Hello
I am using micaz(2.4Ghz), tinyos 2.0.1, linux(fedora 6), mib510.
Can I use float or double type in message when I want to use mig?
When I used only uint type, MsgReader with mig works well, but when I used
double(or float) type, MsgReader with mig doesn't work.
1) OK : only when I used int type, I found out result through MsgReader as
followings
- message define
typedef struct HelloMsg {
uint16_t nodeid_; // node id
uint16_t type_;
uint8_t x_;
uint8_t y_;
uint16_t seqno_; // message sequence number
uint16_t counter; // for blinking
} HelloMsg_t;
- result (MsgReader)
> java net.tinyos.tools.MsgReader HelloMsg
1185020442862: Message <HelloMsg>
[nodeid_=0x0]
[type_=0x1]
[x_=0x0]
[y_=0x0]
[seqno_=0x0]
[counter=0x40a0]
2) Error : when I used double type in message, I could see error in
MsgReader as following
- message define
typedef struct HelloMsg {
uint16_t nodeid_; // node id
uint16_t type_;
uint8_t x_;
uint8_t y_;
double temp_; // <-- I also have tested in case of "float
temp_"
uint16_t seqno_; // message sequence number
uint16_t counter; // for blinking
} HelloMsg_t;
- result (MsgReader)
> java net.tinyos.tools.MsgReader HelloMsg
receive error for HelloMsg (AM type 6): invalid length message
received (too short)
......
Thanks.
