10 Power save use cases

By default no lower power mode is enabled in NORA-W36 to have maximal performance and response time. In some application power consumption is important and data throughput and latency is not that important. By enabling the low power mode this will slighty change. More power save means more latency can be expected.
Power level 0 (default, no power save) and power level 1 (moderate power save) is supported, more levels may be added in future releases.

The low power level 1 is set using the command AT+UPMPSL=1 see NORA-W36 SIM and AT command manual for more details. There is a limitation that the first AT command after the timeout (default 1 second) can’t be longer than 16 bytes. Note that in power level 1 only 115200 baud rate or lower is allowed.

All low power modes save power automatically and will adjust this depending on the level. When enabled, no further action is required by the host.

The most efficiant power level is Deep sleep which is almost like a power off, no radio communication is possible in this mode.
