I am also trying to achieve a similar type of outcome, where as I can use one wixel connected to a PC via USB, to communicate with several other Wixels connected to other devices via UART.
Obviously this will be on a one-to-one basis so the Wixel will need to dynamically change the address to talk to any of the others.
I have read through this post and have been looking at modifying the wireless serial app.
I have dumped in Geoffs complete code that he posted here, including the updated lib file etc.
I then ran this app on the Wixel to try it out.
I communicated between the 2 wixels via 'HT Comm'. And the wireless conenction worked as expected. i.e. type 'a' at one com port and 'a' was received at the other, showing that the wireless comms was good.
I assumed that by typing a '0', followed by a new radio channel i.e. '6', that this would change the new channel to channel '6'. Instead, it juse sent a '6' accross the radio link.
Is this meant to happen? Have I made the wrong assumption to how this shouuld work? I apologise in advance, as there are a few holes in my C knowledge as I have not had much experience.
Any help would be much appreciated.
