Capture raw data from radio and play it back

I have a device that I would like to add some features to.  I took its remote apart and found the chip to be N52832.  I bought an Ubertooth One and scanned while pressing buttons on the remote for BT / BLE and got nothing.  Using the spectrum analyzer, I found very high spikes at 2453 Mhz (channel 51?) when pressing the remote buttons.  

I bought a DK from DigiKey that has the 52832 chip.  I was hoping it would be possible to just grab the data from the air and do a replay "attack".  The remote is very simple and I'm hoping that once the remote has been paired to the device that it always sends the same code.  Or at least, that if I replay it, it will do what I want.  

is it possible to do what I'm wanting with the 52832 chip?  I'm fairly tenacious, but if someone a lot smarter than me tells me it won't work with the tools I have, I'll have to find other tools.

I did find this page which gives me hope:  https://infocenter.nordicsemi.com/index.jsp?topic=%2Fcom.nordic.infocenter.nrf52832.ps.v1.1%2Fradio.html

I really need to know if what I'm attempting is not possible, but If anyone thinks it is possible, and wants to give me a leg up:

  I need to figure out how to tell the radio I only care about 2453 Mhz

  Read raw packets from the radio - log to output

  Write packets back to the radio.

I'm using Windows and was able to get the nRF Sniffer, Blinky samples and RSSI viewer all working (obviously not at the same time :))

  • Hello Loucks,

    For BLE protocol 2453 MHz frequency is not for advertising. Channel 37 (2402 MHz), channel 38 (2426 MHz) and channel 39 (2480 MHz) for BLE.

    It seems like the device you are tying to scan the information from is not using BLE protocol. May be it has some other protocols. Sorry we can not help you with reverse engineering other protocols and sniffing the data as we do not know what has been used. If the data is secured or not. Theoretically what you intend to do is possible; might be some other forums would be more suitable for ask. 

    Thanks.

    Best Regards,
