Description：
Features:
JDY-31 Bluetooth-compatible is based on Bluetooth-compatible 3.0 SPP design, which can support Windows, Linux, for android data transmission, working frequency 2.4GHZ, modulation mode GFSK, maximum transmission power 8db, maximum transmission distance 30 meters, support users to modify device name through AT command The baud rate and other instructions are convenient and quick to use. This Bluetooth-compatible module can only be used as a Bluetooth-compatible slave.
JDY-31 is a classic Bluetooth-compatible protocol that can communicate with Bluetooth-compatible-enabled computers (desktops, notebooks) and mobile phones (for android).

JDY-31 support patch and solder pin header
Needle pin application: The pin header specification is standard 2.54 pitch pin header, just need to weld 5 pin holes on the module.
SMD application: Generally, only four pins of VCC, GND, RXD and TXD need to be connected. If you need to disconnect actively in the connection state, send AT+DISC in the connection state.
