PixMob_waveband reverse engineering

--

the project:

- reverse engineering pixmob RF enabled waveband (868MHz european edition)

got it working thanks to https://github.com/danielweidman/pixmob-ir-reverse-engineering and https://www.hackster.io/abouhatab/reusing-pixmob-waveband-without-flipper-zero-040f3a

the object:

-

• got a waveband labeled "cement v1.1"

• with MCU , EEPROM , RF , two RGB-LEDs and a diode to prevent battery polarity fault

• data is transmitted with a checksum only by RF and encoded with special 6b8b line code to stay in sync.

what we need to get it running:

- hardware:

• arduino
• TI CC1101
• levelshifter (if the arduino is 5V variant)
• ( soic08 clamp: good for development - but the most hardware-work is done)

• connect all together (see connection )

  basic.ino:

• the "basic" arduino script shows how to enable the waveband with an TI CC1101 transceiver and fixed messages

• there is a basic CLI over USBserial@115200: type ? [enter] for help

  play.ino:

• simple programm to play with pixmob batch.

• data is send by basic CLI

  • w\r\n mode byte 1, byte 2, byte 3, byte 4, byte 5, byte 6 \r\n (all hex, 6 bit)
  • f (interactiv)

  content of the Pixmob_cement folder

• copy the whole folder to your arduino sketchbook/libraries folder or download release v0.2.1
• now you can use the pixmob library with example(s)
