I write the Host-Based Card Emulation(HCE) Application to do the mobile payment on my smartphone. I also use nfc-tools library to help me in coding both app on my phone and the reader. When I try to run the code on those 2 devices,both of them can connect together but it gives me the error as show belowed:
org.nfctools.scio.TerminalHandler getAvailableTerminal
INFO: Checking terminal: ACS ACR122 0
DEBUG: org.nfctools.spi.acs.AcsDirectChannelTag - command: FF00000004D44A0100

Moreover, When I see in the log of the application,I found that My Application has a problem to start and run the Host-Based Card Emulation Service too.

Both 2 error are also related?
