Power Saving Mode of PLS8-E | Telit Cinterion IoT Developer Community

June 22, 2017 - 8:26am, 2284 views

The datasheet of PLS8-E stated that there is a power saving mode of the module, which can be enabled by AT command

AT^SCFG="MEopMode/PwrSave","enabled"

The Hardware Interface Description also stated that the typical rating of current consumption of SLEEP mode is around 2-5 mA.

I was measuring the current of the module only and got the result of about 20mA with Power Saving mode enabled.

Then I realized the USB is still connected after I send AT command via COM port. Therefore I have remove from PC and measure it again. However, the result is still 20mA.

It there some steps I have missed, thus the module cant gito SLEEP mode?
