Hello,

I am trying to run the attached communication test program on the eMote 1.0.11_R12, with one .NOW mote set up as sender (MODE_SEND) and the other one as receiver (MODE_RECEIVE). This program is based on the Radio Signal Meter app note. Described simply, the sender sends rounds of 1000 packets each with inter-packet intervals of 100 ms (the variable SendDelay). At the end of each round, the sender is made to sleep for 10 s while the receiver enters the round statistics into the NOR datastore (this involves a timer at the receiver's end, which has not been implemented in the version attached in order to keep the code simple. So, the receiver receives continuously).

I have the following issues with running the program on the eMote 1.0.11_R12:

Urgent issue: The receiver program seems to crash within the first 10 sender rounds. The receiver simply gets stuck at a certain packet after 3, 5 or 7 rounds (the exact round number in an experiment is nondeterministic, though it never seems to go past 7 rounds.)



Once the program is deployed and run in the receiver mode and incoming packets are processed, subsequent application deployments cannot be made. The errors reported are typically: "Unable to communicate with device Serial:COMxy" or "An error has occurred: please check your hardware."



Radio receive errors, though quite rare, do seem to occur. Most of them are of type "Error downloading message", though once I have also seen "Message is too big".


Thanks and Regards,
Dhrubo.
