How to put the device in Sleep Mode?

Knowledge Base Serial

Hi there,

I am testing the EC200U-AU with the EVB_V2.2 and getting strange behavior. from the module I already set the command AT+QSCLK=1, so I expect to see the device in sleep mode until the MAIN_DTR or WAKEUP_IN pins are triggered low, but, somehow, the device wakes up without the pins going low. Am I forgetting to configure something?

Thanks,

Did you debug via USB or the main serial port?

I’m debugging via the serial port but observing the behavior with it disconnected. Could this behavior be due to DRX?
