Hi Team,
We have tried to put the device into sleep mode based on the below steps:
- DTR condition: DTR sleep control is enabled with high level. If DTR sleep control is disabled, this
condition can be ignored.
- USB condition: the status of USB is DISCONNECT or SUSPEND.
- AT+QSCLK is configured to 1.
After few seconds the device entered into sleep (By verified from the current consumption), But after few seconds the device is waking up intermediate and consuming some amount power. So kindly help us to resolve this intermediate wake up.
Hi @Arunraj_Natesan
Will there still be network business at this time? You can use CFUN=0 to see if the flow consumption is normal.
Hallo, i am also havin trouble to set the module in Sleep mode via DTR Pin.
The module is only connected via its IO Pins, no USB.
Using a TXS0108 as level converter as in Datasheet, all communication works fine at highest Baudrate etc.
AT+QSCLK is configured to 1.
But DTR Pin on Modem stays 0 when Host setz is high. Seems to me that the EC25 forces the DTR Pin state low. Did I Miss Something? Module DTR Pin is a simple Input? Right? In order to put Modem in sleep mode, do other Module Pins need a certain state?
