Detailed Description

map that keeps track of the list of used channels and calculates the next channel based on the last used channel

Member Function Documentation

data_channel()

unsigned bluetoe::link_layer::channel_map::data_channel

(

unsigned

index

)

const

the BLE channel hop sequence is 37 entries long, after 37 hops, the sequence starts again. This function returns the entries in this sequence. The channel for the first entry is given by calling the function with index = 0, the last entry with index = max_number_of_data_channels -1

reset() [1/2]

bool bluetoe::link_layer::channel_map::reset

(

const std::uint8_t *

map

)

sets a new list of used channels and keeps the old hop value.

Precondition

reset( const std::uint8_t* map, const unsigned hop ) must have been called before, to have an old hop value

reset() [2/2]

bool bluetoe::link_layer::channel_map::reset	(	const std::uint8_t *	map,
		const unsigned	hop
	)

sets a new list of used channels and a new hop value.

The function returns true, if the given parameters are valid. A valid map contains at least 2 channel. A hop increment shall have a value in the range of 5 to 16.

Member Data Documentation

max_number_of_data_channels

constexpr unsigned bluetoe::link_layer::channel_map::max_number_of_data_channels = 37

staticconstexpr

the number of channels, used as data channel.
