Are the packet corruption caused by fase positive of CRC? Essentially I'm just trying to see if these corrupted packets are due to the inherent limit of the radio stack or some bug in my code. Best regards, On Wed, Apr 20, 2011 at 3:07 PM, Xiaohui Liu wrote: > Thanks for your reply. > > So you

Thanks for your reply. So you mean received packet payload can be different from its payload at the sender side? If so, what's the probability for this case to happen, approximately? Does this apply to UART stack as well besides radio stack? On Wed, Apr 20, 2011 at 2:40 PM, Omprakash Gnawali wrot

[Tinyos-help] is packet corruption normal?

Hi everyone, A packet is sent with *AMSenderC[AM_TYPE].Send.send* and it has a payload of, say, 0xFF. After the packet is received by * AMReceiverC[AM_TYPE].Receive.receive*, sometimes I find it has a different payload (i.e., not 0xFF). But the probability for this to happen is low, around 1 out o
