5 Features of Assembly
5.1 General Features
5.1.1 OS of mobile devices
Above Android 4.4.2 or iOS 8.0
5.2.2 Quick wireless connection and communication mode selection
Received the command of network paring
Wi-Fi module and BLE module start paring operation concurrently
Wi-Fi module stays in paring operation for 30sec, it quits the process automatically if timer is
out
BLE module stays in paring operation for additional 90sec, it quits the process automatically
if timer is out
(Whichever any communication mode is established, the assembly will record the mode flag
(Wi-Fi or BLE) and quit the paring process
Power off the unselected module to reduce the power consumption
