With the AMB82-Mini is there a way to silence all the log info that gets sent to the console?

Hi @GEdmunds ,
May I know what are the log info that you would like to disable? Are you using Arduino SDK or FreeRTOS SDK?

Hi Pammy - the output from the RTSP Streaming sample code. It’s useful when debugging but once things are working right it adds a bit too much chatter. Here is just some of it:

Hi @GEdmunds, we are in the midst of testing and implementing the enable and disable of these logs. I will inform you once it is ready. Thank you

Hi @GEdmunds , As I look into this issue, I’d like to clarify the following:
1. Could I confirm the exact example you’re running that shows this log?
I tested AmebaMultimedia → RTSPStreaming → VideoOnly, but my logs do not contain any [VOE] entries. VOE logs should be disabled by default.
My logs:

Thank you.

Hi - all of that console info comes from running: [Multimedia – RTSP Streaming – Realtek IoT/Wi-Fi MCU Solutions](https://www.amebaiot.com/en/amebapro2-arduino-video-rtsp/)

Hi @GEdmunds,
Thanks for the info, kindly try the newest SDK version or the prerelease version 4.0.9-build20250620, you should not be seeing [VOE] related logs. Meanwhile we will work on other logs. Thank you.

I’d really like to be able to disable all logs that come from drivers and includes other than things I’ve sent in particular. It’s really hard to pick out my own logs on the serial port when there are tens of thousands of “`[ERROR] get_available Accept connection failed`” messages to pick them out of. There are many more logs that I’d like to disable until I need them.
It’d be good to have both a “global disable RealTek logs” and have a method of enabling single logs.

I’ll second this - it would be great if there was a way to silence the messages, and what would really be great is to know what they mean.

An adjacent idea, that might be easier for RealTek to implement: Provide an include or other feature that will allow us to optionally globally channel all messages bound for Serial through a filter function of our own choice.
That would allow us to be very specific about what we let through, develop only-allow, only-reject or maybe even `grep`-like filtering for Serial messages.

Dear all,
You may kindly try out the recent 4.1.0 pre-release version. We have include options to enable and disable some system logs.
Add to preference: [https://github.com/Ameba-AIoT/ameba-arduino-pro2/raw/dev/Arduino\_package/package\_realtek\_amebapro2\_early\_index.json](https://github.com/Ameba-AIoT/ameba-arduino-pro2/raw/dev/Arduino_package/package_realtek_amebapro2_early_index.json)
Note that we are currently still working on the log system to include more options for users to choose.
You may refer to these FAQ to enable or disable the logs.
1. [How can I control debug logs? — Ameba Arduino AIoT Documentation v1.1 documentation](https://ameba-doc-arduino-sdk.readthedocs-hosted.com/en/latest/FAQ/logs_enable_disable_options.html)

With 4.1.0-build20250924 and Arduino IDE Version: 2.3.6 Date: 2025-04-09T11:22:51.016Z
CLI Version: 1.2.0 for MacOS and Logs: Disable All - quite a bit of log information is still heading to the console. This happens on reboot. Do I need to do something differently?

You can refer to [How do I disable the log UART by writing OTP? — Ameba Arduino AIoT Documentation v1.1 documentation](https://ameba-doc-arduino-sdk.readthedocs-hosted.com/en/latest/FAQ/otp_logical_rw.html)
You can turn it off by applying `otp_rom_log_message_disable();` in main. However, OTP has a **limited number of writes**. Avoid repeatedly toggling between enable and disable.
Navigate to main.cpp in cores/ambpro2:
Add the following,
Remove this function after it has been executed. You don’t need to include it every time you upload your code—just run it once. If logs still appear after uploading the code, reopen the Serial Monitor/IDE, then press the reset button on the board.
After you applied `otp_rom_log_message_disable();` and choose Disable all (Soft Mute), you will expect the output. This is the first version of log systems which disable the multimedia’s logs, It is expected that you will still see the WiFi driver related logs.

Hi all,
Kindly try another version of our Arduino SDK pre release version - AmebaPro2@4.1.0-build20250930.
Refer to [Getting started](https://ameba-doc-arduino-sdk.readthedocs-hosted.com/en/latest/ameba_pro2/amb82-mini/Getting_Started/Getting%20Started%20with%20Ameba.html#step-1-selection-ameba-modes) to know more about the options.
