PLS8-E: PWR_IND does not work as intended before first start [SOLVED] | Telit Cinterion IoT Developer Community

I have finally solved this issue.
WAKEUP from modem were connected to a GPIO not setup correctly so instead of an input it was undefined and happend to be high. Which caused some modems, but not all to act a bit crazy. PWR_IND went low as soon as WAKEUP went high. But after a start sequence on IGN, PWR_IND acted as expected when powering the modem both on and off.
I have seen that on some modules the PWR_IND signal does not work as intended.
I have to start the module once and after that PWR_IND works as expected.
PWR_IND is connected as the hardware interface description specifies.
Have anyone seen this? Is there a fix? Maybe even a firmware update that fixes this?
This issue was already reported to Gemalto customer support by your distributor and is being investigated. There is no conclusion available yet.
You have currently the latest firmware for this revision.
Updated with solution.
