Bluetooth transmitter/receiver Renkforce RF-BTR-210 Bluetooth 5.0, range up to 10 m, LED display

Renkforce RF-BTR-210 is a compact Bluetooth 5.0 transmitter/receiver that adds wireless audio capability to TVs, PCs, speakers and headphones. The device supports operation up to 10 m and features an LED display for mode and connection status. It switches between transmit and receive modes to either send audio from a non-Bluetooth source to Bluetooth headphones or speakers, or receive audio from a phone or tablet and send it to a wired audio system.

Advantages

The RF-BTR-210 uses Bluetooth 5.0 for improved stability and reduced latency compared with earlier Bluetooth versions, while its small footprint makes it suitable for tight spaces. The integrated LED display provides clear indication of power, mode and pairing status. Switching between transmitter and receiver operation is straightforward, enabling flexible use with different devices without additional adapters. The unit’s range up to 10 m covers typical living-room and desktop setups.

Suitable for

• Connecting non-Bluetooth TVs to wireless headphones or Bluetooth speakers
• Streaming audio from smartphones or tablets to a wired hi-fi or active speakers
• Adding Bluetooth receive/transmit capability to PCs and media players
• Temporary audio setups where a compact, portable transmitter/receiver is needed

How to use

Connect the RF-BTR-210 to the audio source or destination using the appropriate cable and a USB power supply. Select the desired operating mode (transmit or receive) using the device controls and verify the LED display for mode and pairing readiness. Put the target Bluetooth device into pairing mode and complete pairing according to on-screen or device prompts. After initial pairing, the unit will reconnect automatically when both devices are powered and within range. For transmit mode, ensure the source audio output level is set correctly; for receive mode, set the connected audio device to the appropriate input.

Usage recommendations

The RF-BTR-210 performs best within clear line-of-sight distances up to 10 m and when obstacles or sources of interference (large metal objects, microwave ovens, dense walls) are minimized. Use a reliable USB power source and compatible audio cables to ensure stable audio transmission. For lower latency in video applications, use devices and codecs that support low-latency profiles where available.
