PART 2: Beoremote_Lookup_Table

//Bang&Olufsen Remote code table

//This table cross reference codes from the BEO4 and BEORemote One

//controllers, some codes are used differently in the two command sets,

//those differences are highlighted in the naming when needed (BEO4...,BEO1...)

//Command Set summary

Now the next step will be to interface with the SDA/SCL signals coming from the IR EYE (Pin 1 and 4) to be able to control also the lights, but maybe to also use the remaining IO ports of the PCF8574 (there are four unused ports apparently, that i could use to commend relays or leds...)

After that, following step will be to interface with the TDA 7315 sound processor with is also I2C device

Then the hard work will begin... the idea is to compare (with the arduino serial port as debugger), the code generated be the BEO4, and a same command coming from a Masterlink or Powerlink data, trying to isolate the codes and build a correct structure for generating those code. I will also refer to the MGLW protocol guide...

Idea is then to remove the processor board from B&O and replace it completely by an Arduino board...

I'm impressed! Who doesn't want to control his B&O home with a B&O remote... :-)

OK, i have put a little video on youtube to show the actual results...

Bien fait Alain!

I am doing similar integration, but since I never liked any remote controls I am focusing more on voice commands and automated integration with iOS HomeKit.

I am currently reverse-engineering ML, listening to the telegram and interpreting it isn't difficult, however pretending that you are a legitimate ML node or moreover lock master is still to be worked out. If you manage to solve/re-work lock managment protocol  faster than I do, fine bottle of champainge from Épernay is on me;)

Yeah!, do you work on the iOS side only or do you also use some arduino or other stuff (raspberry pi, ?), i am currently working on the blink active setup, but once finished, i will send you what i will discover about the protocol... Keep the good work on!

I use RPi and ESP8266

I have a huge problem getting my Beolab5 speakers to turn on when they receive a Trigger signal from my non-B&O receiver. Someone told me its because it needs a 'data' signal as well - which the BEO4 transmits. 

Would it be possible to record this 'data-snippet' with Arduino and then somehow get it to retransmit this data-snippet when I need to send it?
