Hello I'm creating a set of trackers form Wemos D1 Mini and MPU6050 and IDK why I have info like this:

[INFO ] [SerialCommands] SlimeVR Tracker, board: 6, hardware: 1, build: 16, firmware: 0.3.3, address: 192.168.100.145, mac: A0:20:A6:23:15:21, status: 0, wifi state: 3
[INFO ] [SerialCommands] Sensor[0]: MPU6050 (0.000 0.000 0.000 0.000) is working: true, had data: false

IDK why tracker don't receive any data.

I test it with i2c_scanner and MPU was found. GY-521 examples all works and return the data.

The defines.h file content:

#define IMU IMU_MPU6050
#define SECOND_IMU IMU
#define BOARD BOARD_WEMOSD1MINI
#define IMU_ROTATION DEG_180
#define SECOND_IMU_ROTATION DEG_90

#define MAX_IMU_COUNT 1

#ifndef IMU_DESC_LIST
#define IMU_DESC_LIST \
    IMU_DESC_ENTRY(IMU,        PRIMARY_IMU_ADDRESS_ONE,   IMU_ROTATION,        PIN_IMU_SCL, PIN_IMU_SDA, PIN_IMU_INT  ) 

#endif

// Battery monitoring options (comment to disable):
// BAT_EXTERNAL for ADC pin, BAT_INTERNAL for internal - can detect only low battery, BAT_MCP3021 for external ADC
#define BATTERY_MONITOR BAT_EXTERNAL
#define BATTERY_SHIELD_RESISTANCE 180 //130k BatteryShield, 180k SlimeVR or fill in external resistor value in kOhm

#define PIN_IMU_SDA 0
#define PIN_IMU_SCL 2
#define PIN_IMU_INT 14
#define PIN_IMU_INT_2 12
#define PIN_BATTERY_LEVEL A0

Is like that because with D's trackes don't achieve even second state of configuration so i use GPIOs.
