In response to dipak's post in the "speaker model" forum, I recorded the SPI traffic on powerup for my unit. My unit is from the Chicago, IL, U.S. concert so I think we all expect some different radio configurations compared to European units. I don't know anything about the Si4362 (or any radio, for that matter), so I'm posting this here in case anyone else can understand the differences before I finish researching the part. Here's the stuff: Raw data: xylo5-c_SPI_powerup.txt (2.89 KB) Spreadsheet (copied from dipak's) showing differences on mine: xylo5-c_SPI_powerup.xls (38.5 KB) (differences are highlighted on the second tab)

Also, I confirmed the same traffic occurs on a xylo5-c from the Rose Bowl, Los Angeles, California, US concert (I got 3 of those on eBay to add to my 1 from Chicago).

ayelix,
The data that you have provided for the US version of the Xyloband shows differences in the address range 4000 to 4005. This corresponds to a radio frequency of 454.6 MHz (the European version uses 869.5 MHz). There are some other differences which you have highlighted and I do not know what these are, but I suspect they may be related to the radio frequency.
Hopefully this will be useful if you want to make a radio transmitter. The next step will be to work out the data protocol and a lot of work has already been done by Stefan and progman who have contributed in other sections of this forum.
