Introduction

TLKCore is a core service which inside the TMXLAB KIT(TLK/WEB-TLK), it integrates Python built libraries which developing mmWave( n257 / n258 / n260 / n261 ) beamforming and beam steering applications on BBox 5G Series(mmwave beamformer) and UDBox 5G Series(mmwave Up-down frequency converter) and other standard products developed by TMYTEK.

The .pyd format release is for Windows shared library and .so format release is for Linux shared library. Python is a cross-platform programming language, and we provide the basic Python example for all devices/platforms in the release package, and C/C++ examples for Linux platform in C_Cpp folder. Please refer to the sample code inside each folder for the specific programming language.

Architecture

Hardware

• TLKCore is running on Windows/Linux PC, to communicate with standard products developed by TMYTEK via Ethernet/ComPort/USB cable.
• (Optional) FBS part is optional solution to control BBox 5G series as fast beam steering.

Software

• TLKCoreService is a entry point for developer, all of operations/functions must passed by TLKCoreService, e.g. scanDevices(), initDev().

• TMYCommService is maintaining physical communications for all devices, it usually not handled directly by developer.

• TMYUtils defines all data structure for return data, let developer more easier to know current status of processed function.

• TMYPublic is a open source code, it defines all data structure which developer might used, e.g. RFMode(TX/RX), RetCode(OK/ERROR/...), UDState...etc.

• (Optional) TMYBeamConfig is option solution for FBS (fast beam steering), it aims to parse assigned csv file to a dict structure and check beam configuration, please reference FBS

• All files/function under tmydev/ are all operating logic of standard products

• db/ used for WEB-TLK, developer could ignore it.

Prerequisites

Python 3

• Install Python 3.6 or 3.8 or 3.10 which mapping with TLKCore_release, and follow reference user guide of Getting Started with Python Sample Code to make sure your Python environment first.

Communication environment

Host PC can communicate with TMYTEK product through physical connection as the following items, most of products using Ethernet/RJ-45.

Ethernet/RJ-45

• DHCP - Put the device and host PC in the LAN.

• Static IP - Configure your network environment to IP: 192.168.100.xxx, and Subnet Mask Bits <= /24, likes: 255.255.255.0

  

ComPort

• Windows
  • Launch Device Manager
• Linux

  1. lsusb to check your device.

  2. Create or extend /etc/udev/rules.d/99-tmytek-usb.rules including:

     SUBSYSTEM=="tty", ATTRS{idVendor}=="1a86", ATTRS{idProduct}=="7523", GROUP="plugdev", MODE="0666"
     SUBSYSTEM=="tty", ATTRS{idVendor}=="2341", ATTRS{idProduct}=="0043", GROUP="plugdev", MODE="0666"

  3. To add blacklist of ModemManager, please create or extend /lib/udev/rules.d/78-tmytek-usb.rules including:

     # Overwrite to 77-mm-usb-device-blacklist.rules
     
     ACTION!="add|change|move|bind", GOTO="mm_usb_device_blacklist_end"
     SUBSYSTEM!="usb", GOTO="mm_usb_device_blacklist_end"
     
     # TMYTEK's PD
     ATTRS{idVendor}=="1a86", ATTRS{idProduct}=="7523", ENV{ID_MM_DEVICE_IGNORE}="1"
     ATTRS{idVendor}=="2341", ATTRS{idProduct}=="0043", ENV{ID_MM_DEVICE_IGNORE}="1"
     
     LABEL="mm_usb_device_blacklist_end"

  4. Try to reload udev rules.

     1. sudo udevadm control --reload-rules
     2. sudo udevadm trigger
     3. Re-plugin com port device.

USB (Optional)

Install USB driver if scan interface includes DevInterface.USB -> Installation Guides for all platforms

• Windows
  • Online-Host with external internet capability
    • Auto detect a new device and install driver
  • Offline-Host
    • Download setup executable driver from FTDI and install it.
• Linux

  1. lsusb to check your device.

  2. Follow steps to create or extend /etc/udev/rules.d/99-tmytek-usb.rules including:

     SUBSYSTEM=="usb", ATTRS{idVendor}=="0403", ATTRS{idProduct}=="601c", GROUP="plugdev", MODE="0666"

  3. Try to reload udev rules or re-plugin USB devices.

     1. sudo udevadm control --reload-rules
     2. sudo udevadm trigger

Troubleshooting

1. I called scanDevices() but can not find my device via Ethernet.

   • [Action] Please check the following steps
     1. Make sure your physical connection, PC-device or PC-Router-Device...etc.
     2. Make sure your network setting.
     3. Check your firewall disabled, if you must enable firewall, please enable outgoing/incoming UDP or enable whitelist UDP ports: 5025, 7025-7040
        • Windows
          • netsh advfirewall firewall add rule name="Allow UDP out" protocol=UDP dir=out localport=5025 action=allow
          • netsh advfirewall firewall add rule name="Allow UDP in" protocol=UDP dir=in localport=7025-7040 action=allow
        • Ubuntu
          • sudo ufw allow 5025/udp
          • sudo ufw allow 7025-7040/udp
        • CentOS
          • sudo firewall-cmd --permanent --add-port=5025/udp --add-port=7025-7040/udp
          • sudo systemctl restart firewalld

2. Where is my calibration table or antenna table(AA-Kit)?

   • [Action] They shall put on your USB FLASH, copy them to files/.
