Member Function Documentation

◆ addChannel()

error_t LoRaMacCN779::addChannel ( uint8_t  id,
ChannelParams_t  params 
)
virtual

Add a channel.

Adds a new channel to the channel list and activates the id in the channel mask. The frequency and DR specified in the params MUST be valid values for each regional parameters specification.

Parameters
[IN]id - Id of the channel.
[IN]params - Channel parameters to set.
Returns

Implements LoRaMac.

◆ getChannel()

const ChannelParams_t* LoRaMacCN779::getChannel ( uint8_t  index)
virtual

채널 정보를 가져옵니다.

Parameters
index채널 번호 (0 ~ MaxNumChannels)
Returns
  • Non-NULL: 유효한 채널 정보
  • NULL: 유효하지 않은 index, 또는 비활성화된 채널

다음 예제와 같이 현재 설정된 채널 정보들을 출력할 수 있습니다.

Implements LoRaMac.

◆ getMaxPayload()

uint8_t LoRaMacCN779::getMaxPayload ( uint8_t  dr,
bool  repeater = false 
)
overridevirtual

최대 application payload 길이(N)를 가져옵니다.

Parameters
drDR index
repeaterRepeater mode 사용 여부
Returns
  • 0이 아닌 값: 최대 application payload 길이
  • 0: 잘못된 DR

최대 application payload 길이(N)는 최대 payload 길이(M)에서 FOpt 길이를 뺀 값입니다. FOpt의 길이는 최소 8-byte 이며 더 커질 수도 있습니다.

Implements LoRaMac.

◆ removeChannel()

error_t LoRaMacCN779::removeChannel ( uint8_t  id)
virtual

LoRaMAC channel remove service.

Deactivates the id in the channel mask.

Parameters
[IN]id - Id of the channel.
Returns

Implements LoRaMac.
