You mentioned there is no tcp retransmission, and i assume your STM32L4
is good, the packet loss should happen on the UART transmission.
Could you please enable the uart hardware flow control by adding CTS/RTS line here, and enables it by sending AT+UART_CUR=230400,8,1,0,3
from esp-at.
@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
from esp-at.
@venkateshdhara If you have already enabled hardware flow control and other conditions outside are right, this should be a bug.
Could you please use latest master branch and enable more logs to see what happened:
python build.py menuconfig -> Component config -> Log output -> Default log verbosity -> Debug
python build.py menuconfig -> Component config -> AT -> Enable ESP-AT Debug
python build.py menuconfig -> Component config -> AT -> Enable ESP-AT Debug -> Enable Network Debug
(Disable BT to reduce bin size) python build.py menuconfig -> Component config -> Bluetooth -> Deselect
The AT log port output should give more logs.
