Phil, Great to hear on the CTP 1) We are running deployed around the office here. Simple temp gathering 2) The platform is the isi1000, this is a hybrid we have made that has the MSP430 on it with the CC1000 radio. All other apps seem to work as expected with the exception of this one (Antitheft). I only had to do some minor changes in the CC1000 stack to remove the ATMEGA dependencies and then wire it up to the MSP. 3) Using TinyOS 2.0.1 (latest release from early May). I was wondering if this may have to do with some of the mesh statistics for the routing in the /ctp (rssi/parent,etc). Reason is that sometimes I can reset one node and 5 others will start reporting in again as if they now have a valid path to the root.
