Arduino Bluetooth AFSK1200 TNC Modem

====================================

Arduino Nano/Uno Bluetooth KISS AFSK1200 TNC based on customized version of LibAPRS.

Introduction

------------

Arduino bluetooth TNC modem is based on customized version of LibAPRS, allows 

simultaneously work using both bluetooth and USB-serial port. Uses next

peripherals:

 * 👍 Micromodem shield for Arduino Nano - https://oshpark.com/shared_projects/NjA5xkC7

 * or Micromodem from marqvist - http://unsigned.io/micromodem/

 * Bluetooth serial adapter HC-05/HC-06

⚠ For packet decoding requires additional RC filter on speaker line to overcome handheld transceiver pre-emphasis. Also, requires additional single power wire to trasnsciver battery for power.

Building

------------

Use platformio to build and upload.
