Connexx 8 "fatal error"

Showed error and caused a dup post.

Your aids will be marked red=right and blue=left. They can be a dot or a larger mark. My aid has dots in the battery door. Some are a little banner with color and something to do with the model/brand.

The color marks on my bodies match the receivers, right all red, left all blue, however it’s the Connexx software/hardware that thinks the right is a left with the wrong receiver attached. There must be some internal difference beside the color codes that determines whether a given body is a right or left.

This may not be an issue when programming using cables, but since the wireless does not know which is which, it must interrogate the devices for that info. My right one seems to be coded wrong electrically or in software?? The color marks are just what someone added, and may not match the internal electronics/software.

Does anyone know or have a guess at how this is determined within the body and/or firmware of the aid itself?

HAs are interchangeable. Right/left doesn’t matter until you put right/left receivers on, or also red/blue identifiers/markers as visual aids. The fitting software knows which is which because it writes a different audiogram to each HA and when it does that, the software also marks the internal programming as Right/Left. That’s for wired fitting.

I don’t know how this works for wireless fitting? But you might try this experiment. Put the Connexxlink on your desk. Place the working HA on one side of the Connexxlink and note whether the Right/Left gets connected via wireless communications. Then physically move the HA location to the other side of the Connexxlink to see if the right/left will get changed. If it does switch sides then I am guessing that the wireless signals from Connexxlink are beamed to the right or left as opposed to a 360 degree circle and will start talking to whichever HA answers the communications protocol.
