    Hi Zeliha,

    I'm not sure why the communication would stop working if it was working before, but here are a few things you can try:

    • Make sure to follow all of the steps in the EVM User Guide Quick Start section like:
      • The shunts from the headers connecting the AFE to the gauge should be removed. These are located in the upper left-hand corner of the EVM.
      • 4-pin cable is connected between EV2400 and EVM I2C connector
      • USB cable connected from PC to EV2400. Three green LEDs should be on for the EV2400
      • Ensure power supply is connected to EVM BATT terminals
      • Press and release the BOOT switch on the EVM to wake up the BQ76930
    • If the EV2400 is suspected, you can re-program the EV2400 firmware. The latest firmware and the instruction for installing are located in the EV2400 product folder. 

    I hope this helps you to find the issue.

    Best regards,

    Matt

    Thank you Matt Sunna ;
    I tried but it can not be help. Is it possible that the device shifted to  ship mode ; if it is so what can ı do then?

    Sincerely..
