[1.0.0] - pre 2022-05-10

First (more or less) working version.

[1.0.1] - 2022-05-10

Added

  • Support for saving settings to internal FLASH

[1.0.2] - 2022-05-11

Added

  • APRS settings can now be saved in FLASH
  • logging to serial USB is disabled when in KISS mode (but KISS mode still needs to be implemented)

[1.0.3] - 2022-05-12

Added

  • All settings (LoRa and APRS) can now be saved to FLASH.
  • Command added for restarting LoRa radio when settings are alterred: "restart lora"
  • Received LoRa frames can now be converted to proper AX25 frames (needed for KISS TNC functionality)
  • KISS mode works for receiving (LoRa -> USB port)
  • KISS mode for transmitting in early phase of development
  • Can enter KISS mode with command "kiss 1" and exit KISS mode with command "sudo kissparms -p ax0 -x"

[1.0.4] - 2022-05-13

Added

  • Fully functioning KISS TNC, but repeater flag could not be tested because LoRa APRS software in general is a mess. It appears that nobody reads the AX.25 standard anymore. This software probably is also not up to spec. But at least I tried! You should too: http://www.ax25.net/AX25.2.2-Jul%2098-2.pdf

[1.0.5] - 2023-12-19

Changed

  • Nothing changed, last version without telemetry. Tagged for archiving purposes.

[1.1.0] - 2023-12-19

Added

  • PE1RXF telemetry
  • I2C support
  • I2C driver for AM2315 temperature/humidity sensor

Fixed

  • Struct for saving settings to FLASH is now 256 bytes excactly (problem with padding done by the compiler)

[1.1.1] - 2023-12-19

Fixed

  • One of the digital outputs was inverted.

[1.1.2] - [2024-01-08]

Fixed

  • Negative temperature where converted wrong: -1 became -32767. This was because of a weird format the sensor uses.
