re: ZigBee applications - Part 1: Sending and receiving data

The phrase "A data indication means a node is receiving data from another node" tells absolutely nothing. What does "indication" means ? Does it means receiving data by the node ? If so, where is the "sending data" primitive ? I think we should avoid using terms that are not intuitive, even if they were introduced in OSI model 30 years ago.

Nice book to start of with zigbee..... I have been working on this protocol since a month and have few queries What does it mean by zigbee end devices are in sleep mode most of the time. Is it the the radio is completely shut down or just it is in low power mode like LPM1 in CC2520???? If so if one tries to communicate with the end device and the end device is sleeping acoording to zigbee standard the router or coordinator buffers messages for its child devices but for how long???????? because in this case if one requests data from end device then it will not respond at all and one might require more RAM space and if network is large enough then imagine.... According to beacon enabled networks the end device wakes up at regular interval but what about non beacon mode. Then i have to keep my end device active all the time in non beacon networks which contradicts that zigbee is low power protocol. I have confusion in this concept. regards, har8951

Nice Book! Drew is almost the only one who knows the easy way to explain real ZigBee.

IoT Network Shoot Out
July 16, 1pm EDT Thursday

Replay available now: A handful of emerging network technologies are competing to be the preferred wide-area connection for the Internet of Things. All claim lower costs and power use than cellular but none have wide deployment yet. Listen in as proponents of leading contenders make their case to be the metro or national IoT network of the future. Rick Merritt, EE Times Silicon Valley Bureau Chief, moderators this discussion. Join in and ask his guests questions.
