Hi Miklos, I'm just wondering if you could help me please.
I've tried to implement a similar scenario to the TestFtsp application where three TestFtsp motes should send to the base station the local rather than the global reception timestamps of messages broadcast by a dedicated beacon mote programmed with RadioCountToLeds at periodic intervals (say each 1, 2 and 4 seconds). I found that the measured intervals (the difference between tni and tni+1 where tni and tni+1 represent, for example, local reception timestamps of beacon 'i' and beacon 'i+1' according to the local time of mote n) are almost the same for the three TestFtsp motes for the same beacons (i.e. raw data of the attached table). However, by comparing the measured intervals of the same TestFtsp mote (i.e. column data of the attached table) I'll get noticeable differences. In fact, I was expecting the opposite. Could you let me know whether what I got is wrong or not? and what is the reason for such results? BTW, I'm using tinyos 2.x and micaz platform and I'm not going here to test whether the TestFtsp motes are synchronized or not. Thanks in advance for any help. Omar
