Struct JoinPlan 

pub struct JoinPlan<'a> {
    pub channels: ChannelBlock,
    pub accept_start_hz: u32,
    pub accept_step_hz: u32,
    pub rx2_start_hz: u32,
    pub rx2_step_hz: u32,
    pub plan: &'a ChannelPlan<'a>,
}

A run of join channels that puts a device on one plan, for a region that picks the plan by the channel a device joined on.

RP002-1.0.5 section 3.9.2 has CN470-510 devices scan twenty common join channels, each tied to one of four plans. The channel a join accept answers decides the plan, where the accept arrives, and where the second receive window listens afterward.

Fields

channels: ChannelBlock

The join channels this run covers, with the data rates a request may use on them.

accept_start_hz: u32

Where the join accept answering the first channel of the run arrives, in hertz.

accept_step_hz: u32

How far the accept frequency moves for each next channel, in hertz.

rx2_start_hz: u32

The second receive window’s frequency after joining on the first channel, in hertz.

rx2_step_hz: u32

How far that frequency moves for each next channel, in hertz.

plan: &'a ChannelPlan<'a>

The plan a device joined on these channels follows.

Implementations

impl<'a> JoinPlan<'a>

pub const fn new( channels: ChannelBlock, accept: (u32, u32), rx2: (u32, u32), plan: &'a ChannelPlan<'a>, ) -> JoinPlan<'a>

Builds a run of join channels.

Arguments

• channels - the join channels and their data rates.
• accept - the accept frequency for the first channel and its step, in hertz.
• rx2 - the second window’s frequency for the first channel and its step, in hertz.
• plan - the plan a join on these channels puts a device on.

Returns

The run.

pub const fn accept_hz(&self, offset: u16) -> Option<u32>

Returns where the join accept answering one channel of the run arrives.

Arguments

• offset - the channel’s position in the run.

Returns

The frequency in hertz, or None past the end of the run.

pub const fn rx2_hz(&self, offset: u16) -> Option<u32>

Returns where the second receive window listens after joining on one channel of the run.

Arguments

• offset - the channel’s position in the run.

Returns

The frequency in hertz, or None past the end of the run.
