USB-1100PA 433MHz Wireless RF Transceiver

RF Transceiver

I recently ordered myself a 433mhz USB transceiver. After a few weeks waiting the package arrived from Hong Kong containing a 433MHz USB transceiver… unfortunately the package lacked any manual or driver. The device itself contains only a marking stating “RF Transceiver” but nothing more, no serial number, no vendor name, nothing.

I run Ubuntu on most of my machines and none of them seemed to support the device. My windows Vista box (I know) recognizes the device as I/O device, but nothing more then that, ideally it would be registered as a terminal device so I could talk to it, but nothing.

I’m currently still searching for a good way to get things working, but as I found nothing on the net to help me in my search I thought I would make this little write up so it could help others in their quest to get this device working.

TLDR: Here’s what I found so far.

The ‘specs’ from the reseller’s website:

  • CC1101 chipset
  • 433MHz ISM frequency range
  • Transmit speed: 250Kbps
  • High efficiency MSK modulation
  • Working range: 300~400m in open area
  • Applications: PC to PC data transmission; Build PC to electronic devices wireless remote control system

From the chip itself
NetUSB  1101PA20DBM U3

From a Chinese reseller’s site (yeay google translate)
[Module] NewMsg-NETUSB-1101PA20DBM,
The USB-1100PA wireless communication module, TI-Chipcon CC1101 chip as the main chip,
real USB interface, compact, containing exquisite shell internal amplifier circuit,
remote wireless transceiver can be achieved, suitable for computer wireless remote wireless data collection.
Can easily build a PC-based long-distance wireless communication system

Current Status

By searching the developpers site for USB1100PA you can locate a chinese ‘manual’, it contains references to a windows based terminal emulator that should be able to talk to the device. I guess reverse engineering this will be my best bet.

Before I started looking around on the net I started of playing with python to talk to the device. It seems to expose only one interface and only two endpoints, one Read, one Write. But I haven’t gotten much further then making the devices light burn. As I have only one device I can’t really tell if it is sending out data or if the reading functionality actually ‘reads’ correct data.

I’ll update this post as I go along. If you have anything to contribute, please leave a comment.


The , what I think is the vendor, site has the following manual: (pdf download at the bottom)

This specifies the cp210x driver for Vista. , so I followed the procedure as described at

  • apt-get install build-essential linux-source
  • cp /usr/src/linux-source-3.5.0.tar.bz2 /tmp
  • cd /tmpbunzip2 linux-source-3.5.0.tar.bz2
  • tar xf linux-source-3.5.0.tar
  • cd linux-source-3.5.0
  • cp drivers/usb/serial/cp210x.c drivers/usb/serial/console.c.orig
  • #add product
  • gedit drivers/usb/serial/cp210x.c
  • make oldconfig
  • make prepare
  • make scripts
  • cp /usr/src/linux-headers-3.5.0-22-generic/Module.symvers .
  • make -i M=./drivers/usb/serial
  • cp /lib/modules/3.5.0-22-generic/kernel/drivers/usb/serial/cp210x.ko /lib/modules/3.5.0-22-generic/kernel/drivers/usb/serial/cp210x.ko.orig
  • cp drivers/usb/serial/cp210x.ko /lib/modules/3.5.0-22-generic/kernel/drivers/usb/serial/cp210x.ko
  • modprobe cp210x
  • #reboot
this resulted in (extract from dmesg)

    I bought same and I have also same experience. I want to use it with FHEM (, because I have NAS, which will be ideal for this task. But I can’t run it in Windows for testing. It still connecting only over USB, but I need it connect to via virtual COM port, but still without success. If you find any information, so send me email, please :-)

    I have just ordered one of these, anyone got it working with .net?

    Did anybody get it working? Mine doesn’t even get detected with this hack.

    Modinfo shows device id, so the right driver ist loaded:

    Got the driver finally loaded to recognize the device (dev/ttyUSB0) with this manual:
    Unfortunately i have the “cp201x_open – Unable to enable UART” issue now.
    I extended the TIMEOUT in the driver to 5 secs. but still get the messages.

    Was anyone able to get this working?
