Bug 2025

Summary:	Changing the channel doesn't affect the Tx params

Description Tommaso Pecorella 2014-12-04 10:44:04 UTC

The bug is in this function:
void LrWpanPhy::PlmeSetAttributeRequest (LrWpanPibAttributeIdentifier id,
                                         LrWpanPhyPibAttributes* attribute)

if this function is used to change the channel, m_txPsd is not recomputed.

It should be recomputed. As a matter of fact using the same function to change the Tx power leads to...
            m_phyPIBAttributes.phyTransmitPower = attribute->phyTransmitPower;
            LrWpanSpectrumValueHelper psdHelper;
            m_txPsd = psdHelper.CreateTxPowerSpectralDensity (m_phyPIBAttributes.phyTransmitPower, m_phyPIBAttributes.phyCurrentChannel);

Notice the channel number in the last function call.
