This series of module uses TI CC254x chip design, following BLE4.0 Bluetooth specification. The module uses industry standard, increasing the various protection circuit, anti crash circuit design. It uses the standard RS232 physical interface. The inside has embedded within a special Jinou firmware program, so that users can set the parameters themselves, such as baud rate, device name etc. The way of plugging then using can realize the wireless data transmission between devices directly. Bluetooth serial adapter has the distinction of principal and subordinate, and one principal matches one subordinate. The principal and subordinate equipment can establish connection automatically, and identify and memorize each other when the hardware circuit of Bluetooth serial adapter connects correctly. Then user’s equipment can use the Bluetooth serial adapter the same as serial wires.
Besides one to one use, the Bluetooth serial adapter can use independently. For example, the user’s equipment connects a RS232 embedded module of the subordinate equipment. Then, the other Bluetooth device such as Bluetooth pad (win8+ ), cellphone (Android 4.3+, ios 7.0+) etc. can search this device, and discover the provided service. According to the service, it can establish links and communication with the adapter. This module can still be used the same as the serial wires for the communications of users' equipment.
