Hi Dave, I read your post in flomio forum about ACR35 reader to read NFC tag (http://flomio.com/forums/topic/acr35-timing-numbers/). The post mentioned keep calling piccPowerOnWithTimeout() every 5 seconds. I tried it, but failed. I posted this issue to flomio forum as well (http://flomio.com/forums/topic/how-to-set-piccpoweronwithtimeout-with-30-seconds/), but no solution yet. Would you please give me some tips how to implement it? Thanks!
