Hi all I had the test that it sends and receives between BaseStation and embedded board.
My test is the same as follows Sensor node --> BaseStation --> embedded board I had the tests with two tinyos-2.x version First, tinyos-2.x version of BaseStation is 2.0.1-3 When we test with 2.0.1-3, embedded board receives the correct value as below : Correct value : 7e 45 00 ff ff 00 05 37 22 0c 69 05 00 00 00 00 00 8f fd ff 00 ff fe 00 00 05 33 33 00 00 00 00 00 02 50 d5 42 88 ff fd ff ff fe 00 00 05 ff 02 00 00 00 00 00 00 00 00 00 00 00 00 00 02 3a 85 00 80 32 00 00 00 00 09 35 7e Second, tinyos-2.x version of BaseStation is 2.0.1-5 When we test with 2.0.1-5, embedded board receives the wrong value as belos : Wrong value : fe 85 00 ff ff 00 05 77 42 0c ec 05 00 00 00 00 00 0f fd ff 00 ff fe 00 00 05 73 73 00 00 00 00 00 02 a0 b5 82 18 ff fd ff ff fe 00 00 05 ff 02 00 00 00 00 00 00 00 00 00 00 00 00 00 02 7a 05 00 00 72 00 00 00 00 04 71 fe If you check over the values, you would recognize some weird regulation. 7e --> fe 45 --> 85 37 --> 77 22 --> 42 42 --> 82 I think 4 bit of one byte change through some masking or shift. I don’t know exactly. Don’t serial communication of tinyos-2.0.1-5 have the any problem? My embedded board is arm9 and linux kernel-2.4.18 I would speak again that when we had a test with tinyos-2.0.1-3 of BaseStation, we received the correct value. If you know this problem, let me know. Thank you in advance.
