PHONELAMPMODE_ Constants

The PHONELAMPMODE_ bit-flag constants describe various ways in which a phone's lamp can be lit.

PHONELAMPMODE_DUMMY

This value is used to describe a button/lamp position that has no corresponding lamp.

PHONELAMPMODE_OFF

The lamp is off.

PHONELAMPMODE_STEADY

Steady means the lamp is continuously lit.

PHONELAMPMODE_WINK

Wink means normal rate on and off.

PHONELAMPMODE_FLASH

Flash means slow on and off.

PHONELAMPMODE_FLUTTER

Flutter means fast on and off.

PHONELAMPMODE_BROKENFLUTTER

Broken flutter is the superposition of flash and flutter.

PHONELAMPMODE_UNKNOWN

The lamp mode is currently unknown.

The high-order 16 bits can be assigned for device-specific extensions. The low-order 16 bits are reserved.

Where the exact on and off cadences can differ across phone sets from different vendors, mapping of actual lamp lighting patterns for most phones onto the values listed above should be straightforward.
