Possible antenna information nibble values:
 0b0000 – Antenna is changing state (calibration is in progress, switching on/off is in progress, etc.)
 0b0001 – Antenna off
 0b0010 – Antenna on
Status byte examples:
 Byte 1 = 0x11: both antennas are off
 Byte 1 = 0x21: antenna B on, antenna A off
 Byte 1 = 0x22: impossible (both antennas active)
 Byte 1 = 0x10: antenna A is changing state, antenna B is off
7.6 Error and event codes
This is the error / event codes table. The code message can be related to an antenna (sent in a TPDO1/2)
or related to the CAB system (sent in a TPDO3).

Description
AA_ERROR_NONE
0x0000
No error
AA_ERROR_ANTFAIL
0x0001
Antenna fail
AA_ERROR_CRC
0x0002
CRC computation mismatch
AA_EVENT_CALIB_END
0x0100
Antenna calibration has finished
AA_ERROR_V24_BAD
0x0103
24 V power malfunction. This value is used in a PDO3 sent
once when the power voltage goes under 24V-20% (19.2
V). When the power goes above 22.6V (24V – 10%) a PDO3
with AA_ERROR_NONE message is sent to communicate
that the power supply voltage has reached a safe value.
