I use lwIP-1.3.2, FreeRTOS 7 HW: stm32 micro, GSM modem. Stack works via PPP. When I am sending a few data (up to ~10kB)from server to board it recceived perfetly. But when I sent larger (30kbytes) array to board, I discovered that stack received only 9 frames (1360 bytes of usefull data in each). Modem simply dont send more frames (because obviously server dont like the 9th ACK). Application have no memory leakage, moreover the memory size have no effect on its behavour. FreeRTOS 92% of time in IDLE.
After board make some transmitions to server - server begins to finish the transmition of the rest of 30k-array. After it finished, application works fine again. I tryed another modem, I changed almost all options of lwIP but have no effect. What I do wrong?%-| http://old.nabble.com/file/p32697256/sio.c sio.c http://old.nabble.com/file/p32697256/lwipopts.h lwipopts.h Thanks -- View this message in context: http://old.nabble.com/lwIP-1.3.2-PPP-problem-on-large-arrays-recceiving-%28FreeRTOS%29-tp32697256p32697256.html Sent from the lwip-users mailing list archive at Nabble.com. _______________________________________________ lwip-users mailing list [email protected] https://lists.nongnu.org/mailman/listinfo/lwip-users
