SMA Commands
Once a TCP/IP connection has been made to the MV1C, you can issue SMA commands to it. The MV1C will respond to the SMA commands in the format shown in the Response column of the WI-FI AND BLUETOOTH SMA COMMANDS table on pages 14 and 15 of this manual.

BLUETOOTH LOW ENERGY (BLE)

The wireless transmitter inside the MV1C MedVue® Medical Weight Analyzer enclosure can easily be enabled and configured to connect to a Bluetooth- capable device using Bluetooth Low Energy (BLE). When possible, BLE standard specifications are used (those that are adopted by the Bluetooth SIG). Custom services were created to request indicator and scale information whose communication protocol was developed by the Scale Manufacturers Association (SMA).

Enable Bluetooth (BLE) Networking
The MV1C allows you to view and change the Bluetooth Settings without having to perform setup using the calibration switch. The operational settings are entered using the keypad.

•  The (CLEAR) key is used to begin setup review and clear incorrect entries.
•  The (ENTER) key is used to go into the menu item or save the setting.
•  The N/G (NET/GROSS) key is used to return to the previous menu item or setting.
•  The ID/H (ID/HEIGHT) key is used to advance to the next menu item or setting.
•  The 1 (YES) key is used to select ON or YES to various settings.
•  The 0 (NO) key is used to select OFF or NO to various settings.

NOTE:
Factory Network Settings are:
bLE ON/OFF = OFF, WIFI ON/OFF = OFF, and dHCP ON/OFF = ON.
To enable Bluetooth (BLE) networking:

1. With the MV1C turned ON and in the Gross weight mode, press and hold the CLEAR key for approximately 3 seconds.

2. The display will change to show SETUP REVIEW.

3. Release the CLEAR key.

4.  The display changes to show:
   

5. Press the ID/HEIGHT key until bLE/WIFI is shown in the Menu area of the display.

6. With bLE/WIFI displayed, press the ENTER key. The display will change to show REdbIRD REV and the Redbird Software version in the Settings area of the display.

7. Press the ENTER key. The display will change to show bLE ON/OFF and the current setting.

8. Press the 1 (YES) key to select on to enable Bluetooth, and then press the ENTER key.

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 an attempt is made to turn off the Bluetooth (BLE) when a device is connected to the MV1C, the display will show an error message ERR-bLE off. Before the Bluetooth (BLE) can be turned off, the device must be disconnected from the MV1C or the MV1C must be turned Off and back On.
Bluetooth Pairing
To pair a Bluetooth-capable device with the MV1C, select the name of the MV1C from the list of available connections: MV Scale XX:XX:XX:XX:XX:XX. Note that the X’s represents the MAC address of the BLE wireless transmitter in the MV1C.
NOTE:
If there are multiple MV1C’s in close proximity, press and hold the 0 (NO) key for about 5 seconds until the display changes to show REdbIRD REV and the Redbird Software version in the Settings area of the display. Release the 0 (NO) key. Next, press the ENTER key until the display is showing BLE in the Settings area of the display, with the Bluetooth (BLE) advertisement data MV Scale XX:XX:XX:XX:XX:XX scrolling across the Menu area of the display. Note that the X’s represents the MAC address and that the colons between the MAC address will not be shown. When the display stops scrolling, press the ENTER key. The MV1C MedVue Medical Weight Analyzer will return to the normal weight display. When a stable reading is achieved, and the MV1C is paired with a Bluetooth-capable device, the reading will transmit when the connected device sends a request to receive data.

•  If the weight is below zero (0), the weight you will see is zero (0).
•  If the weight is below zero (0), bit 4 of Weight Measurement will be set to 1, otherwise bit 4 is set to zero (0).

NOTE:
Maximum weight value displayed is 655.35 in both pounds (lb) and kilograms (kg).

BLUETOOTH INTERFACE STANDARD PROTOCOLS

Bluetooth Characteristic – Weight _Measurement: 0x2A9D
Widely accepted BLE GATT profiles are used to transmit data to other devices/software that have implemented these profiles. Data is passed via BLE using GATT characteristic “Weight Measurement” (0x2A9D) as defined by Bluetooth SIG. Refer to the data table below about Weight Measurement Characteristics.
Weight_ Measurement: 0x2A9D
Custom Services
Detecto SMA Service (0x907a0000-8699-47dd-ab30-d7aad5f83e54)
All custom characteristics have the same base number of the Service UUID 0x907aXXXX-8699-47dd-ab30-d7aad5f83e54 where the XXXX part distinguishes the service.

SMA Commands
The SMA commands shown in the WI-FI AND BLUETOOTH SMA COMMANDS table on pages 14 and 15 of this manual can be sent using the Detecto SMA Service’s Rx Cmd characteristic (0x907a0001-8699-47dd-ab30-d7aad5f83e54). Responses will put out a notification on the Tx Cmd characteristic (0x907a0002-8699-47dd- ab30-d7aad5f83e54).
WI-FI AND BLUETOOTH SMA COMMANDS
The format used to send SMA commands to the MV1C is:

• command

Where “command” is the ASCII letter(s), or the Hex Rep. listed in the table below. For example, Z or 0A5A0D would send the command to zero the scale. Note that the response of each command is listed under the Response column of the table.

• Any invalid command sent will return a question mark for a response. For example, sending a XZ will return 0A 3F 0D (?).
  Command| Hex Rep.| Response
  ---|---|---
  Z – zero scale| 0A5A0D| None. You should see scale zero itself.
  D – scale diagnostics| 0A440D| 0A 20 20 20 20 0D
  = means there are no errors, EEPROM error will show an E in the second space and C will show in the third space if there is a calibration error. 20 = SPACE

   • a. The Wi-Fi connection status (WIFI Connected, YES or no) will be displayed. Press the ENTER key to advance to the next setting.
   • b. The next four settings will be IP 1, IP 2, IP 3, and IP 4, the four octets1 of the IP address. Press the ENTER key to view the setting of each octet of the IP address. After viewing the IP 4 setting, press the ENTER key to advance to the next setting.
   • c. Next, 55Idwill be shown in the Settings area of the display, and the network name will be shown in the Menu area of the display. Press the ENTER key to proceed.
4. . If Bluetooth has been turned ON, bLE ON/OFF = on, the following will be shown:
   •  Next, bLE will be shown in the Settings area of the display, with the Bluetooth (BLE) advertisement data MV Scale XX:XX:XX:XX:XX:XX scrolling across the Menu area of the display. Note that the X’s represents the MAC address and that the colons between the MAC address will not be shown.
   • b. When the display stops scrolling, press the ENTER key.
5.  The MV1C MedVue Medical Weight Analyzer will return to the normal weight display.

1 If the Wi-Fi is not connected (WIFI Connected, no), and a scan of the Wi-Fi networks shows “REDBIRD_WIFI_XX:XX” AP, then the Wi-Fi module is in listening mode. Refer to the Configure Wi-Fi Network Module section for the procedure to set the Wi-Fi credentials.
