Supports off-network use, no network, direct mutual positioning, liuyun, APRSdroid, LOCUS, Ovi and other APP and supports user independent firmware upgrade.

Operating

They offer a version for VHF and one for UHF the band they call V-segment and U-segment respectfully. It is recommended to select the VHF V-segment option for North America even though UHF is in limited use. VHF has better terrestrial performance.

The standard VHF APRS frequency for North America is 144.390 MHz. There is no standard UHF frequency for North America. APRS is often used to track the location of vehicles or people, such as hikers or search and rescue teams. It can also be used to transmit weather data, such as temperature, pressure, and wind speed, using weather stations connected to the APRS network.

Program the tracker with the software. The software is Microsoft Windows only requiring .NET 4.

Software settings

1. Power on the tracker.
2. Connect the USB cable between tracker and computer.
3. Install USB driver – CH341 chip and find the correct COM port.
4. Use APRS 51Series Setup(version number).exe to program the tracker.

Review

A full review of this device is in progress. Initially the requirement of Windows only programming software that is suspicious in nature, as are all of these Chinese utilities, makes it problematic for Mac and Linux users.

Troubleshooting

Software

Software is Windows only. Requires Microsoft .NET Framework

Last known source for software and manual:

• X1C5 Pro portable APRS tracker Manual
• APRS setting program

For linux users it is not verified if this program can be ran under WINE. If tested and succeed then the process will be posted below in winetricks section.

powers off during use

The X1C5 has a timed power-off feature. When it powers off, it will disconnect. Set it to "never off" in software. Also, it may shut off if the battery voltage falls. Always keep a charger on it.

Conflicts with BRLTTY when connected to Linux host

Also: USB Serial support registered for ch341-uart in dmesg but /dev/ttyUSB0 doesn't appear present or available.

BRLTTY, a program that "provides access to the Linux/Unix console (when in text mode) for a blind person using a refreshing braille display" conflicts with the USB-serial converter chip in the X1C5. The Braille screen reader and devices that use the CH340 (341) based chip will conflict.

Keep in mind that this device is not supported in Linux, however, if you are working on communicating with it in Linux for experimentation you will have to disable BRLTTY on your linux machine. This frees up /dev/ttyUSB0 for serial communication with this device. Using information in USB Device Diagnostics in Linux you can see if the device is detected, and look for errors. Hint: udevadm monitor --udev, dmesg

The BRLTTY service is launched by the brltty.path service. You can comment out or completely remove.

sudo apt remove brltty

CH341 driver for Linux

Kernel support is built into Linux latest distributions have this and support basic communication with CH341.

[] ch341 3-8:1.0: ch341-uart converter detected
[] usb 3-8: ch341-uart converter now attached to ttyUSB0

you can test by connecting with minicom (minicom -s) option (A) and set the serial port and (E) Bps

Serial Device      : /dev/ttyUSB0
Bps/Par/Bits       : 9600 8N1

Hardware flow control to yes and software flow control to no.

What you do from there... you're on your own. No Linux support. If you turn the X1C5 on then you should see the following come up in minicom:

AT+DMOSETGROUP=1,144.0000,144.0000,0,3,0,0 

It is communicating to the PC.

linux, wine, .NET

Documented attempt to run programming software under linux with wine. It was mentioned on a support web site that the software requires .NET 4.0, however, while testing the software on a windows machine it indicated .NET 3.5x.

You will have to install and configure Wine for your distribution. Info here based on Debain/Ubuntu/Mint. . You will have to do Serial Port Access in Wine Troubleshooting.

Identify the serial port for the device. in /dev you should see the following: /dev/ttyUSB0 then identify and inspect the port with the device connected and on.

tty -F /dev/ttyUSB0 -a

to launch the software

wine ./APRS\ 51Series\ Setup\ 20190723.exe

Issue #1: no com ports visible to software. Make sure it exists:

ls /dev/ttyUSB*

Wine serial port mappings are visible in

ls ~/.wine/dosdevices

To override or create a serial port mapping for /dev/ttyUSB0

wine regedit
