//
// Usage:
// 1. Visit https://mongoose.ws/wizard. Enable MQTT, generate project
// 2. Copy-paste this code into your main.c
// 3. After mongoose_init() call, add initialization:
//    struct mongoose_mqtt_handlers mqtt_handlers = {
//        my_mqtt_connect,    my_mqtt_tls_init, my_mqtt_on_connect,
//        my_mqtt_on_message, my_mqtt_on_cmd,

How to add Mongoose to NetX Duo, STM32 H573

Video: https://mongoose.ws/downloads/mongoose_netxduo.mp4

1. Load Nx_TCP_Echo_Server example for STM32H573II Add IO retargeting to main.c:

int _write(int fd, unsigned char *buf, int len) {

cpq

size_t print_entries(void (*out)(char, void *), void *ptr, va_list *ap) {
  const char **names = va_arg(*ap, const char **);
  size_t i, len = 0;
  for (i = 0; names[i] != NULL; i++) {
    len += mg_xprintf(out, ptr, "%s%m",
                      i > 0 ? "," : "",   // Comma-separate entries
                      MG_ESC(names[i]));  // JSON-escape string
  }
  return len;
}
