BOOL MiMAC_SetChannel(
    BYTE channel, 
    BYTE offsetFreq
);

Description

This is the primary MiMAC interface for the protocol layer to set the operating frequency of the RF transceiver. Valid channel number are from 0 to 31. For different frequency band, data rate and other RF settings, some channels from 0 to 31 might be unavailable. Paramater offsetFreq is used to fine tune the center frequency across the frequency band. For transceivers that follow strict definition of channels, this parameter may be discarded. The center frequency is calculated as (LowestFrequency + Channel * ChannelGap + offsetFreq)

Preconditions

Hardware initialization on MCU has been done.

Parameters

Parameters	Description
BYTE channel	Channel number. Range from 0 to 31. Not all channels are available under all conditions.
BYTE offsetFreq	Offset frequency used to fine tune the center frequency. May not apply to all RF transceivers

Returns

A boolean to indicates if channel setting is successful.

Remarks

None

Example

Copy Code

// Set center frequency to be exactly channel 12
MiMAC_SetChannel(12, 0);
