Comments
You mentioned there is no tcp retransmission, and i assume your |
@ustccw i have done this experiment by using qcom terminal sending message to hurceles software(tcp server) and receiving echo with 5sec interval still i see packet loss, i have done this experiment before seeing your comment but i did this at 115200 with hardware flow control CTS/RTS |

General issue report
I am using ESP32-C3 and experiencing packet loss in reception in TCP and transmit is always good, following methods are debugged
system is setup in such a way ESP32 is connected to stm32l4 MCU and exchanging data every 5seconds with raspberry pi
1.Ran TCPDUMP service in RPI there is no tcp retransmission request observed.
2.ESP32 using in UART 115200 tried changing baud rate 230400.
3.Tried CIPRECTYPE=1. passive mode
4.probed logic analyzer on UART and confirmed data was not received on UART.
5.KEEPALIVE value 3 sec
6.used quick configuration to increase throughput as suggested in FAQ page
