About RPN93

Hi BSTRobin, Im using my own PCB design with BME688 component. BME688 works with I2C, and Im using 'Contiki' operative system for this. This implementation worked with BME68x-API. For BSEC, I have followed the official examples on github. In the main() function I've initialice 'bsec_init()' and 'bsec_update_subscription()'. The outputs that I want are this: requested_virtual_sensors[0].sensor_id = BSEC_OUTPUT_IAQ; requested_virtual_sensors[0].sample_rate = BSEC_SAMPLE_RATE_HIGH_PERFORMANCE; requested_virtual_sensors[1].sensor_id = BSEC_OUTPUT_CO2_EQUIVALENT; requested_virtual_sensors[1].sample_rate = BSEC_SAMPLE_RATE_HIGH_PERFORMANCE; requested_virtual_sensors[2].sensor_id = BSEC_OUTPUT_RAW_TEMPERATURE; requested_virtual_sensors[2].sample_rate = BSEC_SAMPLE_RATE_HIGH_PERFORMANCE; requested_virtual_sensors[3].sensor_id = BSEC_OUTPUT_RAW_PRESSURE; requested_virtual_sensors[3].sample_rate = BSEC_SAMPLE_RATE_HIGH_PERFORMANCE; requested_virtual_sensors[4].sensor_id = BSEC_OUTPUT_RAW_HUMIDITY; requested_virtual_sensors[4].sample_rate = BSEC_SAMPLE_RATE_HIGH_PERFORMANCE; Then , in the loop, I do next: For 'bsec_do_steps()' I used the next inputs: inputs[0].sensor_id = BSEC_INPUT_PRESSURE; inputs[0].signal = dataBME.pressure; inputs[0].time_stamp = time_stamp; inputs[1].sensor_id = BSEC_INPUT_HUMIDITY; inputs[1].signal = dataBME.humidity; inputs[1].time_stamp = time_stamp; inputs[2].sensor_id = BSEC_INPUT_TEMPERATURE; inputs[2].signal = dataBME.temperature; inputs[2].time_stamp = time_stamp; inputs[3].sensor_id = BSEC_INPUT_GASRESISTOR; inputs[3].signal = dataBME.gas_resistance; inputs[3].time_stamp = time_stamp; inputs[4].sensor_id = BSEC_INPUT_HEATSOURCE; inputs[4].signal = 0.0f; inputs[4].time_stamp = time_stamp; So what could be the problem for IAQ=0 AND co2 =0?? Accuracy for all the values return 0. Thanks. ... View more

Hi Minhwan, first of all, thanks for answering. I have done what you said and know the result of bsec_sensor_control() is ok, but I have seen that the next_call time is 5minutes, so I have to wait this time each loop. Is there any way to decrease nex_call? Thanks. ... View more

Hi BSTRobin, thanks for answering. I've already seen this code with the others one, but this is made for arduino. Is there any example in C where I can compare? Because in the code you said, to initialice they are using funcions defined in 'bsec.c' file, which is supposed to not be included in my project if I have the BME68x-API. Thanks ... View more
