Team 
,
bit short on time today. However I got one RFbee working and reprogrammed 
(need to fix some cabling for the second one )
@Rich: I added a number of serial.println’s without running out of RAM so I presume something else is wrong, you might want to post your full code so we can see what is happening.
@Icing: great to see your 1.1a3, I already had a quick look and as usual I have some suggestions which I hope to post in the coming days.
I checked the Xbee doc and that uses to mark the end of an AT command so I think its a good move to do the same.
(I’ll try to fix it in an 1.1a4 )
Kind regards,
Hans
