How to get classification.result[ix].value

[alvinzulham]

I want to use the classification result as conditional (if(){}) parameter but not doing according to what is in the condition. and also I tried to Serial.print the classification.result[ix].value but it get error said no matching function for call to ‘arduino::UART::println(ei_impulse_result_classification_t&)’

I think I should create new function similar to print function in edge (ei_printf) to return the value, but I don’t know how to do it, or there is other solution? thanks in advance

Hello @alvinzulham,

If you want to grab the results classification you can do something similar to this which lights on a LED according to the classification results. It’ll give you an idea of how you can do something with the inference results:

The voice model is trained on the Edge Ipulse to control the lighting and turning off of LED

Hi @Joker, I used the nano_ble33_sense_microphone_continous.ino example. You can add something similar to this in the loop function : void loop() { bool m = microphone_inference_record(); if (!m) { ei_printf("ERR: Failed to record audio...\n"); return; } signal_t signal; signal.total_length = EI_CLASSIFIER_SLICE_SIZE; signal.get_data = &microphone_audio_signal_get_data; ei_impulse_result_t result = {0}; EI_IMPULSE_ERROR r = run_classifier_cont…

Do you have example for nano_ble33_sense_microphone.ino ? because it have error when apply the example code
