Radiocontrolli WIRELESS MODULES Lora Transparent Transmission Protocol RC-RICK-XXX is a radio modem with UART interface usable with AT commands for long distance communication with LoRa modulation (LoRa Transparent Transmission Protocol). Working into European bandwidth : 868MHz The hardware is based on the module RC-WLE5-XXX designed by RadioControlli (STM32WLE5Jx based). For more information and details, please refer to : Module Information : 868MHz standard Version (UFL Connector) Helical Antenna Version The module is designed to be easily integrated into your hardware application, we provide 2 versions: 1) Standard version with UFL connector You can use the UFL connector where you can directly connect the antenna. 2) Version with helical antenna (full version) Applications: • Smart meters • Wireless security systems • Home and Building automation • Automatic Measure Reading • Low-Power Wireless Systems Wireless Sensor Networks Remote Control Street Lights System Parking Sensors Environmental Sensors Smart Grid and Automatic Meter Reading Radiocontrolli s.r.l refuses any responsibility for irregular uses of the devices and for any possible lack or inaccuracy of the data and reserves the right to change in whole or in part these information without notice.

RC-RICK-XXXTECHNICAL CHARACTERISTICS Characteristics The module is based on STM32WL5Jx device which integrates : - Sx126x LoRa transceiver on the same chip.

RC-RICK-XXX RC-CC1101-SPI-434 PINOUT UART RX Standard Version Reset Trigger Input (Active pull down). Supply Voltage Using this pin it’s possible to updated the FW version. In normal operation this pin must be GND. . Make this pin at 1 (3Volt) when is necessary to proced with the firmware update. WakeUp Low-active When the module is in sleep mode, it’s possible to pull down (50ms) this pin to wake up the module.

Note : Make sure in the shadow area shall without any wiring or ground. Pag. 4 / 32 Rev 2.4

RC-RICK-XXX Wk W WIRELESS MODULES The AT commands are used to drive the LoRa module and to send data. AT commands are sent through the UART peripheral. Serial Port parameters: • Parity: none • Flow control: none AT command is based on ASCII code.

Radio(((ontrolli WIRELESS MODULES AR+Sleep entry low power mode AT+SLEEP means that both BB (BaseBand) and SF enter the lowest power consumption state. After this command the module will no longer respond to any AT command, it will be necessary to use the wake-up pin to return to the previous conditions. * Radiocontrolli s.r.l refuses any responsibility for irregular uses of the devices and for any possible lack or inaccuracy of the data and reserves the right to change in whole or in part these information without notice.

RC-RICK-XXX ■t W WIRELESS MODULES The above figure is a polling sequence diagram. We want slave id:9 to return the status (but there is no slave id:9 in this network) At this time, after the master waits for 2000ms in the RX state, it will close the RX state.

RC-RICK-XXX1-AT Command (Radiofrequency Command) Description AT+Standby switch RF to standby mode AT+Standby means to switch the state of RF layer to idle state. When the RF layer is in the TX or RX state, if I want to interrupt the current TX or RX state of the RF layer, I can use AT+Standby to make the RF enter the standby mode. AT+Standby means that AT+Standby enters the lowest power consumption state, but BaseBand can still receive AT commands.
