MP280B User’s Guide WARNINGS 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. Caution: 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.
MP280B User’s Guide The requirement for KDB 996369 D03: 1 List of applicable FCC rules FCC Part 15. 247. 2 Summarize the specific operational use conditions None 3 Limited module procedures The module is a single module, so this requirement is not applicable to the product. 4 Trace antenna designs The module uses the permanent PCB antenna, so this requirement is not applicable to the product. 5 RF exposure considerations After evaluation, the SAR requirement is deemed to be satisfied without test.
MP280B User’s Guide 1. General Information The MP280B module works in transparent transmission mode. After the module is powered on, it will be broadcast automatically. The mobile phone that has opened a specific APP will scan and dock it. After successful, it can be monitored by the BLE protocol.
MP280B User’s Guide 2. User Interface The MP280B module uses a 6-pin header for the user interface, or it can be used for patching. pin 1 2 3 4 5 6 function 3V3 GND RXD TXD IO0 IO1 description Power Ground Serial port reception Serial port transmission Reset pin,active low Status pin 2.1 Antenna interface MP280B module uses IPEX carrier, please use IPEX antenna to connect module.
MP280B User’s Guide 3. Transparent protocol The transparent transmission mode of the module means that the universal serial port is connected to the user CPU to establish two-way communication between the user CPU and the mobile device. The module will have different data throughput capabilities for different serial port baud rates and BLE connection intervals, as well as different packet delivery intervals. In order to coordinate the use of low-speed CPU, the default baud rate is 9600bps.
MP280B User’s Guide 4. AT Command The string starting with "TTM" will be parsed and executed as an AT command, and will be returned from the serial port as it is, and then the output execution result will be added, "TTM:OK\r\n\0" or "TTM:ERP\r\n \0" and so on. Serial data packets that do not begin with "TTM" will be considered transparent data. 4.
MP280B User’s Guide "TTM: BPS-?" Will receive from TX: "TTM: BPS-X" Where X="4800", "9600", "19200", "38400", "57600", "115200", (the above data formats are all ASCII). 4.5 Baud rate setting Enter the following string into the serial port RX to set the baud rate: "TTM: BPS-X" Where X="4800", "9600", "19200", "38400", "57600", "115200", (the above data formats are all ASCII). For example, "TTM: BPS-115200" means that the set baud rate is 115200 bps.
MP280B User’s Guide Enter the following string into the serial port RX to set the module's broadcast period, T = X * 100ms: "TTM: ADP-(X)" Where X = "2", "5", "10", "15", "20", "25", "30", "40", "50" (all data formats are ASCII). For example, "TTM: ADP-(2)" indicates that the broadcast period is set to 200 ms. If the setting is successful, it will receive "TTM:OK\r\n\0" confirmation from the TX pin. If the command format is incorrect, it will return: "TTM:ERP\r\n\0" After the module is restarted, the module
MP280B User’s Guide immediately communicate with the new transmit power. If the command format is incorrect, it will return: "TTM:ERP\r\n\0" Note: This parameter is not saved when it is powered down. 4.13 RSSI signal strength output Input the following string to the serial port RX to enable the RSSI signal strength output with an interval of 1 second. "TTM: RSI-ON" Enter the following string into the serial port RX to turn off the RSSI signal strength output.
MP280B User’s Guide 5.1 Default broadcast data After the module is powered on, a default interval of 200ms will be broadcast. The default is 9 bytes of data: { 0x00, 0x00, //custom device type code, default is 00 00, can be set by AT command; 0x00, 0x00, 0x00, 0x00, //four-way PWM current output status (default), or the acquired value of two ADCs; 0x00, //module power supply percentage, 2.
MP280B User’s Guide 6. System reset and recovery There are three ways to reset a module, and a third method can restore system parameters: 1. Reset the module using the AT command; 2. Use the service channel interface to remotely reset the module with APP. 3. Use the hardware RESTORE pin (see the pin definition table).
