how about the CAT.1's power manage, if CAT.1 4G module always connect with ESP32S2 by usb (AEGHB-298)

how about the power consumption of CAT.1 ? if CAT.1 4G module always connect with ESP32S2 by usb.
if no packet communication , CAT.1 will suspend or not ? does the protocol of USB CDC PPP can guarantee the suspend or resume ? does the esp32s2 will send suspend/resume cmd or not ?

1. No power consumption details now, but you can test it on your board.
2. CAT.1 won't suspend in this demo because the USB Bus always in active mode
3. Yes esp32-s2 can use AT to control the 4G Module's power mode, but not implement now. Instead, you can try to use 4G module's POWER and RESET pin to control its power state.
