Gracefull sleep and wakeup mode

[devprofile98]

Hello, Thank you for this great library. Is there any specific sequence of function calls to make the SIM device asleep ( or minimum functionality mode ) and ensure all of the library parts are aware of this?

in my first try, I called lwgsm_set_func_mode(0, ...) but after calling lwgsm_set_func_mode(1, ...), there will be a failed assertion on one of the MQTT semaphore, I wanted to ensure if there is a known path for the sleep mode to work correctly and if it is implemented already or if it depends on how the client has used the LWCELL library.

Thank you very much.

Disabling the functionality is not a modem sleep, it is rather a modem "shutdown" mode. In this mode, everything is closed, even your MQTT connections.

Thank you. but, Can lwgsm_set_func_mode(0, ...) be used in the middle of a program, or is its use restricted to certain points in the code? Are there specific considerations or related function calls that must be respected when using it?

You can call it in the middle, but I don't see a true point of doing it. What's the task you'd like to achieve?

I am testing various options for reducing the power consumption of the SIM modem. We encountered technical issues with the AT+CSCLK command for entering actual sleep mode, so we are exploring the use of minimum functionality mode. According to the documentation, the current consumption for both modes is similar.
