Hi there, I have few questions about my arduino project. I have to control 11 lights by using a tx module with buttons on it. Lights should be lit up simultaneously and without any delay. I have zigbee s2c modules and planning to use in api mode star configuration. Which firmware should I flash my xbees IEEE802.15.4 or zigbee th for the best results? Also I downloaded the api library for arduino andrewapp did the setup properly but it gave me the error "xbee does not name a type" what could be wrong about it? Finally Can I do this project on the coding side by using serial.read/write commands ?
