Check the PCB traces that are related to the CAN communication.

You can modify the code like this: #include <BLEDevice.h> #include <BLEServer.h> #include <BLEUtils.h> #include <BLE2902.h> #include <Adafruit_INA260.h> #define uS_TO_S_FACTOR 1000000ULL // Conversion factor for micro seconds to seconds #define TIME_TO_SLEEP 60 // Time ESP32 will go to sleep (in sec...

"waiting for download," is likely related to a mismatch in the COM port settings or a problem with the board configuration. In your output, you flash the device on COM3 but the monitor attempts to connect to COM4.

For Matter over Wi-Fi, the communication between the controller (chip-tool) and the devices indeed goes through the local Wi-Fi router, utilizing the assigned local IP addresses for routing within the local network.

You can try this. Run these commands on the initiator device: > bdb -r zr > bdb -t d > bdb -c 11 > tlk -k 00112233445566778899aabbccddeeff > bdb -s > bdb -i init > bdb -a init > bdb -a initiator Run these commands on the first target device: > bdb -r zr > bdb -t d > bdb -c 11 > bdb -m 10 > tlk -t he...

Here is a github thread regarding the run command failure.

muting the microphone while audio is being played through the speaker can be done by programming.

Thanks. The second pic looks so beautiful.

Ensure that your code is optimized for performance to achieve the highest clock frequency possible. This includes minimizing interrupt latency, reducing unnecessary computations, and optimizing loop structures.

Implement an anti-aliasing filter on the PWM output signal to remove high-frequency components before it reaches the amplifier. This can help in reducing aliasing effects in the output signal.
