Reolink Argus pro - get and set PIR status

[jbremond]

Hello,

I am starting to implement a new neolink command line to GET and SET the PIR status of the reolink argus pro camera (this should work also for reolnk argus 2).

After using the wireshark dissector and using the app in parallel, I now know the the message ID is:

• 212 to get the PIR motion status
• 213 to set the PIR motion (enable or disable)

What I don't know is the XML schema to use for this.
Do you know the procedure to print the RAW XML from the code for example ? or to decode it from wireshark ?

In the code, I do print but after XML parsing:

let get = Bc {
            meta: BcMeta {
                msg_id: MSG_ID_GET_MOTION_ALARM,
                channel_id: self.channel_id,
                msg_num: self.new_message_num(),
                response_code: 0,
                stream_type: 0,
                class: 0x6414,
            },
            body: BcBody::ModernMsg(ModernMsg {
                extension: Some(Extension {
                    channel_id: Some(self.channel_id),
                    ..Default::default()
                }),
                payload: None,
            }),
        };

        sub_get.send(get)?;
        let msg = sub_get.rx.recv_timeout(RX_TIMEOUT)?;

        println!("{:?}", msg.body);

So it does not print the RAW XML

Thank you for your help !

It is not in xml yet. At this stage it is still generic data. It is only encoded into xml just before sending the message.

If you want to see where it is done then you should check out here: neolink/crates/core/src/bc/ser.rs

neolink/crates/core/src/bc/ser.rs

Lines 80 to 88 in 57c55e4

	fn bc_ext<W: Write>(
	enc_offset: u32,
	xml: &Extension,
	encryption_protocol: &EncryptionProtocol,
	) -> impl SerializeFn<W> {
	let xml_bytes = xml.serialize(vec![]).unwrap();
	let enc_bytes = xml_crypto::encrypt(enc_offset, &xml_bytes, encryption_protocol);
	slice(enc_bytes)
	}

In fact, what I would like to have, is to know the body content as raw text in the response message coming from the camera.
I don't know what field I will have with this new message>
Then, with this information, I can write new fields into the XML serializer to support these new messages (and XML serialization).

Ah you need to decode the xml from the Reolink app really not from neolink.

My recommendation is:

1. Get an older version of the official desktop app (prior to the inclusion of their aes)
2. Install that on your computer that has wireshark
3. Connect with with that official app to the camera and watch the messages from wireshark.

The older client uses an older encryption that is easily broken in wireshark using our dissector. You can then view the official xml in wireshark.

[jbremond]

Do you have an idea of the "old version" ? https://support.reolink.com/hc/en-us/articles/360012466173-All-Reolink-Client-Versions
for example: V7.2.2.33 ?

Then, the wireshark dissector will automatically decode the body ? Or do I need to do something else ?

[jbremond]

I mange to find an old version of reolink app without AES here: https://s3.amazonaws.com/reolink-storage/website/client/Reolink+Client+Windows+v7.2.2.33+x64.zip

I managed, with an old version of reolink app, to get the XML and message type, when setting PIR to on:

With this, I will try to use it within a new neolink command
