10 DOF Mems IMU Sensor Can't Initialize With Beetle BLE

Product SKU: SEN0140
IDE: Arduino IDE v 1.8.12
Libraries:
- FreeSixIMU https://github.com/DFRobot/FreeSixIMU
- HMC5883 https://github.com/DFRobot/DFRobot_QMC5883.git
- BMP280 https://github.com/DFRobot/DFRobot_BMP280.git

Jumping straight into the problem, I am attempting to get any sort of output from the 10 DOF Mems IMU Sensor and have been following the tutorial on the docs (https://wiki.dfrobot.com/10_DOF_Mems_IM ... U__SEN0140).

I currently have the board wired up like this: https://imgur.com/a/lxMd4zP

I am using this code provided in the docs to run a simple test:
Code: Select all
#include <FreeSixIMU.h> #include <FIMU_ADXL345.h> #include <FIMU_ITG3200.h> #include <Wire.h> float angles[3]; // yaw pitch roll // Set the FreeSixIMU object FreeSixIMU sixDOF = FreeSixIMU(); void setup() { Serial.begin(9600); Wire.begin(); Serial.println("In setup"); Serial.println("About to delay"); delay(5); Serial.println("Before sixDOF.init"); sixDOF.init(); //begin the IMU Serial.println("Just began the IMU"); delay(5); } void loop() { Serial.println("Before get angles"); sixDOF.getEuler(angles); Serial.println("After get angles"); Serial.println(angles[0]); Serial.println(angles[0]); Serial.println(" | "); Serial.println(angles[1]); Serial.println(" | "); Serial.println(angles[2]); delay(100); }

Using a few Serial.println statements, I noticed it gets hung up on line 20 (sixDOF.init(); //begin the IMU).
The Bluno Beetle was able to work with a test that simply printed hello world to the serial monitor in a loop, so I believe the problem is with the sensor. Does anyone have any way to fix this error or know of any other ways to debug the device?
