5 All commands are used via debugfs interface.
7 Set/get driver configurations
8 =============================
10 Path: /debug/btmrvl/config/
13 These commands are used to configure the host sleep parameters::
17 where GPIO is the pin number of GPIO used to wake up the host.
18 It could be any valid GPIO pin# (e.g. 0-7) or 0xff (SDIO interface
19 wakeup will be used instead).
21 where Gap is the gap in milli seconds between wakeup signal and
22 wakeup event, or 0xff for special host sleep setting.
26 # Use SDIO interface to wake up the host and set GAP to 0x80:
27 echo 0xff80 > /debug/btmrvl/config/gpiogap
28 echo 1 > /debug/btmrvl/config/hscfgcmd
30 # Use GPIO pin #3 to wake up the host and set GAP to 0xff:
31 echo 0x03ff > /debug/btmrvl/config/gpiogap
32 echo 1 > /debug/btmrvl/config/hscfgcmd
35 These commands are used to enable/disable auto sleep mode
39 1 -- Enable auto sleep mode
40 0 -- Disable auto sleep mode
44 # Enable auto sleep mode
45 echo 1 > /debug/btmrvl/config/psmode
46 echo 1 > /debug/btmrvl/config/pscmd
48 # Disable auto sleep mode
49 echo 0 > /debug/btmrvl/config/psmode
50 echo 1 > /debug/btmrvl/config/pscmd
54 These commands are used to enable host sleep or wake up firmware
58 1 -- Enable host sleep
64 echo 1 > /debug/btmrvl/config/hsmode
65 echo 1 > /debug/btmrvl/config/hscmd
68 echo 0 > /debug/btmrvl/config/hsmode
69 echo 1 > /debug/btmrvl/config/hscmd
75 Path: /debug/btmrvl/status/
79 cat /debug/btmrvl/status/<args>
84 This command displays current auto sleep status.
87 This command display the power save state.
90 This command display the host sleep state.
93 This command displays the value of Tx download ready flag.
95 Issuing a raw hci command
96 =========================
98 Use hcitool to issue raw hci command, refer to hcitool manual
102 Hcitool cmd <ogf> <ocf> [Parameters]
104 Interface Control Command::
106 hcitool cmd 0x3f 0x5b 0xf5 0x01 0x00 --Enable All interface
107 hcitool cmd 0x3f 0x5b 0xf5 0x01 0x01 --Enable Wlan interface
108 hcitool cmd 0x3f 0x5b 0xf5 0x01 0x02 --Enable BT interface
109 hcitool cmd 0x3f 0x5b 0xf5 0x00 0x00 --Disable All interface
110 hcitool cmd 0x3f 0x5b 0xf5 0x00 0x01 --Disable Wlan interface
111 hcitool cmd 0x3f 0x5b 0xf5 0x00 0x02 --Disable BT interface
