Gyroscope and Visual Robot Vacuums

Sweeper SDK provides API requests and real-time channels to enable data queries.

• Historical records and other data can be queried or deleted by common API requests.
• The cleaning data transmitted from and to robot vacuums can be queried by the registration of listeners on real-time channels.

Record time 12 digits	Cleaning time 3 digits	Cleaning area 3 digits	subRecordId 5 digits	Example	Description
Yes	Yes	Yes	Yes	20200319202500300200123	The panel displays the timestamp when the record was reported by the MCU. Tap the record to show the map.
No	Yes	Yes	Yes	00300200123	The panel displays the timestamp when the record was reported to the cloud. Tap the record to show the map.
Yes	Yes	Yes	No	202003192025003002	The panel displays the timestamp when the record was reported by the MCU. Tap the record without showing the map.
No	Yes	Yes	No	003002	The panel displays the timestamp when the record was reported to the cloud. Tap the record without showing the map.

Real-time data channels

Data flow

Functional description

PBT gyroscope or visual robot vacuums transmit map data through streaming channels. The ThingSmartSweeperDeviceDelegate delegate protocol is implemented to receive the callback for received map streaming data.

Class name	Description
ThingSmartSweeperDevice	The class of PBT robot vacuums.

Subscribe to map streaming data

API description

Subscribes to map streaming data of a robot vacuum.

- (void)subscribeDeviceDataTransfer;

Example

ObjC:

- (void)subscribeDevice {

	[self.sweeperDevice subscribeDeviceDataTransfer];
}

Swift:

func subscribeDevice() {
	sweeperDevice?.subscribeDeviceDataTransfer()
}

Unsubscribe from map streaming data

API description

Unsubscribes from map streaming data of a robot vacuum.

- (void)unsubscribeDeviceDataTransfer;

Example

ObjC:

- (void)unsubscribeDevice {

	[self.sweeperDevice unsubscribeDeviceDataTransfer];
}

Swift:

func unsubscribeDevice() {
	sweeperDevice?.unsubscribeDeviceDataTransfer()
}

Execute a streaming data callback

API description

The callback to invoke when real-time streaming data is reported by a robot vacuum.

- (void)sweeperDevice:(ThingSmartSweeperDevice *)sweeperDevice didReceiveStreamData:(NSData *)data;

Parameters

Parameter	Description
sweeperDevice	The instance object of ThingSmartSweeperDevice.
data	The streaming data of NSData type. ~Bits 0 to 3 indicate subRecordId of a map, and ~bits 4 to 12 are not business data and will neither be parsed. Note that actual map data is indicated starting from Bit 13. Every three bits create a map point, including the x-coordinate, y-coordinate, and point type of the map point.

Example

ObjC:

self.sweeperDevice = [ThingSmartSweeperDevice deviceWithDeviceId:<#devId#>];
self.sweeperDevice.delegate = self;

// Implements the delegate method.
- (void)sweeperDevice:(ThingSmartSweeperDevice *)sweeperDevice didReceiveStreamData:(NSData *)data {

}

Swift:

sweeperDevice = ThingSmartSweeperDevice.init(deviceId: "your_devId")
sweeperDevice?.delegate = self

func sweeperDevice(_ sweeperDevice: ThingSmartSweeperDevice, didReceiveStreamData data: Data) {

}
