Hi, Sara I am not sure if you have found out the
reason why your RSSI value is not correct. Basically CC2420 uses 2’s
complement for RSSI value. https://mail.millennium.berkeley.edu/pipermail/tinyos-help/2005-June/009922.html
However, I have also done my measurement on the signal strength, the
maximum RSSI value that I get is 0xFA, i.e. RSSI_VAL = -3, and the signal
strength is -7 -45 = -52 dBm. In other word, the maximum signal strength will
not go above negative value? I am not sure about this, would you please
validate this for me. Thank you. Lin |
