0xFFB1
Max Retry error, indicating a packet loss
The W-Master cannot create a message to
W- Device after MaxRetry attempts.
This error indicates that one packet failed
to be transmitted successfully. This can be
for example the result of a noisy
environment (RF-wise). It affects the PER
of the system.
Error
If the PER is too high, it would
require checking the
configuration of the system
(ranges, operating channels,
etc.).
0xFFB2
IMA timeout
The W-Master did not receive a message
from the connected W-Device within the
IMA timeout. This error indicates that the
IOLW connection failed. Possibly this
leads to "Communication loss" 0xFF22.

Device to the TigoBridge
