You could just change the settings for each bitrate to match that of the sending node, but how do you know when to listen to which one?
Indeed. There are potential solutions, for example the gateway listens on one set of settings for half the time and on the other for the other half, it should completely reject packets with the incorrect settings. Retries would eventually get the packet through on the right half, but that could be costly for power so then you might want to use a real-time counter on the node to ensure it only wakes up in the correct half, and synchronises it's timer when it gets a response from the gateway. It all gets a bit hairy. An easier approach might be to just have two gateways.

So, as is it now, you have to settle for one setting and stick to it? One thing would be great, if gateway app would be able to listen to more serial ports, then this could be solved even for different freq. entirely. Not something you would need for a house alone.
