Chapter 2 – AT Commands
OPP Client Commands Introduction
The following OPP (Object Push Profile) commands allow the radio to be used as an OPP client, enabling it
to manipulate files on an OPP server. As the client, the device will initiate the connection with the server;
e.g., a PC, PDA, or cell phone. After making a connection, the device can push and pull objects.
Note: To achieve the maximum data throughput of 30kbps in OPP client mode, execute an ATUCL
command prior to making an OPP connection to put the radio in idle mode. If the radio is not in idle mode,
the data throughput will be approximately 15kbps.
OPP Connect/Disconnect Commands
DOPP Dial OPP
This command creates a connection to the OPP service on a remote device. Once this command
has been sent, the device cannot make any other connection until the OPP connection is
disconnected.

Notes:
• If the remote slave device is not present or the service is not available, OPP NO
ANSWER will reply after the master connect timeout and you will have to try again.
• If security is enabled and the radio is connecting to a laptop that has not yet been
paired with it, the PAIRED,12345678912 message may return twice prior
to the OPP CONNECT.
• By default you will be located in the Bluetooth Exchange Folder of the remote device,
this will be the root directory.
• After making an OPP connection the radio will still be in command mode, not data
mode.
