Instructions for use
| Pin | Function Description |
| GND | Negative pole of power supply |
| NC | Short circuit GND, can upgrade CH582 firmware, generally suspended |
| XCL | External magnetometer, program needs to be modified by oneself; Otherwise, it will remain suspended |

| RXD | Data receiving end |
| TXD | Data sender |
| 5V | Positive pole of power supply, compatible with 3.3V~5V |
se CH340 serial port to connect the board, TX RX crossover. The blue light on the board will remain on (initialization) and then start flashing (normal operation). Open the serial assistant to see the data transmission.
Protocol analysis
The output format is JustFloat format, where every 4 bytes represents a Float data and ends with 00 00 80 7F
JustFloat | VOFA Plus upper computer VOFA Plus upper computer | VOFA Plus upper computer
You can view data using the VOFA upper computer, and drag the Cube control to view attitude changes online
A total of 10 types of data are output, all from the internal registers of MPU6050, and the attitude angle is calculated by DMP
In order, they are:
1.gryoX
2.gryoY
3.gryoZ
4.accX
5.accY
6.accZ
7.Roll
8.Pitch
9.Yaw
10.temperature
Bluetooth transmission

Install Bluetooth analysis tool on Android phone and connect the Bluetooth of MPU6050uBLE in the tool
Find the last service and click the arrow to retrieve the data
Bluetooth serial port module BLE5.2 ECB02C BLE serial port transparent transmission secondary development - Taobao. com
By using this Bluetooth to serial port tool, data can be obtained directly on the computer
Just send the command as shown in the picture. The serial tool has already set the command in the compressed file
If the MPU6050uBLE serial number is scanned as 1, then AT+CONNECT=1 sends
If the MPU6050uBLE serial number is scanned as 2, then AT+CONNECT=2 will be sent
You need to modify the sequence number of the sending instruction by yourself
If unable to connect, power off and restart both MPU6050 and Bluetooth serial port before reconnecting
