看到别人提到sdptool，去查了查，是个蓝牙方面的工具。
1.
sdptool(1) – Linux man page

Synopsis
sdptool [options] {command} [command parameters …]
Description
sdptool provides the interface for performing SDP queries on Bluetooth devices, and administering a local sdpd.
Commands
The following commands are available. In all cases bdaddr specifies the device to search or browse. If local is used for bdaddr, then the local sdpd is searched.
Services are identified and manipulated with a 4-byte record_handle (NOT the service name). To find a service’s record_handle, look for the "Service RecHandle" line in the search or browse results
- search [–bdaddr bdaddr] [–tree] [–raw] [–xml] service_name
- Search for services..

- FTP, HS, HF, HFAG, SAP, NAP, GN, PANU, HCRP, HID, CIP, A2SRC, A2SNK, AVRCT, AVRTG, UDIUE, UDITE and SYNCML.
- browse [–tree] [–raw] [–xml] [bdaddr]
- Browse all available services on the device specified by a Bluetooth address as a parameter.
- records [–tree] [–raw] [–xml] bdaddr
- Retrieve all possible service records.
- add [ –handle=N –channel=N ]
- Add a service to the local sdpd.
- You can specify a handle for this record using
- the –handle option.
- You can specify a channel to add the service on
- using the –channel option.
- del record_handle
- Remove a service from the local sdpd.
- get [–tree] [–raw] [–xml] [–bdaddr bdaddr] record_handle
- Retrieve a service from the local sdpd.
- setattr record_handle attrib_id attrib_value
- Set or add an attribute to an SDP record.

2.看到其中有个：
OPUSH
感觉像是：
OPP
但是不确定。
后来是参考了：
List of Bluetooth profiles – Wikipedia, the free encyclopedia
Object Push Profile (OPP)
A basic profile for sending "objects" such as pictures, virtual business cards, or appointment details. It is called push because the transfers are always instigated by the sender (client), not the receiver (server).
OPP uses the APIs of OBEX profile and the OBEX operations which are used in OPP are connect, disconnect, put, get and abort. By using these API the OPP layer will reside over OBEX and hence follow the specifications of the Bluetooth stack.
确定此处的：
OPUSH就是OPP==Object Push Profile==用于发送传输文件的profile

# sdptool search OPUSH
Inquiring …
Searching for OPUSH on 00:1F:01:28:B2:36 …
Service Name: OBEX Object Push
更加确定了：
OPUSH==OPP
