Optimal LoRa Radio Settings #4

Closed thejimster82 closed 4 years ago

thejimster82 commented 4 years ago

Right now, the LoRa radio reaches 130mA of current when sending packets. It is possible to change the parameters on the radio in a way that might reduce this current draw, especially in the circumstance that the user is very close to their gateway.

If the sensor box is closer to the gateway, the LMIC library allows for changing the TX power:

    // Set the transmission power (0 - 14):
    LMIC_setDrTxpow(DR_SF7, 0);
