I came across issue of UART_BUFFER_FULL while soft reboot. This issue is not seen in hard reset (unplug cable). I have tried option of Uart flush, reseting queue, I still see this problem. I also tried adding delay at the beginning of boot. Do you have suggestion, where to look ...

Re: uart 接收数据长度限制问题by Yake » Tue Nov 02, 2021 2:53 am 改动UART_FULL_THRESH_DEFAULT 的值是没有意义的,因为 ESP32 的 FIFO 只有128字节,默认在接收到120字节之后会触发中断,自动将数据转存到上层的 Buffer 里面去,因此,你只需要把上层的 buffer 改大即可。 UART 的驱动会自动缓存数据到 ...
