Lost byte's #40

Closed JoeReturn closed 8 months ago

Dear Hideaki Tai,

I have been trying to use the ESP32 library you created for some time, but it doesn't seem to work properly. I am attaching a source code in which there is both TCP and SPI slave communication.

The issue is that, in the master SPI device, the first 168 bytes (from 4108) are consistently missing in a loop, and I don't really understand what kind of error could cause this.

Thank you for your response.
