Thanks for the reply.
I had the upgrade kit, so I've done the upgrade. Just have to figure out what config changes are necessary to run the range tests again.
I guess this thread should move forums now.
The application will never use ip, so the ConnectPort option is not suitable.
The Python Wiki is good, but concentrates on Digi hardware like ConnectPort , adaptors etc. This isn't surprising. Some of the code might be suitable. It is well documented.
What I really want is a well documented guide to show how to run Python on a PC and connect a ZB device to others for reading hardware.
An equivalent C version would be even better. When the code runs perfectly on the PC it could be easily ported to a microcontroller.
