118 = 2. Configure PF52 to connect to LoRaWAN network =
119
120 == 2.1 How it works ==
121
122
123 The PF52 is configured as **LoRaWAN OTAA Class A** mode by default. It has OTAA keys to join LoRaWAN network. To connect a local LoRaWAN network, you need to input the OTAA keys in the LoRaWAN IoT server and press the button to activate thePF52. It will automatically join the network via OTAA and start to send the sensor value. The default uplink interval is 20 minutes.
124
125 The LED light is at the upper left for a positive viewing angle.When the character crosses the horizontal line in the middle, the count increases by one.
126
127 For details, please see the case.

387 To better manage and monitor PF52 devices, users can remotely control and manage the devices by downloading a specially designed mobile application.
388
389 Once the application is installed, the next step is to establish a Bluetooth connection between your smart device and PF52.
390
391 Please make sure that the Bluetooth function of your mobile phone is turned on and within the search range of the device (usually within 10 meters).
392
393 After opening the application, follow the on-screen prompts to complete the simple pairing process.
394
395 After a successful connection, the application will automatically detect the PF52 and start synchronizing the device status.
396
397 Once the connection is established, users can obtain high-definition real-time images captured by PF52 through the application.
