"Blew circular buffer" error while trying to sniff for ISO14443A communications.

[KVM1L]

I'm getting this error when I try to "hf 14a sniff":

pm3 --> hf 14a sniff
#db# Starting to sniff
#db# [!] blew circular buffer! | datalen 231
#db# maxDataLen=231, Uart.state=0, Uart.len=0
#db# traceLen=0, Uart.output[0]=00000000

After error the blue LED on my Proxmark3 gones out. My hardware configurations:

pm3 --> hw version

Let me suggest you use https://github.com/rfidresearchgroup/proxmark3 for you device and see if you still have a problem.

Meanwhile I will close this issue. Open a new in RRG repo if needed
