How to manage modem communicatioon ?

[Achevillard]

Hi,

I'm working on a custom board with a nrf9160 µC. This board is powered by a battery and a supercapacitor and my job is to assure the autonomy of the battery.

I would like to limit the modem period of activites to let the scap recharges before a new modem activity.

I have set PSM mode when the modem is sleep. But sometimes, the modem wakes up when I am measuring the voltage of my scap.

Need I to use AT+CFUN=0 or AT+CFUN=4 to deactivate the modem activity ?

Is there another solution to prevent the modem activites without stoping the modem and loosing the advantage of PSM mode ?

Thank you by advance

Hello,

I will get back to you on this. Note that we have entered the summer holiday period in Norway so staffing is low, some delayed response time should be expected.
