Operation Guide

NFC Configuration
EM300 series can be configured via NFC.

1. Download and install the “Milesight ToolBox” App from Google Play or Apple Store.
2. Enable NFC on the smartphone and open the “Milesight ToolBox” App.
3. Attach the smartphone with NFC area to the device to read basic information.
4. Basic information and settings of devices will be shown on ToolBox if it’s recognized successfully. You can turn on/off the device by tapping the button on the Device Status. In order to protect the security of devices, password validation is required when configuring via unused phone. The default password is 123456.
5. Tap the “Read” button to check the current status and sensor data of the device.
6. Tap the “Write” button to write all your settings to the device.

Note:

1. Ensure the location of the smartphone NFC area and it’s recommended to take off the phone case.
2. If the smartphone fails to read/write configurations via NFC, keep the phone away and back to try again.
3. EM300 series can also be configured by a dedicated NFC reader provided by Milesight IoT or you can configure it via TTL interface inside the device.

LoRaWAN Settings
LoRaWAN settings is used for configuring the transmission parameters in LoRaWAN® network.

Basic LoRaWAN Settings:
Go to Device- >Setting->LoRaWAN Settings of ToolBox App to configure join type, App EUI, App Key and other information. You can also keep all settings by default.

Spread Factor| If ADR is disabled, the device will send data via this spread factor.

Confirmed Mode

| If the device does not receive ACK packet from network server, it will resend data 3 times at most.

Rejoin Mode

| Reporting interval ≤ 30 mins: device will send specific mounts of LoRaMAC packets to check connection status every 30 mins; If no reply after specific packets, the device will re-join.

Reporting interval > 30 mins: the device will send specific mounts of LoRaMAC packets every to check the connection status every reporting interval; If no reply

after specific packets, the device will re-join.

ADR Mode| Allow the network server to adjust data rate of the device.
Tx Power| Transmit power of device.

Note:

1. Please contact sales for device EUI list if there are many units.
2. Please contact sales if you need random App keys before purchase.
3. Select OTAA mode if you use Milesight IoT cloud to manage devices.
4. Only OTAA mode supports rejoin mode.

LoRaWAN Frequency Settings:
Go to Setting- >LoRaWAN Settings of ToolBox App to select supported frequency and select channels to send uplinks. Make sure the channels match the LoRaWAN® gateway.

If frequency is one of CN470/AU915/US915, you can enter the index of the channel that you want to enable in the input box, making them separated by commas.

Examples:

1, 40: Enabling Channel 1 and Channel 40
1-40: Enabling Channel 1 to Channel 40
