"Could not allocate arena" after adding Bluetooth functions to voice recognition code

73 Views Asked by At

I am trying to make a Bluetooth speaker controlled by voice commands. I have successfully written code to connect to the speaker via Bluetooth. Then I have successfully trained a neural network and got the speaker to recognize my commands (Speaker has a microphone). I followed this tutorial and code: https://github.com/atomic14/voice-controlled-robot/tree/main/firmware. However, when I try to combine the two codes together, I get a "could not allocate arena" error and the code doesn't run properly. All I did was add "#include <btAudio.h>", "btAudio audio = btAudio("ESP_Speaker");", and "audio.begin();" to the main file of the voice recognition code. I have attached code for the main file. All of the other files are pretty much unchanged. In addition, I've attached a picture of the output after the program uploads: Code output. Does anyone have an idea on how I should approach fixing this error? Thank you.
