IP Video Door Bell - Atz-dbv01p

[riogrande75]

It's me once again: I managed to get pictures from the lower side of the PCB.
Here the pinout that works for me
I use a cheap chinese USB-UART converter with 3.3v levels, baudrate 115200.

Thanks riogrande75, can you make a backup with all the files and upload it to some places? probably there is some hidden services for the functions that we are looking for.

Thanks

[riogrande75]

probably there is some hidden services for the functions that we are looking for

No, I am sure this is not the case. The files are just the already known 5 partitions:
mtdblock0: uboot (bootloader)
mtdblock1: boot (kernel,read-only)
mtdblock2: rootfs (/,linux,read-only)
mtdblock3: rom (/rom,some settigs, certificates,etc.)
mtdblock4: npc (/npc,the doorbell application itself)
I analyzed it and so far, I guess we get not arround the npc programm. Without it running, the camera,etc. is not responsible. Anyhow, if I kill the npc task the device reboots immediately (a watchdog supervises this program).

can you make a backup with all the files and upload it to some places

I could upload the files - but it will not show anything new to us. The rootfs is a simple linux for SoC, read-only, but there are some good usable functions like telnetd and tftp on it. They just need to be started.
/rom and /npc is actually just the 2 partitions that you get when you split the fw file (npcupg_13.00.01.10.bin). This partitions are writeable and cross-compiled programms (the link I posted works for me) can get installed there. I managed to write a program in c (I am not a programmer!) that sends a UDP message to a server already. As soon as I found a way to catch the doorbell button (either via filering stdout or directly polling gpio) I guess, a little program fulfils our wish
All we need is a guy with a little more programming abitilities than me

Thanks riogrande75 for figuring out the console. I have a slightly different version of the doorbell but was able to connect to the console as in the following image.

The console produces the following output on startup.

It would seem if we wright a program/script to parse the console output looking for "push : Some Body visit!" we would have the trigger to send a UDP message. http://www.linux.it/~rubini/docs/sercons/sercons.htm has an example program that may be useful.

I am intending to set up a development environment when I get some spare time and see how we go!

[riogrande75]

Cool. The posted output is pretty identical to my ATZ-DBV03p. So sw seems to be the same.
I managed to write a program to send a simple UDP message already - tested on the doorbell. Works fine.
So far I could not grab the output on the console with a c prog. I tried different functions (fget,fopen,popen,...) on /dev/console and /dev/ttyAMA0 - but somehow it's a bit different to other linux systems I know so far.
Maybe we need to catch the output of the running npc task (this task produces the output). If this still does not work, someone needs to have a look at the gpio's. From the SDK from HiSilicon I got compiled "i2c_read" and "i2c_write" commands, but gpio's are polled somehow different to a RPi.

[riogrande75]

Finally i found some time to play again with the doorbell. And I made some progress: I have now a tiny c-program, that sends a udp message including "YOU HAVE A VISITOR WAITING!" to a defined server as soon as the doorbell button was pressed.
All you have to do is getting telnet access to the doorbell (see above: "telnetd" at the console / putty), copy my program (either via tftp or manully on your pc) to the sd-card run it.
Anyone who's interrested just pm me for the code or a specific binary for your environment.

[papoo]

you have a PM

[jumble]

Hey Riogrande75, if you could you post the c source code here or PM me with the code that would be great. Thx

[riogrande75]

Hi!
I just uploaded my code so far to github.com/riogrande75/doorbell/.
As mentioned, it's hardly "work-in-progress". Feel free to improve it.

[riogrande75]

I changed my idea of polling directories for alarm pictures, which gets by far to complex.
Now I just redirect the log output of PID 751 (npc) into a logfile, grep the doorbell event an send a UDP message to my server.

Code: Select all

#!/bin/sh
telnetd &
ifconfig wlan0 down
cd /mnt/disc1
./reredirect -m npc.log 791
LOGFILE=/mnt/disc1/npc.log
tail -f $LOGFILE| while read LINE; do
        echo $LINE| grep -q "vDoorBellEventProc" | ./sendudp
done
exit 0

All you need is "reredirect" https://github.com/jerome-pouiller/reredirect and sendudp https://github.com/riogrande75/doorbell ... /sendudp.c crosscompiled and this shell script.
Working binaries via PM.

[riogrande75]

I don't know if there are still interrested owners arround, but I wanted to let you know that I implemented a MQTT client (PUB/SUB) into the doorbell.
Also it's quite easy to run telnetd and so on at startup: just rename the main application "/npc/npc" to e.g. "/npc/npc-exe" and insert a shell script as "/npc/npc" (and change file-rights accordingly). Let the script start telnetd, npc-exe and the mqtt client and you're ready to install the bell.
Due the fact, the /npc partition is writeable, all the settings are rebootsafe and then UART cables can be removed then.

Salut riogrande75,
Bravo pour le boulot fait !
Pour installer ton petit client, il faut bidouiller l'uart en ouvrant le portier ?

Hi riogrande75,
my compliments for your great work,
with your info now i can have acces to my atz-dbv03p.
Can you please send me the mqtt client.
Thanks, fulvio.

oui!

You got PM!

Some new findings from my side:
Until now, I was not able to access gpio's directly to poll doorbell button or switch relay for dooropener.
Some googeling brought up the gpio memory addresses of Hi3518 chip.
So I tested it out and found the address of the doorbell button gpio pin:

Code: Select all

# devmem 0x200f011c
0x00000000
# devmem 0x200f011c w 1

First command shows register of doorbell button (usually 0x0). When you put (write) a 1 in there (2nd command), the npc app recognizes a doorbell press.
I did not find the dooropener register yet, but I will not give up.
Nevertheless, I found a way to open the dooropener relay remotely without using the could application:
With the mentioned IPC-TEST-TOOL you can localy (inside you LAN) test the doorbell functions. There is also a "unlock" button which let's the relay switch.

So I sniffered the UDP message from the PC running the tool to the doorbell. Then I sent the same UDP message with a "Packet Sender" to the doorbells IP and ... The relay switches!!! lol
It does not make sense to post my UDP packet here, due the fact, its encrypted and the ID and password is different to other bells. But it's quite easy to capture.
Feel free to ask me, if any help is needed.

Hi riogrande75,
Do you think it could be possible to monitore the button status via http commands ?
If so I would try to implement it into Jeedom domotic solution.

The only one feature that i need is open the door calling some HTTP service, or sending some TCP packet, etc ...

This can now be achived with a simple UDP packet to the doorbell.
I am sure this function is available in almost all programming languages.

Hi riogrande75,
Could you send me by MP the UDP packet to use ?

Monitoring the button with http is not a good idea. Anyhow it could be done, if you write a C-programm that answers the http requests.
My opinion is, it's better to send a specific HTTP POST from the device to a specified server. This can be done already when you read my last posts.

I am currently working on programm, that checks the doorbell button internaly (via monitoring the gpio memory) and sends a MQTT publish to a specified server. I am already close to the final solution - but my c programming abitilities are not very good and programms for this device need to be written in c (and crosscompiled). So any help is appreciated

If you want any programm to run on the doorbell, just sent me the c sourcecode - I will send you a running binary.
