TS&RTS will be used for HW flow control when mass data has been sent.. When TQSLK= is set on the module, customer's application can control the module to enter into or exit from the sleep mode through the pin TR. When TR is set to high level, and there is no on-air or hardware interrupt, such as GPIO interrupt or data on serial port, the module will enter into sleep mode automatically.. RI will output an indication signal when activity such as voice call or SMS is coming.
