Wi-Fi Networking

Wi-Fi Features

Wi-Fi Setup

Enable and Configure Wi-Fi Networking

The MV1C allows network settings to be viewed and changed using the keypad, without needing the calibration switch.

Keypad functions:

Note: Factory Network Settings: BLE ON/OFF = OFF, WIFI ON/OFF = OFF, dHCP_ON/OFF = ON.

To enable and configure Wi-Fi networking:

  1. With the MV1C ON and in Gross weight mode, press and hold the CLEAR key for approximately 3 seconds.
  2. The display will show SETUP REVIEW.
  3. Release the CLEAR key.
  4. The display will change to show the setup interface.
  5. Press the ID/HEIGHT key until BLE/WIFI is shown in the Menu area.
  6. Press the ENTER key. The display will show Redbird REV and the software version.
  7. Press the ENTER key. The display will show BLE ON/OFF and the current setting.
  8. Press the 1 (YES) key to select ON for BLE, then press ENTER.
  9. The display will change to show WIFI ON/OFF and the current setting.
  10. Press the 1 (YES) key to select ON for Wi-Fi, then press ENTER.
  11. The display will change to show DHCP ON/OFF and the current setting. Press ENTER to accept the current setting, or press 0 (NO) or 1 (YES) to change it, then press ENTER to save.

Note: Select OFF for a static IP address or ON for a dynamic IP address assigned by a DHCP server. Consult your network administrator.

If DHCP is set to OFF:

15. The display will prompt CLR WIFI CREd5. Press ENTER to accept the current setting, or press 0 (NO) to retain credentials or 1 (YES) to clear them, then press ENTER to save.

16. The display will change to show PRINTER TYPE. Press ENTER to accept the current setting, or press 0 (NO) or 1 (YES) to change it, then press ENTER to save.

Note: End of Print Linefeeds is not available for Redbird print type.

17. The display will change to show YEAR [YYYY].

18. Press the ID/HEIGHT key until the display returns to the normal weight display.

Configure Wi-Fi Network Module

When Wi-Fi credentials are not set, the Wi-Fi module enters listening mode as a Wi-Fi access point (SSID: “REDBIRD_WIFI_XX:XX”, where XX:XX is the last 4 digits of the MAC address). Connect to this AP using a Wi-Fi device (Smartphone, tablet, laptop). If connection fails, try moving the MV1C or power cycling it.

Once connected, open a web browser and go to redbird.com to access the “Configure Wi-Fi” page.

On the “Configure Wi-Fi” page, enter the Network Name (SSID), Password, and optionally, the Device Name. Click Connect. The module will store these credentials and connect automatically when turned on.

Changing the Network Credentials

To change network credentials:

  1. With the MV1C ON and in Gross weight mode, press and hold the CLEAR key for approximately 3 seconds.
  2. The display will show SETUP REVIEW.
  3. Release the CLEAR key.
  4. The display will change to show the setup interface.
  5. Press the ID/HEIGHT key until BLE/WIFI is shown in the Menu area.
  6. Press the ENTER key until the prompt CLR WIFI CREd5 is displayed.
  7. Press the 1 (YES) key and then ENTER to clear the network credentials.
  8. Press the ID/HEIGHT key until the display returns to the normal weight display.
  9. Repeat the steps in “Configure Wi-Fi Network Module” to set new credentials.

Wi-Fi Operation

Web Server

When connected to a network, the MV1C's hosted web page can be accessed via its IP address with “/webserver.html” appended. For example, if the IP address is “192.168.0.5”, navigate to 192.168.0.5/webserver.html to view weight, height, and BMI.

TCP/IP Connection

Continuous output is available via TCP/IP connection to the MV1C's IP address at port 10001.

SMA format for both commands:

<LF><r><n><m><f><XXXXXX.XXX><uuu><CR>

Where:

  • LF: Line feed (start of response).
  • s: Scale Status definition (Z=Zero, O=Over Capacity, U=Under Capacity, E=Zero Error, space=None).
  • r: Range (always “1” for single range).
  • n: Mode of Operation (G=Gross, T=Tare, N=Net).
  • m: Motion status (M=Scale in Motion, space=Scale not in Motion).
  • f: Future use.
  • XXXXXX.XXX: Weight with decimal point.
  • uuu: Units (e.g., lb, kg).
  • CR: Carriage Return (end of response).

SMA Commands: Once a TCP/IP connection is made, SMA commands can be issued. The MV1C responds according to the WI-FI AND BLUETOOTH SMA COMMANDS table.

Bluetooth Low Energy (BLE)

The MV1C can be enabled and configured for Bluetooth-capable devices using BLE. BLE standard specifications are used where possible. Custom services were created for indicator and scale information, with a communication protocol developed by the Scale Manufacturers Association (SMA).

Features Available via BLE

  • Device Information Service: Manufacturer Name, Model Number, Software Revision.
  • Battery Service: Battery Level Percentage.
  • Weight Scale Service: Weight Measurement, Weight Scale Feature.
  • Custom Services: Detecto SMA Service.

Enable Bluetooth (BLE) Networking

The MV1C allows Bluetooth settings to be viewed and changed using the keypad.

Keypad functions are the same as for Wi-Fi setup.

Note: Factory Network Settings: BLE ON/OFF = OFF, WIFI ON/OFF = OFF, dHCP ON/OFF = ON.

To enable Bluetooth (BLE) networking:

  1. With the MV1C ON and in Gross weight mode, press and hold the CLEAR key for approximately 3 seconds.
  2. The display will show SETUP REVIEW.
  3. Release the CLEAR key.
  4. The display will change to show the setup interface.
  5. Press the ID/HEIGHT key until BLE/WIFI is shown in the Menu area.
  6. With BLE/WIFI displayed, press the ENTER key. The display will show Redbird REV and the software version.
  7. Press the ENTER key. The display will show BLE ON/OFF and the current setting.
  8. Press the 1 (YES) key to select ON for BLE, then press ENTER.
  9. Press the ID/HEIGHT key until the display returns to the normal weight display. The MV1C is now ready to pair with a Bluetooth-capable device.

IMPORTANT! If attempting to turn off Bluetooth (BLE) while a device is connected, an error message ERR-BLE OFF will be displayed. The device must be disconnected, or the MV1C turned off and back on, before turning off Bluetooth (BLE).

Bluetooth Pairing

To pair a Bluetooth-capable device with the MV1C, select the MV1C's name (e.g., “MV Scale XX:XX:XX:XX:XX:XX”, where X's are the MAC address) from the list of available connections.

Note: If multiple MV1C's are nearby, press and hold the 0 (NO) key for about 5 seconds until Redbird REV and the software version are displayed. Release the 0 (NO) key. Press ENTER until BLE is shown in the Settings area with the Bluetooth advertisement data scrolling in the Menu area. Press ENTER when the display stops scrolling. The MV1C will return to the normal weight display.

When a stable reading is achieved and paired, the MV1C transmits data when the connected device requests it.

Interfacing to BLE

Note: 16-bit (4-digit) UUIDs are adopted standards. 128-bit (32 digit) UUIDs are custom services or characteristics.
