RSSI distance range value

edited September 2014 in Hardware
what is the maximum RSSI value (range value)? , when i tested in my metwear with nearby mobile, it's showing RSSI value "-65". let me know which is minimum range value and maximum range value,
And how to improve ble antenna range, like position of placing board to get more accuracy range.

  • @samsgate,
    RSSI values depends on each BLE device at the circuit level (we are talking antenna strength and configuration here). 
    -65 is a typical value but you can expect everything from -40 to -90 and the occasional erroneous 127 value.
