Erel B4X founder Staff member Licensed User Longtime User Mar 9, 2025 #6 V1.01 - Bleak.Is_Scanning property. This property is useful to avoid handling DeviceFound events after calling StopScan (which isn't an immediate action). Code: Private Sub BLE_DeviceFound (Device As BleakDevice) If BLE.IsScanning = False Then Return
