During e-I-DRX, it is recommended to use UART interface for data communication, as the use of USB

interface will increase power consumption.

2.4 Power Saving

2.4.1 Airplane Mode

When the module enters airplane mode, the RF function does not work, and all AT commands correlative

with RF function will be inaccessible.

The module can be set into Airplane mode through AT+CFUN=<fun>. The command provides choice of

the functionality level, through setting <fun> into 0, 1 or 4.

 AT+CFUN=0: Minimum functionality mode. Both (U)SIM and RF functions are disabled.

 AT+CFUN=1: Full functionality mode (by default).

 AT+CFUN=4: Airplane mode. RF function is disabled.

The execution of AT+CFUN command will not affect GNSS function.

2.4.2 Power Saving Mode (PSM)

BG600L-M3 module can enter PSM to reduce its power consumption. The mode is similar to power-off,

but the module remains registered on the network and there is no need to re-attach or re-establish PDN

connections. So BG600L-M3 in PSM cannot immediately respond users’ requests.

When the module wants to use the PSM it shall request an Active Time value during every Attach and

TAU procedures. If the network supports PSM and accepts that the module uses PSM, it will confirm the

usage of PSM by allocating an Active Time value to the module. If the module wants to change the Active

Time value, e.g. when the conditions are changed in the module, the module consequently requests the

value it wants in the TAU procedure.

If PSM is supported by the network, then it can be enabled via AT+CPSMS command.

Either of the following methods will wake up the module from PSM:

 A rising edge on PON_TRIG will wake up the module from PSM. (Recommended)
