Member Function Documentation

void attach ( Callback< void(nsapi_event_t, intptr_t)>  status_cb)
inherited

The specified status callback function will be called on the network and cellular device status changes. The parameters on the callback are the event type and event-type dependent reason parameter.

Remarks
deleting CellularDevice/CellularContext in callback not allowed.
Allocating/adding lots of traces not recommended as callback is called mostly from State machines thread which is now 2048. You can change to main thread for example via EventQueue.
Parameters
status_cbThe callback for status changes.

This is equivalent to pulling the plug off of the device, i.e., detaching power and serial port.

This puts the modem in the lowest power state.

Remarks
CellularStateMachine disconnect or destruct does not shutdown or power off the modem, but you need to do that yourself.
Precondition
You must call soft_power_off to power off the modem before calling hard_power_off.
Returns
NSAPI_ERROR_OK on success

Implements CellularDevice.

Reimplemented in TELIT_ME310, TELIT_ME910, and QUECTEL_EC2X.

virtual nsapi_error_t hard_power_on ( )
virtualinherited

Sets the modem up for powering on This is equivalent to plugging in the device, i.e., attaching power and serial port.

In general, hard_power_on and soft_power_on provides a simple hardware abstraction layer on top of the modem drivers written for Mbed OS; they can be overridden in a derived class to perform custom power controls in a particular board configuration. In many boards this will be a no-op if there is no separate power supply control circuitry.

Remarks
CellularStateMachine calls hard_power_on at first until successful, then soft_power_on and init until the modem responds. If you are not using CellularStateMachine then you need to call these functions yourself.
Postcondition
You must call soft_power_on to power on the modem after calling hard_power_on.
