XP Deus wave form on oscilloscope

[petere]

Hi
I have just made a quick video showing the waveform of a XP Deus 9" search coil using 4kHz
So for all you people who lay awake at night wondering what the waveform looks like you can now put your mind at rest.

Yes, inductive coupling.
I was talking about that on the other topic.
(but nobody listen)

Nice work! By the way I'd be very interested to know what is transmitted between the coil and receiver, as far as I know Deus uses a nRF24L01 transceiver. Cheap (4$) breakout boards with a UART interface can be found on ebay, I would even sponsor one

Thanks but I think that may be beyond my capability.

One thing is for sure; it is not standard BT protocol.

One thing is for sure; it is not standard BT protocol.

RF protocol is a proprietary from Nordic Semiconductor, however there's no encryption - except if it's implemented manually on the application layer.
It's possible to intercept the traffic with another nRF24L01 receiver - the output comes over an SPI interface, application protocol is for sure custom but can be learned.
