First step let Ubuntu to see the modem
My bluetooth usb adapter is an old emtec one, Ubuntu 14.04 does recognize it immediately after plug-in in the usb port.
Then I've switched on Mobilinkd TNC2, the blue led started to flash.
The first problem is that the enclosed Ubuntu bluetooth manager does not works with a Bluetooth serial module of the Mobilinkd TNC.
As I try to configure it with the bluetooth manager it request to set a random password on the modem that is not possible.
So install the blueman bluetooth manager:
sudo apt-get install blueman.
Now start blueman and magically it's possible to pair the Mobilinkd TNC and see it as a rf serial /def/rfcomm0
Try to see if the modem is accessible from the serial port with a terminal, like moserial.
The serial port speed should be 115200.
For example in moserial I saw:
== BeRTOS AVR/Mobilinkd TNC2
== Version 126.96.36.1991
== Voltage: 4026mV
Second step AX.25 settingsFirst install the necessary AX.25 packages:
# sudo apt-get install ax25-tools# sudo apt-get install ax25-apps
Then, configure your AX.25 ports to allow you to access the TNC.
sudo vi /etc/ax25/axports:
# The format of this file is:
# name callsign speed paclen window description
packet0 IN3AQK-9 115200 255 2 144.900 MHz (1200 bps) Packet
Pay attention no empty lines are allowed!
Then connect the AX.25 packet0 port to the tnc with the command:
sudo kissattach /dev/rfcomm0 packet0 10.0.1.1
The result is:
AX.25 port packet0 bound to device ax0
With ifconfig you could see a new ax25 port with the ip 10.0.1.1
Then it's time to call for example:
axcall packet0 IR3DG
Now its, possible to point Xastir to the just created port packet0
