SR12.TCT Frequently Asked Questions (FAQs)

  • A 4-layer PCB with a solid ground plane and a separate power plane is recommended. Keep the RF traces as short as possible and use a 50-ohm impedance-controlled line to minimize signal reflections.
  • Ensure that the devices are configured to use the same frequency band, spreading factor, and coding rate. Also, make sure that the devices are within range of each other and that there is no significant interference in the environment.
  • The maximum transmit power of the SR12.TCT is +20 dBm. You can adjust the transmit power by using the `setTxPower()` function in the Semtech LoRaWAN library, which allows you to set the power level from +2 dBm to +20 dBm in 1 dB steps.
  • Frequency hopping can be implemented using the `setFrequency()` function in the Semtech LoRaWAN library. You can define a list of frequencies and use the `setFrequency()` function to switch between them. You can also use the `setDutyCycle()` function to set the duty cycle of the transmission.
  • The current consumption of the SR12.TCT varies depending on the mode. In transmit mode, the current consumption is typically around 40 mA. In receive mode, it is around 10 mA. In sleep mode, it is around 1.5 mA. The exact current consumption may vary depending on the specific application and configuration.
