hcsecd.confhcsecd(8) configuration file



The hcsecd.conf file is the configuration file for the hcsecd(8) Bluetooth link keys/PIN codes management daemon.

The hcsecd.conf file is a free-form ASCII text file. It is parsed by the recursive-descent parser built into hcsecd(8). The file may contain extra tabs and newlines for formatting purposes. Keywords in the file are case-sensitive. Comments may be placed anywhere within the file (except within quotes). Comments begin with the ‘#’ character and end at the end of the line.


The hcsecd.conf file consists of a list of device entries. Each device entry defines a link key or PIN code for a remote Bluetooth device. Each remote Bluetooth device is identified by its unique BD_ADDR.

The device entry

device { option argument; [ option argument; ] }

The following section describes all supported options and arguments.
bdaddr BD_ADDR
  Specify remote device BD_ADDR for the entry.
name device_name
  Specify user friendly name for the entry. Name is a string in straight double quotes.
key link_key
  Specify link key for the entry. Link key is hexadecimal string up to 32 characters in length starting with ‘0x’.

  Specify no link key for the entry.
pin PIN_code

pin nopin
  Specify no PIN code for the entry.


A sample hcsecd.conf file:
# Default entry is applied if no better match found
# It MUST have 00:00:00:00:00:00 as bdaddr
device {
        bdaddr  00:00:00:00:00:00;
        name    "Default entry";
        key     nokey;
        pin     nopin;

# Ericsson T68 phone device { bdaddr 00:80:37:5e:4d:d4; name "Ericsson T68 phone"; key nokey; pin "0000"; # PIN code }

# Dummy device device { bdaddr 00:11:22:33:44:55; name "Dummy"; key 0x00112233445566778899aabbccddeeff; # 16 bytes key pin nopin; }
