BLUETOOTH LOW ENERGY (BLE)
The apex® Portable Scale with Remote Indicator Model apex-RI-C has a wireless transmitter
inside the weight indicator enclosure that can be configured for 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).

IMPORTANT!
If an attempt is made to turn the Bluetooth (BLE) off when a device is
connected to the scale, the display will show the error message

(in the smaller
upper seven-segment display) and
@#
(in the large lower seven-segment
display). This message will be shown until a key is pressed. Note that at this time,
the Bluetooth (BLE) is still on, only the message has been cleared. In order to turn
the Bluetooth (BLE) off, the device must be disconnected from the scale or the scale
must be turned Off and back On.
Bluetooth Pairing
To pair a Bluetooth-capable device with the scale, select the name of the scale from the list of
available connections: Apex Scale XX:XX:XX:XX:XX:XX. Note that the X’s represents the MAC
address of the BLE wireless transmitter in the scale weight indicator.
NOTE:
If there are multiple apex scales in close proximity, hold down the
key until the
scale software revision is shown. The display will then show the event counters, the Redbird
(
92`9
) software revision for the Wi-Fi and Bluetooth (BLE) module, and then scroll the
Bluetooth (BLE) advertisement data across the display. Note that the colons between the MAC
address will not be shown.
When a stable reading is achieved, and the scale is paired with a Bluetooth-capable device,
the reading will transmit when the connected device sends a request to receive data.
