States the quality of the reception link of the connection between the equipment and the AirGate-Modbus father with

which it is paired. This value is obtained when measuring the power of the last packet received. This power is measured

in dBm, which is a logarithmic measurement of power in mW. The LQI can vary between -100dBm (worst reception

quality) to -15 dBm (best reception quality).

States the quality of the reception link of the connection between the AirGate-Modbus child whose Modbus address was

filled-out in the ADDR_FILHO register. This value is obtained when measuring the strength of the last packet received.

This power is measured in dBm, which is a logarithmic measurement of power in mW. The LQI can vary between -

100dBm (worst reception quality) to -15 dBm (best reception quality).
