RC-RCQ5-XXX - RC-CC1101-SPI-434 Radio Modem - Over The Air Command - Alarm Function - Remote I/O Functionality Multifunction Radio Modem AT Command The RCQ5-XXX module is not just a low-power radio modem, but a complete platform integrating advanced features that make it ideal for automation, remote control, and industrial IoT applications. Based on the Texas Instruments CC1312R chip, it offers a combination of high performance, low energy consumption, and robust channel management. Smart meters Wireless security systems Home and Building automation 6LoWPAN systems Automatic Measure Reading Low-Power Wireless Systems - Low Power Consumption Intelligent energy management, essential for battery-powered devices or environments where operational continuity is critical. AT+WOR_Duration: Allows you to configure the receiver’s wake-up frequency, choosing between 1000ms, 500ms, 250ms, and 125ms intervals. This architecture drastically reduces average consumption while maintaining the ability to receive data promptly. WOR is especially effective in wireless sensor systems, smart metering, and applications where battery life is critical. - Radio Modem with AT Command (Transparent Transmission Protocol) The RF modem is very simple to use and provides a wireless RS232 link with a RF data rate of up to 200kbps (2-GFSK modulation). The module can work also in Long Range Mode (LRM) with a RF data rate egual to 2.5kbps. The transceivers has the functions of a complete radio modem and simply require CMOS/TTL data at the transmit input and the corresponding transceiver(s) output the same data. Preamble and CRC are automatically generated and added to the RF transmission. - Over The Air Command (OTA Command) The module has the ability to manage No. 4 digital outputs and No. 4 digital inputs both locally and remotely (OTA Command) by sending simple AT commands. - Alarm Function With this function, when a digital input change status a message will be transmitted via UART to the remote device : “Alarm_0_1 ” - Remote I/O Functionality Remote I/O functionality, this is a type of transmission bidirectional used in the field of automatic controls. When you enable this, every time the digital input changes state on station A, also the digital output of remote station B it will reflect these states simultaneously and vice versa. Working into European bandwidth : 433/868MHz Available also the version at 915MHz. The hardware is based on the module RC-CC1312R-XXX designed by RadioControlli (CC1312R based from Texas Instruments).

- Radio Modem - Alarm Function RECOMMENDED HARDWARE DESIGN 1) Hardware All unused pins should be left floating; do not ground. All GND pins must be well grounded. Traces should not be routed underneath the module. The transceiver module must be powered from a regulated voltage. It is recommended to keep the power supply line for VCC as short and low impedence as possible. Near the power pins it is recommended to insert a ceramic the decoupling capacitor (100nF). It is recommended to have a copper ground plane under the shielded zone of the module. The ground plane should be unbroken. Board Ground...
