Ir codes for Android 9 - Redwid - 07-05-2020

Is there any way to get IR codes on Android images.
Any drivers, tools ... etc presents there?
Grep shows something related irc and lirc:


Code:
./proc/kallsyms:0000000000000000 t nf_conntrack_irc_fini ./proc/kallsyms:0000000000000000 R __ksymtab_nf_nat_irc_hook ./proc/kallsyms:0000000000000000 r __kcrctab_nf_nat_irc_hook ./proc/kallsyms:0000000000000000 r __kstrtab_nf_nat_irc_hook ./proc/kallsyms:0000000000000000 t init_rc_map_lirc ./proc/kallsyms:0000000000000000 t nf_conntrack_irc_init ./proc/kallsyms:0000000000000000 t nf_nat_irc_init ./proc/kallsyms:0000000000000000 t exit_rc_map_lirc ./proc/kallsyms:0000000000000000 t nf_nat_irc_fini ./proc/kallsyms:0000000000000000 t __initcall_init_rc_map_lirc6 ./proc/kallsyms:0000000000000000 t __initcall_nf_conntrack_irc_init6 ./proc/kallsyms:0000000000000000 t __initcall_nf_nat_irc_init6 ./proc/kallsyms:0000000000000000 D nf_nat_irc_hook ./proc/kallsyms:0000000000000000 d irc ./proc/kallsyms:0000000000000000 d lirc_map ./proc/kallsyms:0000000000000000 b lirc ./proc/kallsyms:0000000000000000 b irc_buffer_lock ./proc/kallsyms:0000000000000000 b irc_buffer ./proc/kallsyms:0000000000000000 b irc_exp_policy

A little bit more info about device:





Code:
getevent -lp /dev/input/event0 add device 1: /dev/input/event0   name:    "ff1b0030.pwm"   events:     KEY (0001): KEY_1                KEY_2                KEY_3                KEY_4                                KEY_5                KEY_6                KEY_7                KEY_8                                KEY_9                KEY_0                KEY_BACKSPACE        KEY_HOME                            KEY_UP                KEY_LEFT              KEY_RIGHT            KEY_DOWN                            KEY_DELETE            KEY_MUTE              KEY_VOLUMEDOWN        KEY_VOLUMEUP                        KEY_POWER            KEY_MENU              KEY_SETUP            KEY_WAKEUP                          KEY_BACK              KEY_PLAYPAUSE        KEY_F13              KEY_F14                              KEY_F15              KEY_F16              KEY_SEARCH            KEY_REPLY                            KEY_TEXT              KEY_BLUE              KEY_CHANNELUP          input props:     <none>


+ this:

Somehow this codes should be mapped to this remote?

Found more info.
About ir driver: http://wiki.t-firefly.com/en/AIO-3399C/driver_ir.html
Source code of that driver:
https://gitlab.com/TeeFirefly/px3se-buildroot/blob/firefly-px3se/kernel/drivers/input/remotectl/rockchip_pwm_remotectl.c
https://github.com/ayufan-rock64/android-kernel/blob/master/drivers/input/remotectl/rockchip_pwm_remotectl.c
Tool to get key info:

Chinese document regarding ir on rockchip:

I do have a device that could send any ir codes.
Doing a brute force right now.
Found that key codes:

0x404000FF or 0xFF -> KEY_0
0x404010EF -> KEY_8

RE: Ir codes for Android 9 - Redwid - 07-15-2020

Finally found this ir codes:

0x18E7; //KEY_VOLUMEUP
0xE817; //KEY_VOLUMEDOWN
0x58A7; //KEY_HOME
0xA25D; //KEY_BACK
0x08F7; //KEY_LEFT
0x8877; //KEY_RIGHT
0xFB04F; //KEY_REPLY <- not working
0xF807; //KEY_SEARCH
0x50AF; //KEY_MUTE
0xE21D; //KEY_TEXT
0xB24D; //KEY_POWER
0xD02F; //KEY_UP
0x708F; //KEY_DOWN
0x50AF; //KEY_MUTE
0x30CF; //KEY_DELETE
0xE00FF; //KEY_0
0x807F; //KEY_1
0x40BF; //KEY_2
0xE20DF; //KEY_4
0xA05F; //KEY_5
0x609F; //KEY_6
0x10EF; //KEY_8
0xE906F; //KEY_9

I've used this tool to find IR codes:
https://github.com/mdhiggins/ESP8266-HTTP-IR-Blaster

All codes in NEC 32 length format.
So sample curl to execute:
curl -X GET http://{your_device_ip}/msg?code=FF:NEC:32&simple=1

Unfortunately KEY_POWER ir code is unable to wake up device from power off state.
I've looked for home automation, so this is a kind of useless for me Sad
