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
-
-
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.
- 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 )
- 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
- 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)
