When I am connecting a Pico W with the example from VSCode Raspberry Pi project (polled lwIP or backgroud lwIP):
it succeeds only every second time. "WiFi init failed" in the other times. This "WiFi init failed" appears only some seconds after the connection was started, not after the 30s timeout. I assume, that the connection process starts and there is no internet number supplied by the Fritz-Box (AVM DSL-Router). If I try cyw43_arch_wifi_connect_async instead of cyw43_arch_wifi_connect_timeout_ms it connects every time without error, but every second time the IP-number is 0.0.0.0.
When I am using Micro-Python with this Pico W and my Fritz-Box, the example task from connecting-to-the-internet-with-pico-w:
works without any problems and seems to be very quick.
Code:
#include <stdio.h>#include "pico/stdlib.h"#include "pico/cyw43_arch.h"int main(){ stdio_init_all(); // Initialise the Wi-Fi chip if (cyw43_arch_init()) { printf("Wi-Fi init failed\n"); return -1; } // Enable wifi station cyw43_arch_enable_sta_mode(); printf("Connecting to Wi-Fi...\n"); if (cyw43_arch_wifi_connect_timeout_ms("SSID", "Password", CYW43_AUTH_WPA2_AES_PSK, 30000)) { printf("failed to connect.\n"); return 1; } else { printf("Connected.\n"); // Read the ip address in a human readable way uint8_t *ip_address = (uint8_t*)&(cyw43_state.netif[0].ip_addr.addr); printf("IP address %d.%d.%d.%d\n", ip_address[0], ip_address[1], ip_address[2], ip_address[3]); } while (true) { printf("Hello, world!\n"); sleep_ms(1000); }}When I am using Micro-Python with this Pico W and my Fritz-Box, the example task from connecting-to-the-internet-with-pico-w:
