I tried to write several times and to write more in 1 pack (but not
both). I get results only in fifth reading. So I removed printf and
added cycle so:
5000 times:
modify sent[]
write 64 bytes
read till length == 34 or up to 6 times
fail if read 6 times
check results
It does not fail. 5k iteration take 6.1 seconds, so transfer speed is
52kb/s. Code attached.
Thanks!
