Bluetooth LE Property 0x13 - Bluetooth Status LED Functionality Control
(Bluetooth LE Only, Pairing Modes Only)
Bluetooth LE Property ID:
0x13
Get Property: Yes
Set Property: Yes
Non-Volatile: Yes
Default value: 0x00 (Off During Bluetooth LE Connection)
This property is a one byte value that controls the Bluetooth Status LED functionality. On devices that do
not have a dedicated Bluetooth Status LED, the device always returns 0x00.
When this byte is set to 0x00, the Bluetooth Status LED is OFF when the device is connected to a host via
Bluetooth LE, which saves battery power.
When this byte is set to 0x01, the Bluetooth Status LED is ON when the host has established an
encrypted
Bluetooth LE connection with the device, indicating the device is accepting commands and transactions.
This provides additional visual cues for cardholders and operators, but uses more battery power.
When this byte is set to 0x02, the Bluetooth Status LED is ON when the host has established
any
Bluetooth LE connection with the device. If the connection is not yet encrypted, the device does not
process commands or transactions. This option can be useful for diagnosing whether a host is connected
to the device. When a host is connected to the device, the device does not advertise and is not able to
connect to any other host until the connection is broken. This option was added to eDynamo Bluetooth
LE firmware 1000002650C01 in July 2016.
This property is stored in non-volatile memory, so it persists when the device is power cycled. This
property would typically only be changed once during device configuration if needed. Modifying this
property too many times wears out flash memory.
