I am using Q2686 module with external controller. During idle time I am sending wavecom module in sleep mode using at+cpof command and logic low on ON/OFF pin of module.
To wake up module I am just enabling ON/OFF pin and wait for 15 sec. After that I am trying for AT+CCLK? command through controller to get current date and time, but I am not getting any response. where is wrong.
The RTC battery is connected to module .
