I know that was November 2019, but in case anyone else sees this, that antenna works with the Proxmark3 RDV4, not the Proxmark3 Easy that Dangerous Things sell.
There are instructions for making a home brew ferrite core antenna for the Proxmark3 Easy on this site, in particular this thread.
Just the lf has stopped working, it was 2 days I think, I was playing with it with the proxmark and it got less and less reliable untill I couldn’t find anything with an ‘lf search’
How long ago was your NExT installed?
The 25th if June
So it totally could be swelling related.
When you first install, there is a little trauma but your body has fully fought back, slowly your body starts to blood pool and swell (even though it is not always obvious from the outside)
Think of the swelling and of reduction of readability like a bell curve.
At the peak and either side you may get intermittent on no reads at all.
(BLUE ZONE from the graph above)
This forum is full of people experiencing the same issue as you, and more often than not, this is the “issue”, It is just your body working correctly
We normally say give it around 2 weeks to be reliable and properly healed
I would still give it another week before you start getting too concerned.
I hope this helps
OR what Amal says down there
this is sorta the key i think… chances are it’s left in a misconfigured state and LF SEARCH will not find anything if it’s not configured perfectly. I would try this;
or… as I like to do… just write an EM410x ID to it a few times and then try LF SEARCH… that can also work to clear a simple misconfig…
ok, so I’m not getting nothing anymore, but I can’t write to it, and it doesn’t turn up on an lf search or lf t55 detect

so it’s getting different data each time you run a dump? it looks almost like noise. how’s your antenna positioning? is someone helping you by pressing enter or are you juggling all that yourself?
PS … just asked iceman if he could add a delay to the search / clone commands…
just a small suggestion that is a serious pain in the ass for a small group of people… adding a delay to any kind of operation would be very helpful. Basically when you are trying to position a proxmark3 over your implant you are typically using one hand to hold the proxmark3 over the other… and then having to use an elbow or awkwardly extended finger to press enter… if a settable delay could be added as a parameter to allow like -d 3 to delay 3 seconds before executing… it would be super helpful. the most important commands of course are the hf/lf search and various cloning commands.
we’ll see what he says.
Yeah, I was juggling it myself, I should figure out a better solution 
Actually he said there’s already a provision for it!
msleep -t 3000; lf search
So basically you issue the msleep command first (in milliseconds) then a semicolon to chain commands together.
i’ve got it in a vice now so I have a free hand, the lf t5 detect command doesn’t find anything so maybe I’ve go the wrong config for the tag?
is the config hard coded or can it be changed using block0? What should I be using?
edit:
I don’t know if this is a good reference, but I’m only getting a 3,000mV drop on the lf tune display with my implant, compared to arround 16,000mV on another tag
but now I can’t write to, or read anything meaningfull from either of my test lf tags
ok, I can’t get a read of either of my test t5577 cards either
One card turns up with an Indala ID that changes every time I run lf search, and the other can’t find a valid tag but detects the t55xx chipset.
I can’t write to either of them using lf t55 wipe, lf t55xx write b 0 d 000880E0 -t or lf em 410 clone --id 0D00072C63
Have I done something to my proxmark?
Time to dive in… what hardware do you have? What firmware? When you launch the pm3 client it spits out some info on the screen… post that too…
proxmark3 easy from you guys (about a month old), windows, used the getting started with the proxmark3 post so: proxspace, iceman repo, reflashed this afternoon just to be sure it wasn’t something to do with that.

Hmm ok well it looks correct… and you’re putting the card on the LF antenna… that’s strange
