CC2640: configuring bq25892 battery charger with cc2640 via i2c

Hi,

I am trying to configure bq25892 battery charger with cc2640 i2c interface. But I am facing one issue when ever i update values and try to to read them for the first time I am getting correct values which i updated but next time i try to read the same value it reads default value.

static uint8_t REG04[2] = {0x04,0x2C}; //0x04 is REG04 of battery charger and 0x2C is fast charge current limit settings

static void Battery_charger_init()

{

    i2c_status = bspI2cOpen();

 if (i2c_status == TRUE)
{
      while(bspI2cSelect(interface_0, slaveaddr_charger) == 0)  //slaveaddr_charge= 0x6B , interface_0 = BSP_I2C_INTERFACE_0
      {
        Task_sleep(MS_2_TICK); // (((100) * 1000) / Clock_tickPeriod)
      }

      {
            if (bspI2cWrite(REG04,2) == true)
            {
                  UART_write(SbpUartHandle, "REG0A writen \n\r", 15);
              /* Success */

            }

         }

}

      bspI2cDeselect();

   bspI2cClose();

}

 

in simple bleperipheral

//    battery event after every 10 sec event occurs
    if (events & BAT_TIMER_EVT)
    {
      events &= ~BAT_TIMER_EVT;


      i2c_status = bspI2cOpen();

   if (i2c_status == TRUE)
          {
          UART_write(SbpUartHandle, "i2c true \n\r", 11);
       while(bspI2cSelect(interface_0, slaveaddr_charger) == true)     //interface_0 = BSP_I2C_INTERFACE_0,slaveaddr_charger = 6B
       {
        Task_sleep(MS_2_TICK);
       }

       {
           if (bspI2cWriteRead(&REG0000, 1, &reg00, 1) == true)
            {
              /* Success */
                  UART_write(SbpUartHandle, "\n\r reg00 \n\r", 7);
                  UART_write(SbpUartHandle, &reg00, 1);

            }
}

      bspI2cDeselect();

bspI2cClose();

}
