LwM2M Bootstrap Server Fails to Provision Device

In this tutorial, you'll learn about LwM2M Bootstrap Server Fails to Provision Device. We cover key concepts, practical examples, and best practices.

The Problem

LwM2M bootstrap session fails and the device is not configured.

Quick Fix

Wrong

// No bootstrap server configured
anjay_bootstrap_install(anjay);
anjay_start(anjay);```

Device fails to bootstrap. Server URL and credentials not configured.

### Right

```cpp
#include <anjay/anjay.h>
#include <anjay/bootstrap.h>

int main(void) {
  const anjay_configuration_t config = {
    .endpoint_name = "urn:dev:001:my-device",
    .in_buffer_size = 4000,
    .out_buffer_size = 4000
  };
  anjay_t *anjay = anjay_new(&config);

  // Install bootstrap object (ID 16)
  anjay_bootstrap_object_install(anjay);

  // Configure bootstrap server
  anjay_bootstrap_register(anjay, "coap://bs-server:5783", 60);

  // Start
  anjay_start(anjay);

  while (true) {
    anjay_sched_run(anjay);
  }
}```

Bootstrap session initiated. Server provisions security credentials and server config.

## Prevention

LwM2M Bootstrap (Object ID 16) initializes devices with first-time configuration. The bootstrap server provisions Security Object (ID 0) and Server Object (ID 1) settings. Bootstrap can be: factory bootstrap (pre-configured), client-initiated (device requests bootstrap), or server-initiated (server triggers). Bootstrap uses port 5783 by default.

DodaTech engineers apply these same patterns across Doda Browser, DodaZIP, and Durga Antivirus Pro for production IoT reliability.
