蓝牙：Call Control Profile Shell

呼叫控制服务器

呼叫控制服务器是一种角色，通常位于能够发起呼叫的设备上，包括来自 Skype 等应用的呼叫，例如（智能）手机和 PC，这些设备通常是 GAP 中心设备。

使用呼叫控制服务器

服务器可以在本地控制，也可以由远端设备控制（在通话中时）。例如，远端设备可以向服务器发起呼叫，服务器也可以在没有客户端的情况下向远端设备发起呼叫。

对于所有接受可选 index 的命令，如果未提供索引，则默认为 0，即 GTBS 承载。

ccp_call_control_server --help
ccp_call_control_server - Bluetooth CCP Call Control Server shell commands
Subcommands:
  init                    : Initialize CCP Call Control Server
  set_bearer_name         : Set bearer name [index] <name>
  get_bearer_name         : Get bearer name [index]
  get_bearer_uci          : Get bearer UCI [index]
  set_bearer_tech         : Set bearer technology [index] <technology>
  get_bearer_tech         : Get bearer technology [index]
  set_bearer_uri_schemes  : Set bearer URI schemes supported list [index] <URI schemes>
                           (e.g. "tel,skype")
  get_bearer_uri_schemes  : Get bearer URI schemes supported list [index]

用法示例

设置

uart:~$ bt init
uart:~$ ccp_call_control_server init
Registered GTBS bearer
Registered bearer[1]
uart:~$ bt connect P:xx:xx:xx:xx:xx:xx

设置和获取承载名称

uart:~$ ccp_call_control_server get_bearer_name
Bearer[0] name: Generic TBS
uart:~$ ccp_call_control_server set_bearer_name "New name"
Bearer[0] name: New name
uart:~$ ccp_call_control_server get_bearer_name
Bearer[0] name: New name
uart:~$ ccp_call_control_server get_bearer_name 1
Bearer[1] name: Telephone Bearer #1
uart:~$ ccp_call_control_server set_bearer_name 1 "New TBS name"
Bearer[1] name: New TBS name
uart:~$ ccp_call_control_server get_bearer_name 1
Bearer[1] name: New TBS name

获取承载 UCI

uart:~$ ccp_call_control_server get_bearer_uci
Bearer[0] UCI: un999
uart:~$ ccp_call_control_server get_bearer_uci 1
Bearer[1] UCI: skype

设置和获取承载技术

uart:~$ ccp_call_control_server get_bearer_tech
Bearer[0] technology: 3G (0x01)
uart:~$ ccp_call_control_server set_bearer_tech 0x02
Bearer[0] new technology: 4G (0x02)

设置和获取承载 URI 支持的方案列表

uart:~$ ccp_call_control_server get_bearer_uri_schemes
Bearer[0] URI schemes supported list: tel,skype
uart:~$ ccp_call_control_server set_bearer_uri_schemes "tel,teamspeak"
Bearer[0] new URI schemes supported list: tel,teamspeak

呼叫控制客户端

呼叫控制客户端是一种角色，通常位于耳塞或耳机等资源受限设备上。

使用呼叫控制客户端

客户端可以控制远端 CCP 服务器设备。例如，远端设备可能有来电，客户端可以接听。

uart:~$ ccp_call_control_client --help
ccp_call_control_client - Bluetooth CCP Call Control Client shell commands
Subcommands:
  discover  : Discover GTBS and TBS on remote device

连接后的用法示例

uart:~$ ccp_call_control_client discover
Discovery completed with GTBS and 1 TBS bearers

uart:~$ ccp_call_control_client read_bearer_name
Bearer 0x20046254 name: Generic TBS
uart:~$ ccp_call_control_client read_bearer_name 1
Bearer 0x20046256 name: Telephone Bearer #1
uart:~$ ccp_call_control_client read_bearer_uci
Bearer 0x20046254 UCI: un999
uart:~$ ccp_call_control_client read_bearer_uci 1
Bearer 0x20046256 UCI: skype
