= Using Bluetooth from the command line = == pand == The daemon responsible for Personal Area Networks. Example: Set infrastructure mode: node1-1 as the master and node1-2 as the slave: {{{ node1-1:~# pand --listen -role NAP --master --autozap }}} wait for at least 10 seconds for the interface to configure {{{ node1-2:~# pand --connect 00:0A:3A:53:D4:82 --service NAP --autozap }}} Again, wait for at least 10 seconds to establish the link. Then set IP addreses: {{{ node1-1:~# ifconfig bnep0 192.168.1.1 }}} {{{ node1-2:~# ifconfig bnep0 192.168.1.2 node1-2:~# ping 192.168.1.1 PING 192.168.1.1 (192.168.1.1): 56 data bytes 64 bytes from 192.168.1.1: icmp_seq=0 ttl=64 time=74.9 ms 64 bytes from 192.168.1.1: icmp_seq=1 ttl=64 time=39.6 ms }}} == hciconfig and hcitool == ''hciconfig'' returns current status of the ''device'' or configures it: {{{ root@node1-1:~# hciconfig hci0 hci0: Type: USB BD Address: 00:0A:3A:59:9A:34 ACL MTU: 192:8 SCO MTU: 64:8 UP RUNNING PSCAN RX bytes:409 acl:0 sco:0 events:18 errors:0 TX bytes:316 acl:0 sco:0 commands:17 errors:0 }}} ''hcitool'' configures Bluetooth ''connections''.
