Wifi espnow type 3 , heap ( memory ) TXQ ( transmit buffer ) error

I receive an error while I am sending the encoded output of amr encoder with espnow to another board. I use: - Lyrat and Lyrat MSC boards. I face the error on both. (Whoever is sending, receives the error after some time). - idf(4.3)-adf(latest). This is the error I face: E (...) wifi:esf_buf t=3 l=...

Is there and advantage of DSP modules of lyrat MSC or lyrat Mini for acoustic echo cancellation?

Hello, ESP-ADF has an algorithm_stream library that enables acoustic echo cancellation (AEC). However, as far as I know, a DSP module is necessary for this operation which is not available on the ESP Lyrat board. Yet, it is still possible to use AEC with Lyrat and I wanted to learn if it has any dif...

How to disable or enable right or left microphone?

For a long time, I have been trying to disable the left microphone and using only the right microphone with i2s_stream (reader). Yet, I have been unsuccessful: I tried to modify many registers with the es8388_write_reg() method. I might not be able to find the appropriate register. Also, it was not ...

AMR-WB causes watchdog error.

I use AMR-WB in my pipeline and when the pipeline starts (with elements run and resume commands) the watchdog timer raises an error repeatedly that it was not reset. (I used separate audio elements and combined them with ringbuffers created manually rather than using the pipeline facility of esp-adf...

UART does not work together with amr codec

Hello. Since I could not receive an answer in the github webpage of esp-adf, I ask this question here also. I have the following pipeline: microphone -> i2s_stream_read -> (input_buffer1) -> amrwb_encoder ->amrwb_decoder ->(input_buffer2) ->i2s_stream_write -> speaker and I use UART1 with TX as GPIO...
