Hi all,
i have two questions to you;
1) i'm using Oscilloscope and Delta apps, and i want to convert raw data from ADC into SI data; i 'm using the paper "getting data from moteiv tmote sky sensors" at www.moteiv.com. the external temperature sensor give me a value = 6965 (1B35 in hex) that means a temperature of 30,05 ° C but in the room there is a temperature of maximum 25°! where is the problem? i've tried with other tmote sky modules but the value is the same. is this a problem dependent from sensor, software or is wrong the formula: temp=-39.60 + 0.01 * Reading ?
2) when i log packets from oscilloscope or delta apps , i see that the "data" bytes in the multihopmsg are written from right to left, is it normal? i put the log below:
1157967601703 Message <MultiHopMsg>
[sourceaddr=0x9]
[originaddr=0x9] [seqno=0x35f]
[originseqno=0x35f]
[ttl=0x0]
[id=0x21]
[data="" 0x3 0x0 0x0 0x93 0xb 0x35 0x1b 0x52 0x4 0xbd 0x0 0x7e 0x0 0x3 0x0 0x7e 0x0 ]
the "data " bytes are : the first four (0x5b 0x3 0x0 0x0) are seqno, after 2 bytes (0x93 0xb) needs to be read B93. and the others in the same mode. it's right??
thank you for help me and sorry for the not so good english.
Bye
