Pin definition : * PIO8 connects with LED cathodea with 470ohm series resistor in between. LED NEGATIVE connects to ground. It is used to indicate the module state. After powered on, flashing intervals differ in different states. * PIO9 is used to control LED indicating paring. It will be steady on when paring is successful. * PIO11, module state switching pin. HIGH -> response to AT command; LOW or floating -> regular work status. * With build-in reset circuit, reset is completed automatically after powered on. * Steps to set to MASTER: * Set PIO11 HIGH with a 10K resistor in between. * Power on, module comes into AT Command Response Status * Open HyperTerminal or other serial tool, set the baud rate 38400, 8 data bits, 1 stop bit, no parity bit, no Flow Control * Via serial port, send characters "AT + ROLE = 1 r n",if successful, return "OK r n", where r n is carriage return. * Set PIO11 LOW, re-power, then in Master state, automatically search for slave module and connect. ## Features - Compatible with Arduino, Stamp, FPGA, AVR, PIC, ARM, MSP and more! - After pairing when full duplex serial port to use, support from 1200bps ~ 1382400bps - Coupled Mode: Two modules will establish communication automatically when powered. PC hosted mode: Pair the module with bluetooth dongle directly as virtual serial. - Industrial serial port bluetooth, Drop-in replacement for wired serial connections, transparent usage. You can use it simply for a serial port replacement to establish connection between MCU and GPS, PC to your embedded project and etc. Computer and peripheral devices - Default serail port setting : 9600 1 Pairing code : 1234 ## Images ![TOTMC® Arduino Wireless Bluetooth Serial Pass-through Transceiver Module HC-06 RS232 TTL UART Slave + Cable - Image 1](http://ecx.images-amazon.com/images/I/51t8I0rZ9SL.jpg) ![TOTMC® Arduino Wireless Bluetooth Serial Pass-through Transceiver Module HC-06 RS232 TTL UART Slave + Cable - Image 2](http://ecx.images-amazon.com/images/I/41EXUrSFSmL.jpg) ![TOTMC® Arduino Wireless Bluetooth Serial Pass-through Transceiver Module HC-06 RS232 TTL UART Slave + Cable - Image 3](http://ecx.images-amazon.com/images/I/51GaVTA5sKL.jpg) ![TOTMC® Arduino Wireless Bluetooth Serial Pass-through Transceiver Module HC-06 RS232 TTL UART Slave + Cable - Image 4](http://ecx.images-amazon.com/images/I/51KSfa7qr1L.jpg) ![TOTMC® Arduino Wireless Bluetooth Serial Pass-through Transceiver Module HC-06 RS232 TTL UART Slave + Cable - Image 5](http://ecx.images-amazon.com/images/I/41r40Ytt%2B1L.jpg) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pl/products/9084562-totmc-arduino-wireless-bluetooth-serial-pass-through-transceiver-module-hc](https://www.desertcart.pl/products/9084562-totmc-arduino-wireless-bluetooth-serial-pass-through-transceiver-module-hc) --- *Product available on Desertcart Poland* *Store origin: PL* *Last updated: 2026-04-23*
