Hot plug / hot swap

Dear community,

    I couldn't suceed in getting PM3 recognized when pluggin it back while it still powered.
    I was wondering if some of you tryed and succeed and would be able to share some experience feedback ?
    And if not I does anyone knows what kind of topic this matter shall be aressed to ? (hardware ? software ? drivers ?)

   My test was based on a snoop / sniif action :
       1) Plugging the PM3 (with a battery also plugged - autonomous / standalone capable)
       2) Launcing client
       3) hf mf sniff (or hf 14a snoop)
       4) unplug
       5) do some tests
       6) plug
       7) hf list raw  (or hf list 14a)


   I never can pass trough step 6...
   Either ''sending bytes to proxmark failed'' or system can't detect card (and then i need to power it down and plug it back)
   On all case, my issue is that i loose all data and history  sad

   Any piece of advice are thanked and welcomed ;-p

Re: Hot plug / hot swap

After "5" you need to press the button to stop snooping.

Re: Hot plug / hot swap

Hello Asper,

     You're right if forgot the step ''push button" (between 5 and hf list or 6 for unplugged)
     While trying connected i can read
          #db# cancelled by button                 
          #db# COMMAND FINISHED                 
          #db# maxDataLen=3, Uart.state=0, Uart.len=0                 
          #db# traceLen=5505, Uart.output[0]=00000026

     I've tested with new rc2, plugged behavior seems ok (orange + red light goes off once button is pushed)
     Nevertheless, when unplugged, red light stay lit when I push the button


    sad    From your answer I guess it is working succefully while unplugged for you...    do you think it can be my hw  ?   sad
