FogCloud YAT Product Access Protocol

1. Description

• The identification code of the Fog platform is: 0x10
• When connecting modules to the Fog platform, it is necessary to burn triplets using a one machine, one code method.
• Triples can be burned by Qingke or by customers themselves.

2. Product Configuration Format

• pk: ProductKey

• ps: ProductSecret

• dn: DeviceName

• ds: DeviceSecret

  { "pk": "123", "ps": "456", "dn": "asd", "ds": "zxc", }

3. Network Configuration

Fog platform distribution method: Bluetooth distribution network.

The format is as follows: MCU->WiFi

CMD	PAYLOAD
	Cloud Code	Type	TimeOut	Description
0x13	0x00	0x00	2 Byte	EMC Series: Bluetooth distribution network
	0x10	0x00	2 Byte	EMC Series: Bluetooth distribution network
		0x03	2 Byte	Bluetooth distribution network

4. JSON for Data Communication

If you choose to use JSON format as the attribute communication method between MCU and WiFi module for data communication, as the Fog platform data is divided into attributes, events, and services, MCU needs to distinguish data types.

Note: JSON is provided based on actual product functions

4.1. Attribute Reporting

MCU->WiFi

CMD	PAYLOAD		Description
	Type	JSON	JSONformat data n value range from 1 ~1023
0x27	0x01	n Byte	Attribute Reporting

WiFi->MCU None

4.2. Attribute Distribution

WiFi->MCU

CMD	PAYLOAD		Description
	Type	JSON	JSONformat data n value range from 1 ~1023
0x27	0x01	n Byte	Attribute distribution

MCU->WiFi None The format of attribute distribution is consistent with that of Attribute Reporting

4.3. Event Reporting

MCU->WiFi

CMD	PAYLOAD				Description
	Type	EventID Length	EventID	JSON	JSONformat data nvalue range from 1~1020
0x27	0x02	1 Byte	n Byte	n Byte

EventID Length: Length of event ID EventID：event ID，string type WiFi->MCU None

4.4. Service Distribution

WiFi->MCU

CMD	PAYLOAD				Description
	Type	ServiceID Len	ServiceID	JSON	JSONformat data n value range from 1 ~1023
0x27	0x03	1 Byte	n Byte	n Byte	Service Distribution

ServiceID Len: length of service ID serviceID：service ID，string type MCU->WiFi None

5. Data Communication of RAW-TLV

5.1. Attribute Configuration Table Rules

The attribute configuration table of RAW-TLV mode is stored in the cloud.

Script:

Modify the profile, replace the profile in fog.js, and upload it to the Fog backend.

Note: TLV is provided based on actual product attributes and functions.

6. Cli

Switch Environment：

fog_env <env>(0:product, 1:dev, 2:beta)

Triple Burning：

fog keys. fogke [<fog_pk> <fog_ps>&lt;fog_dn&gt;&lt;fog_ds&gt;]

Private Domain Name Settings：

fog_private_domain eu-dev.fogcloud.io eu-dev.fogcloud.io
