Not able to get the BME688 up and running

[Biswajeet]

Hi, 

I am not able to get the BME688 up and running and facing issues and need your help. 

Here are the list of things I have done so far following the "BST-BME688-Integration-Guide-AN008-06.pdf" document. 

1. Took following files from "BSEC_2.0.6.1_Generic_Release_04302021" repo : bme68x.c, bme68x.h, bme68x_defs.h, bsec_datatypes.h, bsec_interface.h, bsec_serialized_configurations_selectivity.c, bsec_serialized_configurations_selectivity.h
2. As our source code is written in C and in the above repo has "bsec.cpp" file present so I had to convert this file from .cpp to .c. (Attached)
3. Execution sequence : 
   1. "bsec_init()" is successfull and able to read the BSEC version information.
   2. "bsec_set_configuration" returns -34 (BSEC_E_CONFIG_VERSIONMISMATCH) insted of 0(BSEC_OK). 
   3. "bsec_update_subscription" returns 0(BSEC_OK). 
   4. "bme68x_init" returns 0(BSEC_OK).
   5. In a infinite loop, executing "read_sensor_and_process_data" or "Bsec::run"(in bsec.cpp). 
      1. Inside "set_bme68x_parallel_mode" is called and "bme68x_set_heatr_conf" functions returns -2 (BSEC_E_DOSTEPS_VALUELIMITS) after which it exits the function and runs in a loop. 

Can you please let me know where is the issue ? 

I have attached the converted c file and logs for your reference. 

Note: The library file was shared here : https://community.bosch-sensortec.com/t5/MEMS-sensors-forum/BME688-library-linking-fails-in-STM32MP1...

Hi BSTRobin, 

Any update on this ?

[BSTRobin]

It is on going to release BSEC2 C code. If the software is ready, we will let your know.

Hi,

Any further update on this request? We are stuck with the BME688 sensor issues and unable to make the necessary deliverables which is hindering our time to market. Can you please treat this on a priority basis. If you cannot help, please share the escalation matrix.

Hi skodavalla,

Sorry for the delay reply. I have submitted your request, but BSEC C code may be released in Q4 2022.
If you design a project with BME688 in your project with urgent time, could you provide your company email? Then we could directly communicate with you by email.

Any further update on this? Timeline? We are in Q4'22 - Right?
