Re: [Tinyos-help] LQI and RSSI values on iris

2011-04-19 Thread Peter Trenkamp
Hello Umit and Miklos, I don't think there is a conversion formula for the LQI between the values from RF230 chip (Iris mote) and CC2420 (Shimmer mote). The IEEE 802.15.4 standard defines that this parameter have to use a range from 0 to 255 but a specific formula to calculate the LQI is not defined.
