We are developing a system were we rely heavily on the use of LWM2M. Using the provided LWM2M client we normally dont experience any problems at all and are able to establish a quick server connection. We recently exchanged our SIM provider and the corresponding apn and are now experiencing way longer server connection establishment times (Multiples of 123 seconds). Looking into the Modem Logs we figured that the TLS Handshake with the RPC_IP_TLS_ATTACH_RES (result RPC_IP_ERR_OK) and the RPC_IP_TLS_HANDSHAKE_COMPLETE_NTF (result: RPC_IP_ERR_NO_ROUTE) might be the culprit here. As I dug into the documentation i figured out that there are many different timeouts for the TLS Handshake.
My question now is wether there is a working way to configure the timeout in combination with the Lwm2m engine or any other way or if there is another suitable solution for the DTLS problem.
Unfortunately I cant provide modem traces atm because they require more RAM than available.
Thanks in advance for the help,
Flo
