Feedback on Bidir Fob
There exist 3 LEDs for all feedback, at the top of the fob,
out of the way of the hand that is holding it.
LEFT LED Color : AMBER
Function: To show RF communication, or that 2-way
communication is taking place.
Example: LEFT/AMBER LED flashes 1x in response to a
button being pressed when the RF command is sent,
and/or it can flash while communicating with the vehicle, or
waiting for response (example: while engine is cranking) .
Also this LED will blink in response to SMART entry
authentication.
For other cases, generally the Amber LED should operate
in a manner that is respective of the "Base SMART key".
CENTER LED Color: GREEN.
Function: Used to show positive feedback for a given
command.
Example: CENTER/GREEN LED is on for 1 second, to
provide status feedback for a given operation. It means:
Doors were locked, or engine was started, or engine is ON.
RIGHT LED Color: RED.
Function: Used to show negative feedback for a given
command.
There are 2 modes.
1. Out of range. In this case the red LED blinks distinctly
3 times,
Example: 3 times in 1 second. It means the fob could
not get acknowledgement from the car for 2-way
communication, or the vehicle battery is dead and
cannot respond.
2. Cannot Lock or Engine not running. In this case the red
LED is on for 1 second.

POWER MANAGEMENT
The Power Supply comprises a coin cell battery CR2032, filter capacitors,
diodes, and FETs, that provides power to the microcontroller, the powermanagement with charger and the RF circuit. A rechargeable battery (accu) of
the type LiFePO4 is included to supply higher currents in case of long range
transmission.
The accu type LiFePO4 is of the class Li-Ion cell, but with a safe chemistry.
There exists a certificate, that it is not dangerous / harmfull in the sense of
UN3480 and "Transportation without Class 9 is allowed".
