I’m running the test.js , a simple script to obtain raw data from the sensor on BBB rev C with debian, it happens to print out the output however, there is this error thrown at the end:

/usr/local/lib/node_modules/mpu9150/node_modules/i2c/lib/i2c.coffee:111
return callback(err, actualBuffer);
^
TypeError: undefined is not a function
at Object._onImmediate (/usr/local/lib/node_modules/mpu9150/node_modules/i2c/lib/i2c.coffee:111:18)
at processImmediate as _immediateCallback

here is the test program:

var mpu9150 = require('mpu9150');

// Instantiate and initialize.
var mpu = new mpu9150();
mpu.initialize();

// Test the connection before using.
if (mpu.testConnection()) {
  console.log(mpu.getMotion9());
}

// Put the MPU9150 back to sleep.
mpu.setSleepEnabled(1);

change every error you have found in i2c.coffee,like readByte,readBytes etc…
