Topic: nfc-eventd hangs while lsnfc works

Hi,

With libnfc 1.4.2/nfc-eventd 0.1.4/nfcutils 0.3.0 I have lsnfc working:

device = SCM Micro / SCL3711-NFC&RW - PN533 v2.7 (0x07)
UID=04ab1759232580
* NXP MIFARE UltraLight
1 tag(s) on device.

whereas nfc-eventd is not. In its default configuration I get outputs of "Polling failed." repeatedly. Examining the source I see that this is from hardware polling so I recompiled with software polling enabled and get nothing:

nfc-eventd 0.1.4←[0m
Connected to NFC device: SCM Micro / SCL3711-NFC&RW - PN533 v2.7 (0x07)←[0m

[then silence]

That seems funny to me as nfc-eventd seems to call into the same functions for software polling that lsnfc calls into?

I have played around with the compilation, compiling libnfc against libusb-compat instead of libusb0.1 and a few other things so I might have broken something there?

Thanks.

Hi,

The same device can not be used at the same time between two (or more) different processes.
