Need RSSI information
« on: August 03, 2016, 04:25:45 am »
Hello.
I Am publishing the mcModules RSSI with MQTT so that I could see the connection status and all other information from the mcModules in one place.
But i need some more information about the RSSI, the devices that is close to the mcGateway is around 188-190 I have a couple of mcModules outside and one of them reports back 158.
I have one module that is also reporting 158 and if I move that device 1 meter and close a door then it does not report anything anymore.

So my question is, what is good and what is bad RSSI, it seems like this
190 - Perfect
158 - poor
less than 158 - not work at all

The RSSI numbers are signed bytes that are displayed as unsigned bytes. (The bug is in the list to be fixed.) The value of 190 is -30dB and 158 is -98dB

The official sensitivity of the device is about -96db so yes you reached the limit
