Yes, the code is C++ and wrote for Raspberry Pi 4. The goal is just save "state" from the BME688 before device is powered off and load "state" back to BME688 just before start BME688 function. And there is no AI feature is included.

Hello everyone, I am just looking for your feedback for snipping of the C++ coding. Because bsec_get_state() and bsec_set_srare() with fread() and fwrite() example is absent from the BME68X Sensor API at the github site. Also, I am not very talented with C++, just a novice. The program is compiled and running fine. But I am not sure if it is ACTUALLY working or not. I don’t have a debug tool to see if it is behaving appropriately. The coding is expecting to run on Raspberry Pi 4 it is using bsec_2-0-6-1_generic_release_04302021.. Here are the snipped coding with bsec gets_state() for loading state from file and is set to BSEC; Usual error check logics are removed to simplify. >>> bsec_state = fopen("/tmp/bme68x.state", "rb"); unit8_t = result; result = fread(serialized_state, sizeof(unsigned char), BSEC_MAX_STATE_BLOB_SIZE, bsec_state); bsec_result = bsec_set_state(serialized_state, n_serialized_state, work_buffer_state, n_work_buffer_state); <<< And here are tyhe snipped coding with bsec_set_state() and save state into the file. >>> bsec_state = fopen("/tmp/bme68x.state", "wb"); bsec_state = bsec_get_state(0, serialized_state, n_serialized_state, work_buffer_state, n_work_buffer_state, &n_serialized_state); result = fwrite(serialized_state, sizeof(serialized_state), 1, bsec_state) <<<
