DC 12V 8 Channel Relay Module bluetooth Wireless Control Switch

APP download(click) Features: Effective transmission distance 10M. Mini51 series is used as Cortex-M0 32-bit microcontroller series with high performance, low power consumption and fast processing speed. bluetooth remote control, safe, convenient, fast, simple, low power consumption. Specification: Power: 12V It needs external relay to play the role of switch Factory bluetooth device name is QS-8RELAY (8 way is QS-8RELAY, by analogy) the best to have a unique number. Password: 123456 Modify bluetooth device name fD 02 EF + Total length 1 byte (all subsequent bytes) + length + device name n bytes (up to 10 bytes) + length + paired password (PIN up to 6 bytes) + 5D (e.g. modifying the device name: QS-RELAY pairing code: 1234 is sent: FD 02 EF 0F 08 51 53 2D 52 45 4C 41 59 04 31 32 33 34 5D) Modified success: DF FF 0000 5D modified failed, no response: DF 000000 5D Firstly, APP sends the name of the device to be modified, disconnects the bluetooth connection, resets the bluetooth module after the hardware receives, delays several seconds to reconfigure the bluetooth device. Package Included: 1 x 8 Channel Relay Module
