BG77 driver error type

Variants

NoSocketAvailable

All sockets in use

PinRequired

It looks like a pin is required to unlock the SIM card.

CgattFailure

Internal error: Even though the operator selection succeeded, the modem does not look connected afterwards.

SocketAlreadyConnected

Trying to connect a socket that is already connected

OpenSocketError

Could not open socket (modem did not answer, answer could not be parsed or modem answered with an unexpected message).

IPv6Unsupported

An IPv6 IP address was used but IPv6 is not supported (yet?). This error originates from the fact that we use the (external) embedded-nal::<Protocol>ClientStack traits which accept both IPv4 and IPv6 addresses so we can not prevent this kind of error statically.

NotConnected

Trying to send or receive data when the socket is not connected.

Hardware

An error occurred when accessing the underlying hardware (gpio or serial)

AtCmdTimeout

An AT command timed out

AtCmdError

The modem responded to an AT command with “ERROR”

AtCmdCmeError

The modem responded to an AT command with “+CME ERROR: …”

BufferOverflow

An internal buffer was not big enough to handle the amount of data

TxSize

The tx data size exceeds the maximum supported tx data size (1460 bytes)

ReverseDnsUnsupported

embedded_nal::Dns::get_host_by_address() was called which is not supported

ParseIpAddressFailed

The resolved IP address could not be parsed into a embedded_nal::IpAddr

ParseFailed

A value could not be parsed into a specific type, e.g. the modem answer (bytes) could not be parsed into an integer.

RxSize

The modem returned more rx data than the maximum amount of data we requested / can handle.

Trait Implementations

impl Debug for Bg77Error

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for Bg77Error

fn eq(&self, other: &Bg77Error) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl TcpError for Bg77Error

fn kind(&self) -> TcpErrorKind

Determines the kind of error that occurred.
