Compatible with Android apps, it features an STM8S MCU, onboard indicators, and easy configuration, making it ideal for IoT and smart automation projects.

## Description

Product Parameters Onboard STM8S high-performance MCU serial port slave module Bluetooth relay control APP is provided Onboard Bluetooth status indicator and relay indicator The UART debugging interface and STM8 SWIM program download interface are reserved Control distance: 10m (open environment) Operating voltage: DC 12V Maximum DC control voltage: DC 30V Maximum AC control voltage: AC 250V Size: 20mm*62mm Basic functions and instructions IN+: positive terminal of the DC 12V power supply IN-: DC 12V power source COM: public terminal NO: Normally open interface of the relay. The relay is suspended before closing and shorted with COM after closing NC: normally closed interface of relay, short connected with COM before relay closing, suspended after closing Basic operation instructions: After the connection is correctly connected, install the "Bluetooth Smart Control" APP on the Android phone, search for the Bluetooth device and connect it. The pairing password is 1234, long press the gray box in the interface to add the serial port instruction, and input the name and content of the instruction (open the relay when the instruction content is A00101A2; Turn off the relay when the instruction content is A00100A1) and select to send in hexadecimal form, then click the corresponding box to control the switch of the relay, or download other Bluetooth apps in the APP store to control by sending instructions. Tip: Currently, the module only supports Android system, not IOS.

Review: After finally finding an app that would work for it (Relay Widget Bluetooth &Wifi on playstore then use command profile 2 in the app) it works good, but anytime I want to use it I have to go to Bluetooth and forget it and reconnect. I'm not happy with this item due to Bluetooth connectivity. If it gets better I'll update, but I doubt it!
Review: It’s great.

Even with instructions provided by another person who purchased this and figured out how to make this work, no luck for me. Why should we have to deal with all this anyway ? Just provide a working app that simplifies usage like everyone else.
