Hi All,
I am trying to upload a file from my target board.
I use tcp socket (My client code) to send data using HTTP POST to
the remote apache server using ppp link.
I have proper connectivity. My client code sends data to pppd over
ttyU0 (virtual serial port on ussp driver) which forwards the data to
cmux (gsm0710) driver which inurn gets transmitted to the Modem.
I observed that when ever I send a file size greater than 255 bytes
the data transfer takes a long time. The remote server times out and
send HTTP error code 500.
I enabled the debug level of CMUX and USSP driver according to it the
data reaches to them after a long delay from PPPd .
How do I fix this ? Can I print PPP packets ? I don't have pppStats
facility for pppd. Even, I don't have debug option support in my pppd.
