I've seen your PM but you'll have to wait for it... don't worry, only a couple of days!
No problem, I'm certainly not in any hurry for the firmware - I've got a few more things to take care of first (like building an I2C EEPROM board).
It shouldn't be very important (though Zigbee points to be the next Bluetooth) but, as any Arduino follower, I do hate propietary protocols
I agree - This is the biggest problem I have with Digimesh - it's not open.
I haven't gotten very far with Digimesh yet (I finally got my API mode code passing packets now; they've tweaked the format of the TX/RX packets just enough to confuse a newbie like me) but it gives me what I wanted - mesh networking with Series 1 hardware.
So far, so good. It's certainly not compatible with any of the other firmware, so that's an issue as well.
I'm on vacation until next year so I've been writing code late into the night. I'll report back more on Digimesh in the next few days.
I think the only reason to chose Digimesh over the old Beta firmware is support - any bugs in the beta code will stay there.
I'm only going to be interested in networking with my own nodes, so even if the older firmware isn't compatible with anything else I should be fine.
