    Yes, but you have to solder a bluetooth board to it. Perfectly possible, but will drain the battery even faster.

    Look for GY-87, or HMC5883L, BMP085 and MPU6050 on Ebay and Aliexpress.https://www.aliexpress.com/

    Sorry man, but I dont pan to make updates to the project.

    No. Probably because your display is different from mine. Each display has a different configuration. Uploading the same code will generally never work, because probably the parts are slightly different one from the other. Test the code part by part.
