Hi,
I would like calculate the RSSI measurement in IEEE 802.15.4 TinyOS
implementation (TKN154) whose libs are located at "/tos/lib/mac/tkn154" and
test applications at "/apps/tests/tkn154" directories.
In the file “TKN154_MAC.h” located at "/tos/lib/mac/tkn154” exists a 8 bits
variable for store the RSSI value:
typedef struct {
uint8_t rssi;
uint8_t linkQuality;
uint32_t timestamp;
} ieee154_metadata_t;
However, rssi is defined like a unsigned integer, therefore, when rssi takes
negative values it crashes (by the fact of having defined rssi like an UNSIGNED
integer). Someone has had considered this?
The solution I've taken has been to change the value type of rssi from uint8_t
to int8_t in the ieee154_metadata_t, allowing you to take positive values.
Any help will be very appreciate.
Thanks a lot,
Felipe Cruz._______________________________________________
