Connecting the Quectel BGxx module to a LwM2M server

AnyNet SMARTconnect™ uses the essential AnyNet files to connect a Quectel BGxx module to a LwM2M bootstrap server. For more information, see Creating the essential AnyNet files.

AnyNet SMARTconnect™ then obtains the certificates and data required to connect to a LwM2M server from the LwM2M bootstrap server. There are two modes for the connection:

• Secure – CoAP messages are encrypted using a DTLS connection.
• Non-secure – CoAP messages are exchanged unencrypted via UDP.

About LwM2M certificates

After the bootstrap procedure completes, for secure mode, AnyNet SMARTconnect™ saves these files in the datatx folder:

• lwm2m_server_public_key – the x509 server certificate
• lwm2m_public_key – the LwM2M public certificate
• lwm2m_secret_key – the LwM2M public private key
• lwm2m_url – the LwM2M server URL, in this format:

  coap(s)://<server>

  coaps indicates secure mode. coap indicates non-secure mode.

  If coaps is used, but a LwM2M file is missing, non-secure mode is used.

  For non-secure mode, only anynet_thingname_store and lwm2m_url are required.

LwM2M files require the same six-byte header as the essential AnyNet files. For more information, see Creating the essential AnyNet files.
