This automation will be triggered when a Bluetooth advertising is received. This works with continuous set to true or false.ĮSP32 Bluetooth Low Energy Tracker Automation ¶ on_ble_advertise Trigger ¶ On_scan_end ( Optional, Automation): An automation to perform whenĪ BLE scan has completed (the duration of the scan). Perform when a Bluetooth advertising with service data is received. On_ble_service_data_advertise ( Optional, Automation): An automation to On_ble_manufacturer_data_advertise Trigger. Perform when a Bluetooth advertising with manufacturer data is received. On_ble_manufacturer_data_advertise ( Optional, Automation): An automation to When a Bluetooth advertising is received. On_ble_advertise ( Optional, Automation): An automation to perform Id ( Optional, ID): Manually specify the ID for this ESP32 BLE Hub. Defaults to true.Ĭontinuous ( Optional, boolean): Whether to scan continuously (forever) or to only scan whenĪsked to start a scan (with start_scan action). You can save power and RF pollution by setting it to false. Some devices don’t need this, in that case
With some devices this is necessary to receive all data,īut also drains those devices’ power a bit more. Defaults to 5min.Īctive ( Optional, boolean): Whether to actively send scan requests to request more dataĪfter having received an advertising packet.
Impact on the device but can be used to debug the BLE stack. Defaults to 30msĭuration ( Optional, Time): The duration of each complete scan. Spend more time listening to packets (but also consume more power). If this is close to the interval value, the ESP will Window ( Optional, Time): The time the ESP is actively listening for packets This is the time the ESP spends on each of the 3 BLE advertising channels. Interval ( Optional, Time): The interval between each consecutive scan window. Scan_parameters ( Optional): Advanced parameters for configuring the scan behavior of the ESP32. Please flash the ESP32 via USB when adding this to your configuration.

If there is still something you don't understand, you can comment down below.The first time this component is enabled for an ESP32, the code partition needs to be Once the Slave HC-05 receives the character "b," it turns on the LED, and when you take your finger off the button, there is no data being sent to the HC-05, so the LED turns off. The way this works is, for example, when you press the button on Arduino A, the Arduino boards send the character "b" to the Master HC-05, which then over Bluetooth sends the character to the Slave HC-05.
When you press the Button on Arduino B, the LED on Arduino A turns on, and when you take your finger off, the LED turns off. The same happens to the LED on Arduino A. If you now press the button on Arduino A, the LED on Arduino B will turn on, and when you take your finger off the button, the LED will turn off. As displayed in the image above, for ease of understanding, we will name one of the Arduino boards "Arduino A" to which the Master HC-05 will connect and the other Arduino board "Arduino B" to which the Slave HC-05 will connect. The LED on the HC-05 modules will blink slowly until they have paired. To test if the project is working properly, plug both Arduino boards into a power source.
