## Long description

The MikroTik Gateway RB924I-2ND-BT5&BG77 (KNOT) is a compact IoT gateway and controller with a 650 MHz processor, 64 MB internal memory and support for Narrow Band (NB-IoT) and CAT-M cellular technologies. It provides multiple connectivity options including 2.4 GHz wireless, Bluetooth, two 100 Mbps Ethernet ports with PoE-in and PoE-out, Micro-USB, a NanoSIM slot and an RS-485 serial interface. The device includes DIN-rail mounting and an IP20 enclosure suitable for indoor and cabinet installations.
Advantages
The RB924I-2ND-BT5&BG77 offers low-cost cellular connectivity via NB-IoT and CAT-M, broad operator support, and a small data footprint effective for telemetry and management channels. It converts Modbus to TCP, forwards Bluetooth advertisement packets over HTTPS or MQTT, and can act as a TCP bridge for wired Modbus sensors. The gateway supports asset tracking with Bluetooth tags (iBeacon, Eddystone or other BLE advertisement formats) and includes packet filtering to forward only relevant data. Dual Ethernet with PoE-in/out and DIN-rail mounting provides flexible installation options.
Suitable for
Remote telemetry and sensor data collection (temperature, liquid, energy meters)
Asset tracking based on Bluetooth Low Energy advertisements
Industrial cabinet installations and DIN-rail deployments
Backup or low-bandwidth management channel for networks and vending machines
Bridging wired Modbus sensors to TCP/IP or cloud services
Key specifications

Memory: 64 MB internal
Ethernet: 2 × 10/100 Mbps ports with PoE-in and PoE-out
Wireless: 2.4 GHz Wi‑Fi and Bluetooth (BLE)
Cellular: NB‑IoT and CAT‑M support; NanoSIM slot
Serial: RS‑485 interface (Modbus support)
Interfaces: Micro-USB
Performance: forwarding rate up to 300 Mpps
Mounting: DIN-rail; Enclosure rating: IP20
Antenna gain: up to 1.5 dBi
How to use
Install the gateway on a DIN rail inside the equipment cabinet and insert a compatible NanoSIM with an NB‑IoT or CAT‑M plan. Connect wired sensors to the RS‑485 interface for Modbus communication or attach Ethernet devices to the 100 Mbps ports. Use PoE-in to power the device or PoE-out to power downstream equipment. Configure network, cellular and Bluetooth settings via the MikroTik management interface to enable Modbus-to-TCP bridging, Bluetooth advertisement forwarding via HTTPS/MQTT, or telemetry reporting to your server.
Usage recommendations
Use a low-bandwidth NB‑IoT or CAT‑M data plan for telemetry tasks to minimize costs; enable packet filters to limit forwarded data and verify RS‑485 wiring and Modbus settings before deployment. For outdoor cabinets, ensure the enclosure provides required environmental protection beyond the device's IP20 rating.
