "@apache-mynewt-core/net/nimble/transport/ram" > - "@apache-mynewt-core/sys/console/full" > - "@apache-mynewt-core/sys/log/full" > - "@apache-mynewt-core/sys/stats/full" > - "@apache-mynewt-core/sys/sysinit" > - "@apache-mynewt-core/sys/id" > > > I also created a nrf52 target for blep. > > Am I missing something?

That is a good way to get started with a new app. I don't anticipate any more errors after this one is solved. By the way, there is an unfortunate bug in the current version of newt. The dependency resolution error message gets the depender name wrong; it prints the dependee package instead! Chris
