The module uses UART interface to exchange messages with user’s equipment, providing convenient and the fast LoRaWAN network access, and one-way data communication in wM-bus T1/C1 mode. 1.1 Feature  Ultra Low-power SoCchipASR6601 embeddedwithoneSub 1Gtransceiver and one ARM STAR-MC1 MCU, supporting 902-928 MHz channels  Embedded LoRaWAN (1.0.3) Class A/C and Wireless M-bus T1/C1 protocols  Easy to use UART interface for communication and configuration  AT command for communication and configuration  Data encryption AES 128  Conforms with CE RED/FCC 15.247 requirements 1.2 Scope This manual applies to firmware version：LoRaWAN1.0.3_wMbus1.0.2-20220101 and later. EWRF 1020MLA Module User Manual V1.0.1 EWRF Technologies Co.,Ltd. 2/22 2 Working Mechanism 2.1 Modes The module has two working modes: transparent transmission and command. （1）The command mode uses AT commands to configure parameters, read status and send data etc.. In the command mode, when sending a parameter configuration or a status reading command, user needs to wait for the module to return "OK" or "ERROR" before proceeding with the next command,otherwise the command may be invalid. When switching from transparent transmission mode to the command mode, the instruction (0x00 0x00 0x00) needs to be input and does not include the terminator "\r\n". （2）The transparent transmission mode is used to send and receive application data. In this mode, there are two kinds of communication, namely the LoRaWAN communication and the wM-bus communication . The LoRaWAN communication requires the module to join the network before it can access the LoRaWAN data services. The two communications can be switched from the AT command mode by inputting the "AT+SWTMD" . 2.2 Power-on/Resetinitialization When the module is powered on/reset (hardware or software reset), it will be initialized. At this time, the module is in the command mode, and the module can be operated through AT commands. 2.3 Parameters stored in non-volatile memory If theuser wants to store the parameters …
