Configure Wi-Fi Network Module
Without Wi-Fi credentials, the Wi-Fi module will enter listening mode, in which it functions as a
Wi-Fi access point. The SSID of the AP is of the form “REDBIRD_WIFI_XX:XX”, where XX:XX
is the last 4-digits of the MAC address. Use a Wi-Fi device, such as a Smartphone, tablet, or
laptop to connect to the indicator. If the connection fails, try moving the indicator to another
location or turn the indicator off and back on.
When the connection has been made, open a web browser and go to the location
redbird.com. The “Configure Wi-Fi” page should appear.
Click on the Scan button to see a list of available Wi-Fi networks.

SMA Commands
Once a TCP/IP connection has been made to the indicator, you can issue SMA commands to
it. The indicator 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 11 and 12 of this
manual.

BLUETOOTH LOW ENERGY (BLE)
The wireless transmitter inside the 750C weight indicator 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
NOTE: Factory Network Settings are: 2/4>, =5->, and 38>, (= Off and = On).
To enable Bluetooth (BLE) networking:
1. With the indicator turned Off, press and hold the key and then press the key to
turn the indicator on.
2. The indicator will perform a lamp test, display the model number and software revision,
and then display the $'#> prompt.
3. When the is display showing $'#>, release the key.
4. Next, press the key until the prompt 2!> is displayed.
5. With the display showing 2/4> press the key to view the current setting. Press the
aor bkeys to select (1 = On), and then press the key to save it.
6. Press the key repeatedly until the indicator resets and displays weight. The indicator
is now ready to pair with a Bluetooth-capable device.
IMPORTANT! If an attempt is made to turn the Bluetooth (BLE) off when a device is
connected to the indicator, the display will show an error message @!. Before
the Bluetooth (BLE) can be turned off, the device must be disconnected from the
indicator or the indicator must be turned Off and back On.
Bluetooth Pairing
To pair a Bluetooth-capable device with the indicator, select the name of the indicator from the
list of available connections: 750 Scale XX:XX:XX:XX:XX:XX. Note that the X’s represents the
MAC address of the BLE wireless transmitter in the indicator.
NOTE: If there are multiple indicators in close proximity, press and hold the `key for about 5
seconds until the display shows the prompt 92`9>. Next, press the key until the display is
showing 2/4`13, the Bluetooth (BLE) advertisement data. Press the key again and the
BLE advertisment data will scroll across the display. Note that the colons between the MAC
address will not be shown.
When a stable reading is achieved, and the indicator is paired with a Bluetooth-capable device,
the reading will transmit when the connected device sends a request to receive data.

<LF>command<CR>
Where “command” is the ASCII letter(s), or the Hex Rep. listed in the table below. For
example, <LF>Z<CR> 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 <LF>XZ<CR> will return 0A 3F 0D (<LF>?<CR>).
