Data rate: 115.2 kbps, Data size : 8 bits Parity : None Stop bit : 1 bit In exploitation mode, UART is in charge of exchanging data to transmit (UPLINK), data to receive

(DOWNLINK), + some other internal data and traces (DEBUG, etc..) Before exchanging UART frame, one or several WakeUp character could be emitted by the RTU module. This number of wake up character is configurable (Register S2xx) 1.1.2 RTU signal description 1.1.2.1 Reset signal The reset signal allows a complete reset of the RTU module. 1.1.2.1 RTU ready signal This signal is used to indicate to the host microcontroller if RTU module is ready for reception of new command. When the signal is low, data sent on the UART of the module are ignored. Each time a new command is transmitted to the RTU, this signal goes low until the end of the command processing. After an Uplink command request, RTU Ready stays low for the complete IoT cycle. In that case, the duration may be very long (many seconds). 1.1.2.1 TX Uplink / RX Downlink signals These two signals are signals frame activated at uplink (RF transmission) and downlink (RF reception) during IoT cycle. 1.1.2.1 UART Tx an UART Rx signals These two signals allow UART communication to support the serial interface protocol. UART TX is an output of the RTU module, UART Rx is an input. 1.2 Serial interface protocol This protocol will be used on exchnge from apllication to RTU module and vice&versa. 1.2.1 Command format Frame format little endian LSByte first 1.2.1.1 Command

Configuration

& Test command Figure 9: RTU state diagram Idle and Nominal mode 2.1.2 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.
