Hello,

Does it works under 915MHz?

Andre, you should be able to set the frequency to 915MHz as it is controlled by the device but note that in the UK 868 MHz is used as this is exempt from licenced 

    # set frequency
    frf = int((self._freq * 1000000.0) / FSTEP)
    self._spi_write(REG_06_FRF_MSB, (frf >> 16) & 0xff)
    self._spi_write(REG_07_FRF_MID, (frf >> 8) & 0xff)
    self._spi_write(REG_08_FRF_LSB, frf & 0xff)
