/*
|
|
* This is 95% the same code as Michael Farrell's hf_14ASNIFF Standalone mode.
|
|
*
|
|
* `hf_15693sniff` passively sniffs ISO15693 frames, and stores them in internal
|
|
* flash. It requires RDV4 hardware (for flash and battery).
|
|
*
|
|
* On entering stand-alone mode, this module will start sniffing ISO15693 frames.
|
|
* This will be stored in the normal trace buffer (ie: in RAM -- will be lost
|
|
* at power-off).
|
|
*
|
|
* Short-pressing the button again will stop sniffing, and at _this_ point
|
|
* append trace data from RAM to a file in flash (hf_15693sniff.trace) and unmount.
|
|
*
|
|
* Once the data is saved, standalone mode will exit.
|
|
*
|
|
* LEDs:
|
|
* - LED1: sniffing
|
|
* - LED2: sniffed tag command, turns off when finished sniffing reader command
|
|
* - LED3: sniffed reader command, turns off when finished sniffing tag command
|
|
* - LED4: unmounting/sync'ing flash (normally < 100ms)
|
|
*
|
|
* To retrieve trace data from flash:
|
|
*
|
|
* 1. mem spiffs dump -s hf_15693sniff.trace -d hf_15693sniff.trace
|
|
* Copies trace data file from flash to your PC.
|
|
*
|
|
* 2. trace load hf_15693sniff.trace
|
|
* Loads trace data from a file into PC-side buffers.
|
|
*
|
|
* 3. For ISO15693: trace list -t 15 -1
|
|
*
|
|
* Lists trace data from buffer without requesting it from PM3.
|
|
*
|
|
* This module emits debug strings during normal operation -- so try it out in
|
|
* the lab connected to PM3 client before taking it into the field.
|
|
*
|
|
* To delete the trace data from flash:
|
|
*
|
|
* Caveats / notes:
|
|
* - Trace buffer will be cleared on starting stand-alone mode. Data in flash
|
|
* will remain unless explicitly deleted.
|
|
* - This module will terminate if the trace buffer is full (and save data to
|
|
* flash).
|
|
* - Like normal sniffing mode, timestamps overflow after 5 min 16 sec.
|
|
* However, the trace buffer is sequential, so will be in the correct order.
