And as I said before, if you reset a device without closing the socket properly, the other end of the socket will keep waiting for the socket to become closed for some time until it timeouts. So either don't reset but close the socket properly or use UDP, which is designed for that use.
Maybe you have right, i try find solution for that.
So is a little strange, the same client on HLK module works perfect.
I will try close socket to the end of send data.
