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

●

ErrExecution

●

ErrFormat

●

ErrInProgress

●

ErrInvalidParam

●

ErrNumParam

●

ErrUnknownCmd

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

replace the original error response

AT-AB ErrorCommand

D.1

ErrConnect

The ErrConnect error response will be sent if abSerial 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.

Table 10.

Example commands that generate <ErrConnect>

Example

Reason

AT+AB security none

Changing security level while a connection is up.

AT+AB discovery

Performing a device discovery while a connection is up.

AT+AB SPPConnect

00043e000000

Establishing a connection to a device while a connection is exists

with another.
