1.1 Little common sense (very important):
TXD: The sender is generally represented as its own sender. Normal communication must be connected to the RXD of another device.
RXD: The receiving end is generally represented as its own receiving end, and normal communication must be connected to the TXD of another device.
In normal communication, the TXD of its own is always connected to the RXD of the device!
Self-receiving: RXD is connected to the TXD of other devices during normal communication. Therefore, if you want to receive the data sent by yourself as the name implies, that is, you receive the data sent by yourself, that is, its own TXD is directly connected to RXD, which is used to test its own transmission and reception. Whether it is normal or not is the fastest and easiest test method. When a problem occurs, the test is first performed to determine whether the product is faulty. Also known as loopback testing.

1.2 Level Logic:
TTL level: Usually the data indicates binary. The specified +5V is equivalent to logic "1". 0V is equivalent to logic "0". It is called TTL signal system and is positive logic.
RS232 level: -12V to -3V, equivalent to logic "0", +3V to +12V logic level, equivalent to logic "1", is negative logic

1.3 Product Features:
1. The core module uses the HC-05 slave module. The lead-out interface includes VCC, GND, TXD, RXD, KEY pin, Bluetooth connection status pin (STATE), unconnected output is low, and the output is high after connection.
2, led indicates the Bluetooth connection status, flashing indicates no Bluetooth connection, slow flashing means entering the AT mode, double flashing indicates that the Bluetooth is connected and the port is opened
3, the bottom plate is set with anti-reverse diode, with 3.3V LDO, the input voltage is 3.6~6V, the current is about 30mA when not paired, about 10mA after pairing, the input voltage is forbidden to exceed 7V!
4, the interface level 3.3V, can be directly connected to a variety of microcontrollers (51, AVR, PIC, ARM, MSP430, etc.), 5V microcontroller can also be directly connected, without MAX232 can not go through MAX232!
5, the effective distance of the open space is 10 meters (power level is CLASS 2), more than 10 meters is also possible, but the connection quality of this distance is not guaranteed.
6. After pairing, when using the full-duplex serial port, you do not need to know any Bluetooth protocol, support 8-bit data bit, 1-bit stop bit, and can set the parity communication format. This is also the most common communication format, and does not support other formats.
7, you can enter the AT command mode by pulling the 34 feet to set parameters and query information
8, small size (3.57cm * 1.52cm), factory patch production, to ensure the quality of the patch. And set of transparent heat-shrinkable tube, dustproof and beautiful, and has a certain anti-static ability.
9, can be switched to the host or slave mode through the AT command, can be connected to the specified device through the AT command
10, support the standard baud rate from 4800bps to 1382400bps

1.4 Product use:
After pairing, it only needs to be used as a serial port with a fixed baud rate. Therefore, as long as the serial port device with "fixed baud rate, 8-bit data bit, no parity" communication format can directly replace the original wired serial port. No need to modify the program. Such as data acquisition, smart cars, serial printers, outdoor dot matrix screen control.
Paired with the computer: suitable for communication between the computer and the device through the Bluetooth serial port, the use method is the same as the serial port
Pairing with mobile phone: suitable for communication between mobile phone and device through Bluetooth serial port, using the same method as serial port
Pairing with Bluetooth host: suitable for two devices to communicate directly through the Bluetooth serial port, such as between the MCU and the MCU, between the wired serial port and the MCU, etc.

Flexible use:
The baud rate is changed because the receiving end and the transmitting end can select the respective baud rate, and can be used as a device for baud rate conversion when the amount of data is small.

2.1 How to connect the Bluetooth module to the computer (effective from slave mode)
   
The following is an example of pairing with a computer with Bluetooth:
First power on the Bluetooth transparent transmission module, at this time led flash, open "my bluetooth position", click "search for devices located within the valid range",
 

The system will search for the Bluetooth device, the default device name is “linvor” (if the name is modified, it is the modified name, such as “jiayuanelectron”), double click or right click to select “Add Bluetooth Device”.

Enter the pairing password (default is "1234"),

Click “Next”. If the password is correct, the computer and the transparent transmission module will establish a connection. If the Bluetooth serial device has not been installed before, the system will automatically install the driver and generate a virtual serial port.

Click on the configuration and select the appropriate COM port.

I can only choose com5 here, this port is the serial port for computer operation after connection. For example, I am com5 here. When this port is opened, the LED of the Bluetooth module will change from flash to double flash. At this time, only the Bluetooth module is needed. It can be used as a serial port with a fixed baud rate of the computer, except that it is wireless.

Purchasing & Delivery

Before you make your purchase, it’s helpful to know the measurements of the area you plan to place the furniture. You should also measure any doorways and hallways through which the furniture will pass to get to its final destination.
Picking up at the store
Shopify Shop requires that all products are properly inspected BEFORE you take it home to insure there are no surprises. Our team is happy to open all packages and will assist in the inspection process. We will then reseal packages for safe transport. We encourage all customers to bring furniture pads or blankets to protect the items during transport as well as rope or tie downs. Shopify Shop will not be responsible for damage that occurs after leaving the store or during transit. It is the purchaser’s responsibility to make sure the correct items are picked up and in good condition.
Delivery
Customers are able to pick the next available delivery day that best fits their schedule. However, to route stops as efficiently as possible, Shopify Shop will provide the time frame. Customers will not be able to choose a time. You will be notified in advance of your scheduled time frame. Please make sure that a responsible adult (18 years or older) will be home at that time.
In preparation for your delivery, please remove existing furniture, pictures, mirrors, accessories, etc. to prevent damages. Also insure that the area where you would like your furniture placed is clear of any old furniture and any other items that may obstruct the passageway of the delivery team. Shopify Shop will deliver, assemble, and set-up your new furniture purchase and remove all packing materials from your home. Our delivery crews are not permitted to move your existing furniture or other household items. Delivery personnel will attempt to deliver the purchased items in a safe and controlled manner but will not attempt to place furniture if they feel it will result in damage to the product or your home. Delivery personnel are unable to remove doors, hoist furniture or carry furniture up more than 3 flights of stairs. An elevator must be available for deliveries to the 4th floor and above.
