  • Hi, sorry for the late response.

    Attaching a plot of:

    • Modem waking up from offline mode
    • Scanning for networks
    • Attaching to the network
    • Sending 100 bytes of data and staying in RRC connected mode with 320ms DRX intervals (waiting for any response from the network)
    • Then goes to PSM (power saving mode, consuming 4 uA)

    Complete event:

    Scanning:

    Connected:

    Staying in DRX mode (discontinuous reception), waiting for incoming data. This length is decided by the network and may be longer or shorter than shown here:

    PSM mode. Power saving mode. Do not have to scan for the network again upon waking up:
