Send a formatted AT command to the modem and receive the response asynchronously via a callback.

This function waits for the Modem to acknowledge the AT command but will return without waiting for the command execution.

Note

The callback is executed in an interrupt context. Take care to offload any processing as appropriate.

Parameters

callback	Callback to receive the response.
fmt	Command format.
...	Format arguments.

Return values

0	On "OK" responses.
-NRF_EPERM	The Modem library is not initialized.
-NRF_EFAULT	callback or fmt are NULL.
-NRF_EINVAL	Bad format fmt.
-NRF_EINPROGRESS	Another AT command is executing.
-NRF_ENOMEM	Not enough shared memory for this request.
-NRF_ESHUTDOWN	If the modem was shut down.
