Grove Pi + Raspberry Pi Multichannel Gas Sensor

I am using the Raspberry Pi 3 B model with Grove Pi + (1.2.2) firmware and Raspbian for Robots Image. I plug in a multi-channel gas sensor in the I2C-1 port and I try to execute the code available in Dexter's Github , I get the following problems:

> Traceback (most recent call last): File "/home/pi/Desktop/GrovePi/Software/Python/grove_i2c_multichannel_gas_sensor/multichannel_gas_sensor.py", > line 85, in m= MutichannelGasSensor() File > "/home/pi/Desktop/GrovePi/Software/Python/grove_i2c_multichannel_gas_sensor/multichannel_gas_sensor.py", > line 39, in init if self.readR0() >= 0: File > "/home/pi/Desktop/GrovePi/Software/Python/grove_i2c_multichannel_gas_sensor/multichannel_gas_sensor.py", > line 45, in readR0 rtnData = self.readData(0x11) File > "/home/pi/Desktop/GrovePi/Software/Python/grove_i2c_multichannel_gas_sensor/multichannel_gas_sensor.py", > line 70, in readData buffer=bus.read_i2c_block_data(self.address, cmd, > 4)IOError: [Errno 110] Connection timed out

When I launched the old GrovePi + firmware, this error did not appear, but it did not work, nothing is displayed on the screen.

Checking the code line by line, I understand that on line 71 there is a print (data) after the buffer = bus.read_i2c_block_data (self.address, cmd, 4), but the variable "data" is not defined in the code, Something is strange in this code .

Can someone help me with this grove sensor? Can someone tell me?

There are several problems that we encountered while porting the code for the sensor. It was at the same I2C address as GrovePi, and the data returned from it was not consistent. Therefore, Sensor is not working right now with GrovePi, and work with the code is still ongoing, it may take some time to do this.
