1) I tried checking tcp_sndbuf, but I doubt it is the answer, for the
thruput rate is way too low, and I can send much more error-free without it
2) When I lwip_send too much data, the program actually crashes --- I will
investigate more on the cause

I don't think such a function is available as part of the sockets API.
By "hang", do you mean "block", or does something go seriously wrong?
