Bluetooth on current

[mlh%goathill.org@localhost (MLH)]

My old Android phone which allowed writes to the removable sd card
was stolen and I had to get a new one, which only allows certain
things to be written there (not enough).

I can't find any MTP utilities that would allow access via usb that
work and I don't have wireless on the NetBSD box so have been
attempting to get bluetooth working (typically via OBEX).

I set up rc.d/bluetooth using a usb bt dongle and it is running on
NetBSD 8.99.17 amd64.

I appear to have successfully paired and bthcid appears to be working :
$ btkey -a phone -d ubt0
    device: xx:xx:xx:xx:xx:xx (ubt0)
    bdaddr: xx:xx:xx:xx:xx:xx (phone)

$ sdpquery -a phone browse
etc. work as advertised

When I try to send a file from the phone, hcidump logs:

and the phone reports "Connection failed" - no file sent

obexftp, etc. also fail:

$ obexftp -b phone -l
Scanning for phone ...

unknown error on connect

What am I missing?
Anyone else able to transfer files with a recent Android phone these days?
