Characteristics values specification

[argalasjr]

Dear Nordic Semiconductor

I am using device:

NRF51802 bluetooth 4.0

Product Introduction:

Features:

1.Adopt NRF51802 bluetooth 4.0 BLE SOC 

2.ARM CORTEX-M0  

3.Adopt MPU6050 chip 

4.Adopt BMP280 temperature atmospheric pressure sensor chip 

5.Ambient light proximity sensor chip AP3216

6.With power switch 

I struggle with using values that I get from notify services of my device.

This is the output I am getting from all notify services:

• 1: bmpData 
  • service: "6a800001-b5a3-f393-e0a9-e50e24dcca9e"
  • characteristic: "6a80b280-b5a3-f393-e0a9-e50e24dcca9e"
  • RESULT FROM NOTIFY SERVICE:
  • Uint8Array(8) [0, 1, 135, 124, 0, 0, 0, 23]
• 2: mpuData 
  • service: "6a800001-b5a3-f393-e0a9-e50e24dcca9e"
  • characteristic: "6a806050-b5a3-f393-e0a9-e50e24dcca9e"
  • RESULT FROM NOTIFY SERVICE:
  • [[Int8Array]]: Int8Array(12) [7, 46, 2, 120, -66, 88, -1, 116, 0, 44, 0, 19]
  • [[Uint8Array]]: Uint8Array(12) [7, 46, 2, 120, 190, 88, 255, 116, 0, 44, 0, 19]
  • [[Int16Array]]: Int16Array(6) [11783, 30722, 22718, 29951, 11264, 4864]
  • [[Int32Array]]: Int32Array(3) [2013408775, 1962891454, 318778368]
• 3:apData - tu mi pride najviac pravdepodobna vzdialenost
  • service: "6a800001-b5a3-f393-e0a9-e50e24dcca9e"
  • characteristic: "6a803216-b5a3-f393-e0a9-e50e24dcca9e"
  • RESULT FROM NOTIFY SERVICE
  • Uint8Array(2) [0, 0]

I need to see documentations for this values in Arrays and how  to correctly use them for getting :

Acceleration values, Gyro Values and Temperature.

Thank you for answer and your time

Best Regards

Argalas

Theese values come from my own code. 
Using Ionic 5 Application with Cordova-plugin-ble-central for subscription to raw data (Notify services on device)
Cant find explanation of values in documentation for MPU data

Hi,

I see. I cannot say by looking at the strings of data that this is. I suggest you check the MPU-6050 datasheet to understand how to use it. If you need more information it is probably better to ask MPU-6050 specific questions on the InvenSense forum. In that case, you should also show the code you use to get the values you print here, as without seeing your code it is difficult to know where this comes from.
