SM12.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 microstrip line to match the impedance of the device.
  • Ensure that the devices are configured to use the same spreading factor, bandwidth, and coding rate. Also, verify that the devices are operating on the same frequency band and have a clear line of sight.
  • The maximum transmit power of the SM12.TCT is +20 dBm. You can adjust the transmit power by using the `setTxPower()` function in the Semtech API, 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 API. You can define a list of frequencies and use the `setFrequency()` function to switch between them. The device will automatically hop between the defined frequencies.
  • A quarter-wave monopole antenna or a dipole antenna with a 50-ohm impedance is recommended. The antenna should be designed to operate at the desired frequency band and have a gain of around 2 dBi to 5 dBi.
