Overview

Jinou serial port adapter is an intelligent wireless data transmission product developed by our company. It supports the latest Bluetooth 5.0 protocol specification, and the overall performance is more optimized.
Determined by the nature of low power consumption, BLE is mainly applied in the transmission of a small amount of data, different from BR/EDR (traditional Bluetooth) characterized by voice transmission, or Bluetooth 3.0 characterized by high-speed data transmission. In order to ensure its low power consumption, BLE simplifies handshake protocol and reduces wake-up time, which is quite suitable for transmission of short-time and small data.
In order to ensure low power consumption, low power consumption simplifies handshake protocol and reduces wake-up time. In this type of data transmission, the power consumption of the low-power Bluetooth is only one- tenth of that of the traditional Bluetooth, while in the long – time and large – data transmission, the handshake protocol and the wake-up time account for a lower proportion in the data amount of the entire task and the total duration, and the advantage of low power consumption is greatly reduced.
JINOU serial adapter adopts the low-power Bluetooth scheme of TI company and supports the BLE mode. Can be used in applications sensitive to power consumption, such as consumer health care, mobile accessories, sports, and health applications.
The device implements the function of data transmission through the RS232 interface and remote low-power Bluetooth, and the device contains two different working states of data mode and configuration mode.
Communication mode: The device can be connected to the remote BLE or searched connected by the remote BLE. After the connection is finished, it can transmit data with the remote BLE bidirectional data.
Configuration mode: the user can configure parameters such as device name, baud rate, etc. In this state, the device cannot be found connected.

Note1: Here refer to that data – to – transmission rate between the two adapters, which relate to connection parameters, such as different phone and adapter data, the rate may be different. If need it up to maximum transmission rate, please set the baud rate to 230400.
Note1: The data transmission power consumption is the power consumption data continuously transmitted at a 9600 baud rate within the effective range of 10m.

Description of Indicator Light and button

The BLE serial adapter has three LED lights to indicate the operating status of the device and a mode switch button.

①RS232 interface

② Status indicator (green)
③ Operation indicator (red)
④ Mode switch button (CM D button)
⑤ Power indicator (red)
⑥ Power interface

RS232 port:

The BLE serial adapter provides a standard RS – 232 interfaces and supports multiple serial port modes.
The equipment RS – 232 DB9 pins is capable of power supply and can be used for user-developed equipment. 1. pin 9 is VCC, pin 5 is GND, 6 ~ 9VDC, 100mA rated current.

Power Interface:

**** 6 VDC, 200mA rated current; internal positive and external negative.
The positive and negative poles of the power supply cannot be reversed or the products will be burnt out.

Indicator:

In the parameter setting state, press the CMD button again, and the device exits the parameter setting status and enters the network working state.

Indicator:

The adapter has three indicator lights, the power indicator (red), the main/slave mode indicator (red), and the connection indicator (green).
When the BLE adapter is powered on, the power indicator (red light) will always be on.
If the master/slave mode indicator (red light) flashes every few seconds, the adapter is working properly. The time interval between the flashing lights can be used to determine whether the device is the master device or the slave device. If it flashes once every 2 seconds, it is the slave device. If it flashes once every 5seconds, it is the main device.
If the connection indicator (green light) is off, it means that a connection has been established with other Bluetooth devices. If it flashes once every 1 second, it means no connection has been established.
When the BLE adapter is working in parameter setting mode, the master/slave mode indicator light and connection status indicator light are extinguished.

Mode switch button:

After power on, BLE adapter is in data mode, master/slave mode indicator light and connection status indicator light flash, press the switch button of mode, the device enters the parameter setting state, master/slave mode indicator light and connection status indicator light extinguished, and output “+OPEN” from the serial port. In the parameter setting state, the serial port parameter remains 9600bps, 8-n-1. The device stops the network part and turns off the wireless signal. At this time, only the device parameters can be set.

Operation Instruction

The default setting of this device is 9600bps baud rate, 8-n-1 communication mode, no flow control, the slave device, and the matching code is 000000.
If need to change parameters, the user should press the mode switch button to enable the adapter to enter the parameter setting state. The two previously blinking indicator lights are off and relevant parameters are set through the “AT command”, such as the parameters of master/slave device, baud rate, remote address, etc.
If 2pcs adapters need to communicate, the user must set one as a master device and another as salve device. Users can tell roles from the operation indicator light.
Note: the parameters are stored in FLASH, so the values of the parameters will remain the same even after the power is cut, and will not be lost.
After parameter modification, short press the mode switch button again to enable the adapter to enter data mode.
The adapter should be in data mode when powered on. For the master device, if the address has been memorized, the master device is directly connected to the memory device, which can be cleared by the “AT+CLEARADDR” instruction.
For slave devices, wait to be queried and connected by other devices.
If the two adapters are connected successfully, the connection status indicator (green light) is off and the master/slave mode indicator (red light) remains to flash. At this point,  the user device is just like a serial port connection, sending and receiving data directly.
Once the device is connected, our serial port adapter will not be automatically disconnected unless the signal is poor or the other party’s Bluetooth is actively disconnected, and the connection will remain.
Note: the following frequently asked questions section gives an important supplement to the use of the equipment and solutions to the problems that customers usually encounter. Please read this section carefully before using it.

Description of the authentication mode

The BLE serial port adapter only stores the matching information of one master device at most. Therefore, when the authentication function is enabled and matched with the master device (such as IOS, Android phone, or tablet), the matching connection with the new master device will first clear the previous host matching information. Therefore, a rematch is required when the previous master device connects to the BLE serial adapter again.
However, when some master devices (such as IOS Ipad) are connected again because the matching information of the BLE serial port adapter is saved before, the master device does not re-initiate the match after receiving the BLE serial port adapter re-matching request, which will result in authentication failure and thus disconnection. In the case of disconnection, first, delete the BLE serial port adapter matching information in the Bluetooth option of the master device’s system settings, and reconnect it again.

Parameter configuration

In parameters setting mode, the default parameter is 9600bps, 8-N–1, no CTS RTS flow control. The following < CR >, < LF > in tables represent ASCII code of the “Enter” and “line feed”.
Every AT command send to the module needs to end up with the two codes. Otherwise, the AT commands can not be recognized. As for < >, it is used for convenient reading.  In fact there is no < > in command.

Testing Command

Parameter Setting Mode Indicate

status 0: no remote address is configured
