Ok, so there is no power saving when I use the 5 V pin, can I use some other pin on the M5 COM.NB-IoT module to be able to achieve power savings when using PSM or eDRX ?

Hi

I connect an amp meter between the 5V pin in the M5 module and the 5V supply.
I run the AT command AT+CPSMS=1,,,"01000101","00100010"
I get the message after one minute that power save mode is turned on.
but the current stays on 10mA, no reduction.

Anyone see what I am doing wrong ?
