blatann.gap.scanning module¶
- class blatann.gap.scanning.ScanParameters(interval_ms, window_ms, timeout_s, active=True)¶
Bases:
BLEGapScanParams
Class which holds scanning parameters
- validate()¶
- update(window_ms, interval_ms, timeout_s, active)¶
- class blatann.gap.scanning.Scanner(ble_device)¶
Bases:
object
- property on_scan_received: Event[Scanner, ScanReport]¶
Event that is raised whenever a scan report is received
- property on_scan_timeout: Event[Scanner, ScanReportCollection]¶
Event that is raised when scanning completes/times out
- set_default_scan_params(interval_ms=200, window_ms=150, timeout_seconds=10, active_scanning=True)¶
Sets the default scan parameters so they do not have to be specified each time a scan is started. Reference the Bluetooth specification for valid ranges for parameters.
- Parameters
interval_ms (
float
) – The interval which to scan for advertising packets, in millisecondswindow_ms (
float
) – How long within a single scan interval to be actively listening for advertising packets, in millisecondstimeout_seconds (
int
) – How long to advertise for, in secondsactive_scanning (
bool
) – Whether or not to fetch scan response packets from advertisers
- start_scan(scan_parameters=None, clear_scan_reports=True)¶
Starts a scan and returns a waitable for when the scan completes
- Parameters
scan_parameters (
Optional
[ScanParameters
]) – Optional scan parameters. Uses default if not specifiedclear_scan_reports – Flag to clear out previous scan reports
- Return type
- Returns
A Waitable which will trigger once the scan finishes based on the timeout specified. Waitable returns a ScanReportCollection of the advertising packets found
- stop()¶
Stops scanning
