Web28 feb. 2024 · Key specifications for the BMD-330 module include a transmit power of +4 dBm and a receiver sensitivity of -96 dBm (BLE mode). It runs off a 3 volt supply and draws 7.0 milliamps (mA) at +4 dBm and 4.6 mA at 0 dBm in transmit mode. In receive mode, it draws 4.6 mA at 1 Mbit/s and 5.8 mA at 2 Mbits/s. WebFHSS systems are better for use within indoors and in severe multipath environments. This is because of the frequency hopping scheme could defeat the multipath by hopping to a new frequency.
