Detailed Description

Receiver settings that decide how weak a reply the reader can still make sense of.

Where transmit power sets how far the reader reaches, these set how far it listens. Both are worth lowering for a tag that sits on the antenna: a reader configured for a metre and a half misses most inventory rounds at contact, however strong the reply is

uint16_t m5::unit::m100::DemodulatorParameters::threshold {DEMODULATOR_THRESHOLD_DEFAULT}

Demodulation threshold. A lower one reaches replies of lower RSSI but is less stable, and below some point nothing demodulates at all; a higher one only reaches stronger replies, which means shorter range, and is more stable
