Integration Guide, Version 1.6

3.6 Turn ON using command

When being in sleep mode, the receiver module will be automatically wake up after the CPU

senses a state change in the TD1 pin. The first data byte is lost because the CPU UART is shut

off, and is not able to read data.

To turn the module ON from modes sleep1 or sleep2

1) Issue a state change to DT1 (toggle pin (minimum pulse duration time 10 µs) or issue a

byte on the UART (for example 0x00))

2) Wait for “OK” -response from the module

3) Start communicating normally

Module will remain powered ON until a new sleep command is issued.

3.7 Turn OFF using command

Two control commands are available for putting the device into different states of power save

mode. (see SL-list).

3.8 Turn OFF using pin

The module can be shut down by driving ENA_IO line to <0.2V.

In the “OFF” state current consumption is only that of leakage current from a LDO (xx uA).

In this state all non parts off the module are powered down and all settings / state information

that are not stored in NVM is reset.

3.9 Restart

After startup the module can be restarted by issuing a SL command, upon which the module will

shut down all circuitry, and Reboot the CPU. (see SL-list)
