Reset/Restart LTE Modem Card mPLS62-W | Thales IoT Developer Community

February 5, 2021 - 11:44am, 999 views

Hello,

we're using the following device mPLS62-W, info provided by ATI command

Cinterion
PLS62-W
REVISION 02.000

Now, we would like to perform a reset of the modem by using the  PERST# line, as described in the document "mPLS62-W_hid_v02.001a.pdf". Unfortunately, putting the PERST# line to low signal for >20ms don't trigger any reset of the modem. At least, the linux driver is not reloaded and the modem interface is present all the time in linux.

Am I right that the restart should be performed in the same way like with the commadn "AT^SMSO" ?

Are there any knonw issues regarding PERST# line ?

Does the modem need to be configured in a particular way for the PERST# line to work ?

Any ideas how to proceed in this situation are appreciated.

Thanks in advance,

Greetings
