Idle and Nominal mode 

At powerup or after a reset or the module enter idle mode. To allow IoT communication, the host controller must 
send the Start RTU command (command code 0x01). In these states, the module reaches ultra low power 
consumption while there is not command processing. The module is automatically wakeup by the char received 
on its UART and returns to standby mode after the processing. 
 

2.1.3

 

Command mode 

Command mode is the configuration and test command state of the RTU module. Command mode may be 
entered from Idle mode or Nominal mode by sending the Enter Command Mode command (command code 
0xFE). In this mode, the RTU is not standby so there is no power saving while the module stays in this state. The 
command format is based on AT style command which is an ASCII oriented format.
