Hi, I'm trying to extract the noise and RSSI values from each received packet and have two questions. NOISE When reading a noise value from the notification structure (notif->u.noise.value) I get the correct values for notification frames (e.g. -93dBm), but for data frames I get the values that I don't know how to interpret. The positive noise values are in the range from 80 to 86. What do they mean? When extracting noise values from the u.frame.noise variable I get always zero (and this variable seems to be never used in the code). >From where to read the noise values for the data frames? Is this info available at all for the driver from the firmware? ...it looks like noise data are available for notification frames only. RSSI It's vice versa for RSSI... I have no problems reading RSSI values for data frames, but when reading RSSI for notification frames I always get zero. How to read RSSI values for the notifications frames? Thanks a lot for any help! ------------------------------------------------------------------------- Using Tomcat but need to do more? Need to support web services, security?
