Hi all,
I'm working with a custom stm32f767 based board and px4 project fork with
nuttx-10.0.0+ and uploading data (~900KB) to the board using mavlink_ftp.
If mavlink is over serial port everything is fine and long transfer going
uninterruptedly, but if mavlink is over UDP link the ftp file trans
Hi Oleg,
Did you try to tune the configs? Try to increase the buffers size, etc.
BR,

Hello Oleg,
Can you try to test with "CONFIG_NET_UDP_WRITE_BUFFERS=y" vs
"CONFIG_NET_UDP_WRITE_BUFFERS=n"? The transfer will definitely impact the
speed, but at least we can have a idea if buffer allocation impacts the
upload process or not.
Best regards,

Packet loss is normal UDP behavior (unless it is excessive). If you use
UDP, you application design must handle occasional packet loss gracefully.
In order to debug this further, you will need to enable network statistics.

Buffering issues is the most common cause of major packets losses. That
would make sense in you case because enabling DEBUG has the effect of

Hi,
Yes, the packet lost on UDP is a normal situation, but... If the board is
directly connected to the PC, then from my experience the probability to
lose a UDP packet in the wire is pretty low. So only loss may be done in
the stack and statistics should identify this easily.
