BME680 gas_meas_index_0 position in register set

[klaus_b]

Hello,

it seems there is a mismatch between the datasheet and the driver source code. gas_meas_index_0 in the datasheet is positioned in the status register eas_status_0 at address 0x1d. Address 0x1e is not used obviously. In the source code (function read_field_data) meas_index is read from buff[1], which should be BME6080_FIELD0_ADDR+1, i.e. 0x1e.

Which one is correct?

Regards

Actually 0x1E is reserved register which is not listed in datasheet but used by the API.   And it has definately important meaning while calculate the gas register.  

So both are correct.  😀
