## Detailed Description

Client for AX25 communication.

## Constructor & Destructor Documentation

## ◆ AX25Client() [1/2]

AX25Client::AX25Client | ( | PhysicalLayer * | phy | ) |
| explicit

Constructor for 2-FSK mode.

Parameters

  phy | Pointer to the wireless module providing PhysicalLayer communication.

## ◆ AX25Client() [2/2]

AX25Client::AX25Client | ( | AFSKClient * | audio | ) |
| explicit

Constructor for AFSK mode.

Parameters

  audio | Pointer to the AFSK instance providing audio.

## Member Function Documentation

## ◆ begin()

int16_t AX25Client::begin | ( | const char * | srcCallsign,
|  | uint8_t | srcSSID = `0x00`,
|  | uint8_t | preLen = `8`
| ) |  |

Initialization method.

Parameters

  srcCallsign | Callsign of the source station.
  srcSSID | 4-bit SSID of the source station (in case there are more stations with the same callsign). Defaults to 0.
  preLen | Number of "preamble" bytes (RADIOLIB_AX25_FLAG) sent ahead of the actual AX.25 frame. Does not include the first RADIOLIB_AX25_FLAG byte, which is considered part of the frame. Defaults to 8.

Returns
  Status Codes

## ◆ sendFrame()

int16_t AX25Client::sendFrame | ( | AX25Frame * | frame | ) |

Transmit arbitrary AX.25 frame.

Parameters

  frame | Frame to be sent.

Returns
  Status Codes

## ◆ setCorrection()

int16_t AX25Client::setCorrection | ( | int16_t | mark,
|  | int16_t | space,
|  | float | length = `1.0f`
| ) |  |

Set AFSK tone correction offset. On some platforms, this is required to get the audio produced by the setup to match the expected 1200/2200 Hz tones.

Parameters

  mark | Positive or negative correction offset for mark audio frequency in Hz.
  space | Positive or negative correction offset for space audio frequency in Hz.
  length | Audio tone length modifier, defaults to 1.0.

Returns
  Status Codes

## ◆ transmit()

int16_t AX25Client::transmit | ( | const char * | str,
|  | const char * | destCallsign,
|  | uint8_t | destSSID = `0x00`
| ) |  |

Transmit unnumbered information (UI) frame.

Parameters

  str | Data to be sent.
  destCallsign | Callsign of the destination station.
  destSSID | 4-bit SSID of the destination station (in case there are more stations with the same callsign). Defaults to 0.

Returns
  Status Codes
