Error responses

This chapter details the error responses that occur under specific circumstances.

There are seven error responses that can occur beyond error responses specific to a

particular command (e.g., Discovery). They are:

•

ErrConnect

•

ErrExecute

•

ErrFormat

•

ErrInvalidParam

•

ErrNumParam

•

ErrUnknownCmd

•

ErrInProgress

The following subsections detail the different error responses. These error responses

replace the original error response

AT-AB ErrorCommand

4.1

ErrConnect

The ErrConnect error response will be sent if ATn FW has a valid connection established

and the command cannot be executed while connected (even in the command mode).

Examples of commands that produce this error response are given in the following table.

4.2

ErrExecute

The ErrExecute error response will be sent if the command cannot complete for any reason.

Examples of commands that produce this error response are given in the following table.

Table 3. Example commands that generate <ErrConnect>

Example

Reason

AT+AB Discovery

Performing a device discovery while a connection already

exists.

AT+AB SPPConnect 00043e000000

Establishing a connection to a device while a connection

exists with another.

Table 4. Example commands that generate ErrExecute

Example

Reason

AT+AB Sniff

Execution of sniff while the device is not connected
