Region Settings

Make sure connect the appropriate wire antenna length when using the SAMD21 Pro RF and configuring the code to communicate at the correct frequency in your region. The default is set to 915MHz in the example code. If you are using the board for 868MHz, make sure to:

  • adjust the wire length
  • configure the code to operate in the correct region

We recommend testing a pair of SAMD21 Pro RF boards with the point to point radio example to see if the boards are transmitting/receiving with the antenna and frequency to verify that the boards are working as expected.
