RSSI values not caught by if statement

[JonSilver]

Just stumbled upon your code and thought I'd point out that your if statement for rssi values allows the values at the top ends of your ranges to drop through to the end, resulting in no bars.

To resolve this:

    if (RSSI >= -55) { 
      bars = 5;
    } else if (RSSI < -55 & RSSI >= -65) {
      bars = 4;
    } else if (RSSI < -65 & RSSI >= -70) {
      bars = 3;
    } else if (RSSI < -70 & RSSI >= -78) {
      bars = 2;
    } else if (RSSI < -78 & RSSI >= -82) {
      bars = 1;
    } else {
      bars = 0;
    }

The if statement may be even simpler. Like this:

bars = 0;
 if (RSSI >= -82) bars = 1;
 if (RSSI >= -78) bars = 2;
 if (RSSI >= -70) bars = 3;
 if (RSSI >= -65) bars = 4;
 if (RSSI >= -55) bars = 5;
