MC8355 Offline without Callback

IoT Modules MC/EM Series
1

We’re working with the MC8355 using firmware version D3600-STSUVHZ-1579 (Verizon) and seems to be having persistent problems where the device will go offline, but not fire the session state callback. Also, calls to GetSessionState are returning the 2 (session up). However, when we attempt to poll the IP address using udhcpc (dhcp client), it doesn’t respond.

Then we force a disconnect (and subsequently get the session state callback fired with disconnected), it won’t allow a reconnect without cycling the RF.

We’re using a connection manager similar to the one provided in SDK 1.09.04, which is the SDK we’re currently operating off of. Any ideas?

Hi,

In the QMI SDK,it is mentioned that for states : suspended state is not supported.

so the callback is not called for sessionstatecallback()API.

Thanks.

How is it possible to tell the session state is suspended?
