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)

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.
