+It is possible to use modem **in client mode** with other generic Linux AX25/APRS tools on PC or Raspberry, such as [Xastir](https://xastir.org/index.php/Main_Page), use next procedure to set it up:
+- AX25 howto: http://tldp.org/HOWTO/AX25-HOWTO/
+- Install required tools: ```sudo apt-get install ax25-tools ax25-apps xastir bluez bluez-tools```
+- Run bluetoothctl and pair with the modem: 
+  ```
+  # bluetoothctl
+  [bluetooth]# agent on
+  [bluetooth]# default-agent
+  [NEW] Device 01:02:03:04:05:06 loraprs
+  [bluetooth]# pair 01:02:03:04:05:06
+  Attempting to pair with 01:02:03:04:05:06
+  Pairing successful
+  [bluetooth]# exit
+  ```
+- Run `rfcomm` to setup serial over Bluetooth at `/dev/rfcomm0`: `sudo rfcomm bind 0 01:02:03:04:05:06`
+- At this stage you can already start using `xastir` or any other application, which can operate over KISS Serial TNC
+- You can setup `AX25` network interface with `sudo kissattach /dev/rfcomm0 ax25` command, but previously need to update `/etc/ax25/axports` with new line as `ax25    CALLSIGN-10        9600    255     1       comment`, you can also specify IP address if there is a need to run TCP/IP over AX25
+- Run `axlisten` to capture incoming and outgoing traffic as `sudo axlisten -a`
+- Use `beacon` utility to send custom packet as 
+  ```
+  # sudo beacon -s -c NOCALL-7 -d "BEACON WIDE3-3" ax25 "beacon over lora"
+  # sudo beacon -s -c NOCALL-7 -d "CQ WIDE1-1 WIDE2-1" ax25 "anyone on lora?"
+  # sudo beacon -s -c NOCALL-7 -d "APZMDM WIDE1-1" ax25 "!0000.00N/00000.00E#test position report"
+  ```
+- Connect to another client as `sudo axcall -s NOCALL-1 ax25 NOCALL-10`
