FCC Warning
This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation. NOTE 1: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures: - Reorient or relocate the receiving antenna. - Increase the separation between the equipment and receiver. -Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. -Consult the dealer or an experienced radio/TV technician for help. NOTE 2: Any changes or modifications to this unit not expressly approved by the party responsible for compliance could void the user's authority to operate the equipment.

1 Features
This module is a BLE transparent transmission module designed based on the Bluetooth Low Energy standard published by Bluetooth SIG. This module is controlled through the serial port and also supports wireless control through the host side. Users do not need to pay attention to complex Bluetooth protocol application software, and can develop standard low-power Bluetooth products in a short period of time. After the connection is established through serial control, two-way data transmission can be realized between the BLE host and the slave.
1.1 Functional Overview
1. Support fully transparent transmission 2. Support serial port command to modify and get module settings 3. Power consumption and performance can be independently weighed and selected 4. The fastest one-way communication rate can exceed 3kBytes/s 5. Support serial large data packets of up to 200 bytes, and the module can buffer and sub-package
independently 6. Serial port configuration {or read) parameters such as baud rate, device name, broadcast interval, etc. 7. Abundant 1/0 control and status indication functions, simpler and real-time control module and obtain
module status 8. Simpler software and hardware design requirements

5 Module Transparent Transmission Protocol
5.1 AT command configuration
<AT+> command refers to the command set passed by user through UART and module input command in command mode. The usage format of AT+ command will be explained in detail later. After power-on and startup, you can set the default UART of the module through UART. The port parameters are z baud rate 115200, no parity, 8 data bits, and 1 stop bit.
5.2 AT command overview
<AT+ >commands can be input directly through serial debugging programs such as CRT, AT+ commands use command lines based on ASCII codes, and the format of the commands is as follows. 1. Format description
< >: Indicates the part that must be included [ ]: Optional part 2.Command Message AT+<CMD[p][para-1,para-2,para-3,para-4CR><LF> AT+: Command message prefix: [op]: Command operator, specify parameter setting or query: "=": Indicates parameter setting "?": means query [para-n]: Input for parameter setting, such as query does not need: <CR>: end character, carriage return, ASCII code OXOD; <LF>: end character, line feed, ASCII code OXOA; 3. Response message <CR><LF>+<RSP>[op] [para-1,para-2,para-3,para-4 ]<CR><LF> +: Response message prefix: RSP: Response string, including 2 "OK": means success "ERR": Indicates failure

[para-n]: Return parameters when querying or error code when error occurs
<CR>: ASCII code 0x0D;
<LF>: ASCII code 0x0A;
