Hi
In our code ,we enable BLE and WIFI(lwip tcp).
The codes works with esp-idf Release 3.3.4. And it works well;
This days we try to modify the code with esp-idf Release 4.3-beta1.

And we found some strange logs during the tcp transmission;
09:43:16.994 I (67329600) wifi:bcn_timout,ap_probe_send ...

update the code with idf-4.3-beta1.
And after a long test, it works well.
May be we solved it.

Strange... your code itself looks good. What ESP-IDF version are you using? What else is your code doing?


Release 3.3.4
hardware :esp32-wroom-32

My code has almost 10~15 tasks ,and WIFI, LWIP and BLE.
And I will check the value in " spiTxBuf[0]" before put it in "spi_device_transmit";

For now ...

Sorry
now i have update the img and code
please check.

Esp32 works in spi master mode and keeps sending data to a spi slaver.
After more than 30 minutes,we found that sometimes the data on MOSI is different from the data which we put in "spi_device_transmit()".

Once the mismatch occurs. the scope stops and we take the picture like this:

hello everyone

when I debug the spi slave :

1.the function"spi_slave_transmit()": when i call this function,my spi data will in a queue.
My question is that if no master get the data,this data will always in queue,isn't it?
So i could not send a new data until some master get the old data.

2.how ...
