Hi guys!

I bought the MTX deluxe control, by email the xylobands.com team informed me that the control would not work with the bracelets we won on the Coldplay show, since these wristband responded for a different frequency but we could send the bracelets to them because they would record a new frequency on the bracelet!

I asked how they did it, they said there is a control that records the frequency, but they did not market that control.

My question is, how can we record this frequency? Does anyone have any ideas ?

I am sorry, but with the current information we have reversed from the packet records we would not know which command could be sent to change the frequency band of the band.

I think I remember seeing a small switch for changing the frequency band on one of Xyloband's images of one of their transmitters. Have you checked whether there might be such a switch on your MTX?

More general, not with regard to your problem:
What skills in electronics do you have? Would you be able to capture SPI dumps of the internal SPI bus of the MTX? So we could know which packets are sent when pressing which button. This could help us further reverse engineering the protocol.

Kind regards,
Stefan

Band is controlled by tiny Atmega controller and this is what defines receiver's frequency.
