Operation and Use

Bluetooth Connection

Step 1.
Connect the USB cable to power the M7. The PWR indicator remains solid red, while the BT/LoRa indicator flashes blue slowly for 30 seconds and then turns off, indicating that the device has entered Bluetooth pairing mode

Step 2. Download the Meshtastic App

Step 3. Turn on Bluetooth on your phone, open the Meshtastic app, tap the icon in the lower-right corner, select the Bluetooth name corresponding to your device, and tap it to connect. Enter the password 123456, then tap “OK.” The BT/LoRa indicator remains solid blue for 30 seconds and then turns off, indicating that the Bluetooth connection has been established successfully.
(The Bluetooth name is generated by reversing the first four characters of the MAC address. For example, if the first four characters of the MAC address are AB:CD, the last four characters of the Bluetooth name will be CD:AB.)

Step 4.
Enter the Settings interface and tap “LoRa” to configure the parameters.

Step 5.
Select “Region” and “Frequency Override” according to the actual requirements.
In this example, EU868 is selected. Set “Transmit Power” to 22, leave the other settings at their default values, and tap “Save”, followed by “Close.” Wait for the device to restart. Once it has restarted, the Meshtastic app will automatically connect to the device via Bluetooth.

Step 6.
Go to the Settings page and tap “Channels” to create a channel.

Step 7.
Tap “Create Channel”, customize the “Channel Name” and “PSK” fields, then tap “Save” followed by “Close.” The channel has been created successfully.

Step 8.
Tap the button shown in the figure, locate the channel you just created, and tap to enter it. Repeat the steps above on the other M7 device. The two devices will then be able to send messages to each other.\

Wi-Fi Connection

Troubleshooting

• Device can’t join the Meshtastic network: Ensure Region, frequency band, encryption key (PSK), and other parameters match the other nodes.
• Device detects other nodes but can’t communicate: Check that the antenna is connected correctly and confirm the devices are within effective communication range. Verify the network configuration.
• Changes don’t take effect after modifying parameters: Make sure settings were saved and synchronized. Some settings require a device restart. If it still fails, restore default settings and configure again.
• Device can’t power on: Confirm correct power connection and that the power source meets the product requirements. Disconnect and reconnect power; if it still won’t start, contact after-sales service.
• How to connect through Ethernet: Use an Ethernet cable to connect the device to the local network, and ensure the device and your configuration terminal are on the same network. If it fails, check the cable, network equipment, and IP address configuration.
