Does nRF9160 support multiple LWM2M connections?

[BitManu]

Can I connect nRF9160 simultaneously to multiple LWM2M servers?

i.e. connecting the device concurrently to operator (lwm2m_carrier) and to my own server (lwm2m_client)

If I can simultaneously connect to several LWM2M servers, what is the limit of the nRF9160 LWM2M engine connections?

Hi, BitManu!

I will have to ask the developers about this, but I won't expect an answer before next week due to the holidays. Apologies for the inconvenience and happy new year!

Best regards,

Hi again, BitManu!

It is possible to use the lwm2m_carrier library and the lwm2m_client simultaneously, meaning that you can connect to the operator and your own server concurrently. However, I believe this is the limit as the lwm2m_client only supports one server.

The modem supports "Up to three simultaneous TLS/DTLS connections", which enables a potential for one more connection, but there could be RAM limitations on the modem side.

Hope this answers your question!

Best regards,
