I am measuring the power consumption of my sensor node. I use an EFM32 Microcontroller with Microchips RN2483 module for LoRaWAN communication. The datasheet states that the current consumption is around 39 mA when transmitting with an output current of 14dBm and an supply voltage of 3.3V. However, i’m measuring a current of 28 mA when transmitting a packet with the same parameters (14 dBm and 3.3V). Also, i disabled adaptive datarate as i found that this can reduce transmitting power, but this didn’t have an effect. It is a good thing that the current consumption is lower than expected, but i wondered how this happened. Are there other things that lower the current consumption when sending a packet?
Thanks in advance,
