its not working same behavior .

Please verify that you wrote the design capacity successfully. Can you extract a .gg file with bqStudio and an EV2x00 hooked up to your system's I2C bus?

1. I am setting  set_design_capacity[0] = 0x4A , set_design_capacity[1] = 0x27,set_design_capacity[2] = 0x10  (0x2710 -->1000) , after configured data sending using i2c send function  and reading back using i2c read function result is 0x1360.

2. We are not using development kit so not possible to use bqstudio.

Thanks for the reply,

I compiled and run the application code in my board below are the logs.

Console logs:

SUB_CMD_DEVICE_TYPE = 0x0000

FW_VERSION = 0x0000

VOLTAGE = 0004 [mV]

CONTROL_STATUS = 0x0000

source file 'test.gm.fs', size = 1999632428

cannot open data classes source file.

* After reading device type and firmware version invalid not as expected values. could you help me out what is the reason invalid values and checksum(E8) also not as expected value.
