RF tool based on CC1101 module and Arduino Pro Micro 8VMHz/3.3V. Allows using CLI to control CC1101 board over USB interface. Putty or any other serial terminal can be used. It has similar functionality to YardStick One but is cheaper and does not need specialized software. Allows for RF jamming and replay attacks as well. It has RAW recording/replaying function which works exactly the same as in the Flipper Zero. Additional function is Radio Chat communicator
You simply connect your Arduino Pro Micro (Arduino Leonardo clone from Sparkfun) to USB port of your PC and launch Putty terminal to communicate with CC1101 module over USB Serial port ( /dev/ttyACM0 port in Linux, COMxx in Windows).
Also you may connect this device to Android OTG USB port in your smartphone for portable hacking and use USB Serial Terminal application with option CDC driver set to communicate with the device ( app : https://play.google.com/store/apps/details?id=de.kai_morich.serial_usb_terminal ). When using Serial Terminal app on Android first go to the Settings in the app on your smartphone then upper side of the screen select "Send" and then set "Newline" as CR only. It is sending to many characters to the device and extra character of Newline sometimes stops some of commands like "rxraw" for example.

The code uses SmartRC library (modified Electrohouse library by Little_S@tan) which allows to customize ALL transmission parameters in human readable format without using SmartRF studio from TI (CC1101 parameter customization tool). To use it please download following ZIP library from following github link https://github.com/LSatan/SmartRC-CC1101-Driver-Lib and attach it to the script in Arduino IDE.
Arduino Pro Micro board ( ATMEGA32U4 chip ) must support 3.3Volt VCC and 3.3V TTL logic because this is required by CC1101 board, otherwise you will fry CC1101 chip. Please follow this guide to setup your Arduino environment for Arduino Pro Micro board : https://learn.sparkfun.com/tutorials/pro-micro--fio-v3-hookup-guide/all
If you are having issues with uploading the code from Arduino IDE to the board, after pressing "Upload" in Arduino you have to immediatelly short GND+RST pins two times in few seconds. Then bootloader in Arduino Pro Micro will start (common issue) and upload will begin.

If you want to use different Arduino Board, please change pin assignment in the beginning of the source code and adjust size of EEPROM/FLASH for storing recorded data and size of SRAM memory
Example for ESP32 board :
#define RECORDINGBUFFERSIZE 4096 // Buffer for recording the frames
#define EPROMSIZE 512 // Size of EEPROM in your Arduino chip. For ESP32 it is Flash simulated 512 bytes only

First version of this project was presented in this video : https://youtu.be/iPVckkTjsd0 Using Universal Radio Hacker and my CC1101-tool is presented in following video : https://youtu.be/mdkEK_wmWJA
Change log :
08.06.2023 : optimized CLI
- removed unnecessary parameters for commands RX, TX, JAM.
- changed command JAMM to JAM.
- optimized output of RX command - now will print directly hex values with no description when sniffer enabled.
- corrected reaction for CR/LF when using with "Serial Terminal" application on USB OTG port on Android phones
- Added CHAT mode, if you have couple of these devices you may use it as and IRC like communicator on selected band/modulation/frequency/channel...
09.06.2023 : added RAW mode as in Flipper Zero
- rxraw "interval microseconds",
- recraw "interval usec",
- playraw "interval usec",
- showraw - for record & replay attacking.
- buffer of 1536 bytes is used to store recording (in ATMEGA32U4, 1024 for Atmega Mega/Uno/Nano, 4096 or more for ESP32 boards).
- after playing with RAW mode please always enter "init" command to restart CC1101 chip. Don't worry about Low Memory warning during Arduino compilation it will work JUST FINE.. Enjoy :-)
10.06.2023 :
- added Arduino Mega/Nano/Uno version which requires TTL logic converter for 3.3V - TXS0108E.
- added ESP32 version.
- changed RECRAW command to start recording RAW signal once something appears over the radio.
- added command ADDRAW to enable manual composition of the signal in the buffer (by copying hex number chunks from Universal Radio Hacker tool for example).
- added option SCAN to find a peak frequency for recording/jamming..
17.06.2023 :
- added SAVE function to store recorded frames buffer into non-volatile EEPROM memory of the Arduino chip
- added LOAD function to restore recorded frames from non-volatile memory and put them into recording buffer for replaying.
- added SHOWBIT command to display RAW data from the buffer as stream of bits.
- corrected ESP32 version which has problem with changing (char *) type to (byte *) due to different C++ compiler for ESP32 boards
18.06.2023 :
- updated bit storage order in PLAYRAW, RXRAW, RECRAW commands to match the type used in Universal Radio Hacker tool : https://github.com/jopohl/urh
30.06.2023
- added debug message during CC1101 startup
- corrected EEPROM usage for ESP32 chip based Arduino - ESP32 has 512 bytes, ESP8266 has 4096 bytes
- added ESP32-WROOM version ( I have tested it succesfully with my own board )
- added ESP8266 - WEMOS D1 Mini version
08.07.2023
- corrected ESP8266 version, WDT watchdog restarts MOSTLY solved (this single core chip is heavy loaded with internal WiFI procedures and TCP IP stack). Code was successfuly tested on WEMOS D1 MINI clone and D-SUN CC1101 board. The advantage of using WEMOS D1 MINI biggest size of FLASH simulated EEPROM for RF sequences storage. ESP32 chips are dual core and my code runs better.
13.07.2023
- changed default data rate for Packet Mode from 1.2Kbaud to 9.6Kbaud which removes problems with Watchdog Restart on ESP8266 board and improves stability
27.07.2023:
- rp2040 board added
18.08.2023:
- added command BRUTE for brute force attack on some DIP switches based garage gates. Sometimes the code hangs after executing full brute force cycle. Trying to find the root cause... Another bad news is that I have reached full FLASH capacity of ATMEGA32U4 so no more extensions are possible to the code for this chip.
02.09.2023
-
WIFI client mode for ESP8266 board added - there is a separate source code version wifi in the name. Before uploading the code you need to assign an IP address to the module , put correct default gateway as well as configure SSID of your WIFI router and the WIFI password in the code like below (defaults are for Android tethering access point). Wifi client mode can be used to extend widely the range between CC1101 device and you PC/smartphone which is used to control this board. Beetween them you have external Access Point that will be "man in the middle" to extend the WIFI range...
-
The ESP8266 board connects to your WIFI router/access point (you need 2nd mobile phone which will serve as an accesspoint for your own phone and ESP8266 board) and you do a TELNET to its IP address 192.168.43.100 from the other smartphone :
IPAddress ip(192, 168, 43, 100); // Local Static IP address
IPAddress gateway(192, 168, 43, 1); // Gateway IP address
IPAddress subnet(255, 255, 255, 0); // Subnet Mask
const char ssid[] = "AndroidAP"; // Change to your Router SSID
const char password[] = "password"; // Change to your Router Password
Example scenario for WIFI / telnet connection when ESP8266 is WIFI client :
ESP8266 + CC1101 WIFI client at 192.168.43.100 <-> Smartphone #1 wifi tethering / wifi access point at 192.168.43.1 <-> Smartphone #2 WIFI client / Connectbot - telnet to 192.168.43.100.
ATTENTION ! When using WIFI versions I recommend to set ESP8266 CPU speed to 160 MHz : in arduino IDE - go to Tools, in dropdown list select "CPU Frequency 160MHz" instead of "CPU Frequency 80MHz".
08.09.2023
- WIFI Access Point mode to ESP8266 board added - there is a separate source code version with wifi-ap in the name. Before uploading the code you can change an IP address to the module and SSID for your ESP8266 board. Default is SSID "cc1101" and IP address for telnet "192.168.1.100". This is the simplest scenario, use Connectbot and Telnet protocol to connect to CC1101 board over TCP port 23. ATTENTION ! When using WIFI versions I recommend to set ESP8266 CPU speed to 160 MHz : in arduino IDE - go to Tools, in dropdown list select "CPU Frequency 160MHz" instead of "CPU Frequency 80MHz".
22.11.2023 Corrected bug in showbit() function, all the thanks go to jps1x2.
08.02.2024 Corrected bug in scan() function (not accepting MHz fractions in frequency range), all the thanks go to chris4soft
Known Bugs : sometimes RX command does not work correctly after many big frames have been received (in packet mode, not in async mode). This may be due to some memory leak in SmartRC library. Still checking what is the reason. Keep attention to putting an argument to rxraw, playraw command - otherwise ESP8266 are restarting themselves when wifi in use (stack overflow).
