It seems that the module refuse to enter sleepmode, when the GPS module are activated.
Q: Are there any way to make the module enter sleepmode when the GPS are active reading satelites? This is a power consumption issue.

Yes, I think this is a normal event, the GPS is activated, the AP core of the module still needs to work continuously and cannot enter the sleep mode, although the modem of the module has entered the idle state
