Atmel are replacing the original Zigbit modules with a range of new ones. They are bigger and about 3x the price, most have chip antennas.
We use the original modules -24 and -900 with external antennas. We can use LwMesh in 784Mhz, 868Mhz, 915Mhz and 2.4Ghz bands with a single footprint module. The new modules have gone in a different direction and this is now not possible.
The only solutions I can see are :-
1) Produce our own modules or put the chips direct onto the pcb.
2) Use the new MCU-less modules and port the stack onto the existing non Atmel MCU. But this may not be allowed by the LwMesh license.
Any other solutions anyone ?
