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.
If the PER is too high, it
would require checking the
configuration of the system
(ranges, operating channels,
etc.).
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.
