I have ATSAME MCU and ESP32. I used ready to use esp-idf examples to create tcpip client in eclipse with ESP32(standalone) and its working great.
Now, I want to make a tcp_client using ESP32 module together with ATSAME53. ATSAME will be acting as the main MCU and I want to create a client using netconn APIs in lwip which will be in ATSAME. ESP32 uart pins connected to uart pins in ATSAME. I want ESP32 to be just bridge and give data from the router(internet) to ATSAME which will use lwip to process it and create a netconn client. (ESP-->ATSAME) I changed inside wlanif_input(struct netif *netif, void *buffer, u16_t len, void* eb) function in ESPlwip and send the buffer(packet) to ATSAME using uart(instead of tcpip_thread). I want packets to be processed in ATSAMElwip. When I received packets from ESP32 in ATSAME side, I called tcpip_input(p, &TCPIP_STACK_INTERFACE_0_desc) to send it to tcpip_thread to be processed. (ATSAME-->ESP) Coming packets from ATSAMElwip were sent to esp32 using netif->output= etharp_output fn which was modified to send using uart. Received pacets in ESP were sent to wifimodule using low_level_output function and sent using esp_wifi_internal_tx(wifi_if, q->payload, q->len); *But I have problems with creating netif. Shall I have two separate netifs(one in ESP and one in ATSAME), are two netif equally important? *Is it possible to realize whats in my mind? -- Sent from: http://lwip.100.n7.nabble.com/lwip-users-f3.html _______________________________________________ lwip-users mailing list lwip-users@nongnu.org https://lists.nongnu.org/mailman/listinfo/lwip-users
