  • Page 12: Network Registration

    Network Registration Here below a brief overview of 4G (CAT M1, NB IoT) and 2G (GPRS) registration process, IP stack setup and related commands. 4G registration (CAT-M1, NB-IoT) and IP stack setup: the module performs Attach and EPS Bearer activation automatically. When the procedure ends an IP address is assigned by the network to the module.
  • Page 13 New attach is needed to use the new APN. A way to do this is to turn the radio off and on using AT+CFUN AT+CFUN=4 AT+CEREG? +CEREG: 0,0 AT+CFUN=1 AT+CEREG? +CEREG: 0,0 AT+CEREG? +CEREG: 0,2 AT+CEREG? +CEREG: 0,1 AT+COPS? +COPS: 0,1,"I TIM",9 AT+CGCONTRDP +CGCONTRDP: 1,5,"nbiot.tids.tim.it","10.16.13.162",,"192.168.200.43","192.168.200.42"...

  • Page 16: Speed Up Registration

    4.4 Speed up registration The registration process in CAT-M1 and NB-IoT technologies could require some minutes to complete. This happens especially in the case of very first registration: new SIM, new location, new module. This is due to the IoT technology itself and cellular network deployment factors. To speed up the process you can reduce the set of supported technologies and bands.

  • Page 17: Check/Set Data Service

    5 Check/Set data service When registration is completed you can activate data services and set up the internal IP stack with the AT#SGACT command: AT#SGACT=<cid>,<stat>[,<userId>[,<pwd>]] E.g. if we want to activate context 1, issue AT#SGACT=1,1; in case we want to use the <cid> 3 (e.g.

The goal of these features is to reduce the power consumption of IoT devices.

  • Page 23: Psm Script

    Both features require a negotiation with the network to be enabled. The negotiation happens during the Attach procedure and the Tracking Area Update (TAU). PSM script The module supports 3GPP command AT+CPSMS and custom Telit command AT#CPSMS that simplifies and improve PSM management.
