-# BTECH UV Pro Bluetooth TNC Notes
-
-## Linux Packet Configuration
-
-Edit `/etc/ax25/axports` has root and add the following line.
-
-```
-PKT1200 KT7RUN 1200 255 2 145.710
-```
-
-## Radio Configuration
-
-* KISS TNC > Enable KISS TNC = checked
-
-## Pair Radio and Computer
-
-1. On the radio, start the pairing process by navigating to 
-   Menu > Pairing.
-
-2. 
- 
-3. On the computer, run `bluetoothctl`
-
-```
-> power on
-> scan on
-> pair 38:D2:00:00:ED:C8
-> trust 38:D2:00:00:ED:C8
-> quit
-```
-
-## If you're already paired
-
-1. Kill any instances of rfcomm if they are running
-
-```
-sudo killall rfcomm
-```
-
-2. 
-
-```
-$ sudo rfcomm connect /dev/rfcomm0 38:D2:00:00:ED:C8
-Connected /dev/rfcomm0 to 38:D2:00:00:ED:C8 on channel 1
-Press CTRL-C for hangup
-```
-
-3. In another window, check that you are connected.
-
-```
-bluetoothctl info 38:D2:00:00:ED:C8 | grep Connected | awk '{print $2}'
-```
-
-4. Kill any instances of kissattach if they are running.
-
-```
-sudo killall kissattach
-```
-
-5. Attach to the desired AX.25 port.
-
-```
-$ sudo kissattach /dev/rfcomm0 PKT1200
-AX.25 port PKT1200 bound to device ax0
-```
-
-6. Connect to the BBS
-
-```
-axcall PKT1200 TTPBBS
-```
-
-Listen to incoming and outgoing packets and capture the time
-stamps for the traffic.
-
-```
-$ sudo axlisten -a -t
-```
-
-## Troubleshooting
-
-1. systemctl status  bluetooth
