Hi,
Is there a reason why the LCP echo data type size is u8?
u8_t fsm_timeout_time;/* Timeout time in seconds */
u8_t fsm_max_conf_req_transmits; /* Maximum Configure-Request transmissions
*/
u8_t fsm_max_term_transmits; /* Maximum Terminate-Request transmissions
*/
Hi,
I have turned off PPP_DEBUG and LWIP_DEBUG 0.
I can see in netif/ppp/lcp.c and netif/ppp/ppp_input that ppp_dbglog is used
instead of LCPDEBUG.
It looks like they need to be changed to LCPDEBUG to silence the debug and not
call ppp_logit.
void ppp_dbglog(const char *fmt, ...);/* log a
en once a day but signals and alarm to the SCADA
system and isn't acceptable.
Attached a snapshot.

Hi Simon,
When (LWIP_CHKSUM_ALGORITHM == 1) the function isn't the same as the function
definition and uses a u16_t.
Below is the error:
../src/lwip/core/inet_chksum.c:82:1: error: conflicting types for
'lwip_standard_chksum'
lwip_standard_chksum(void *dataptr, u16_t len)

Hi Sylvain,
At what case does your sio_read returns len < 0 ?
while(1) {
u8_t buffer[128];
int len;
len = sio_read(fd, buffer, 128);
if(len < 0) {
pppapi_sighup(ppps);
} else {
pppos_input(ppps, buffer, len);
}

Hello Simon,
I have noticed in the latest git version when LWIP_CHSUM_ALGORITHM == 1 it
produces a conflicting type error for the function:
u16_t lwip_standard_chksum(void *dataptr, int len);
the function is:
lwip_standard_chksum(void *dataptr, u16_t len)

It is the new PPP stack sylvain has updated. You need to grab the latest
source code from git. It's not in 1.4.1

. With NETCONN_COPY, the lwip creates

Could you provide a detailed description of your configuration, like

I believe it has to do with your ethernet driver and how it is implemented.
Even if you send data to your hardware you should control this with a
incrementer for example just like a round robin.

Hi Sylvain,
Ok I followed your suggestions and it works nicely. I just call ppp_close
and don’t delete the thread. When I want to reconnect I call ppp_reopen and
it simply changes the netif interface to match the new ip. I also removed
the sys_msleep(1) and added a semaphore to the uart rx int
Hi Sylvain,
Thank you for the pointers. If I don’t delete the pcb and just call
ppp_close and when Im ready to send data re-start the process what should I
do? I could use the ppp first created.
I need to stop the GSM modem as the device will go in a sleep environment
and send for example ever
Hi Sylvain,
Ok I think I found the problem. I use PPP_INPROC_OWNTHREAD and once I added
ppp_delete() to the end it seems to fix the problem.
I also removed the ppp_delete from the linkStatusCB. Somehow a clean up wasn’t
completed and a pbuf was always allocated but not freed as you can here:
Hi Sylvain,
I added ppp_free_current_input_packet() inside ppp_delete but the problem
still remains.
