BC95 AT Commands Manual
BC95_AT_Commands_Manual Confidential / Released 7 / 58
When entering AT commands spaces are ignored except in the following cases:
Within quoted strings, where they are preserved;
Within an unquoted string or numeric parameter;
Within an IP address;
Within the AT command name up to and
including a „=‟, „?‟ or „=?‟.
They can be used to make the input more human-readable. On input, at least a carriage return is required.
A newline character is ignored so it is permissible to use carriage return/line feed pairs on the input. For
B600, the AT command processor uses carriage return/line feed pairs (\r\n, 0x0D0A) to end lines on its
output.
If no command is entered after the AT token, OK will be returned. If an invalid command is entered,
ERROR will be returned.
Optional parameters, unless explicitly stated, need to be provided up to the last parameter being entered.
1.3. AT Command Responses
When the AT Command processor has finished processing a line, it will output either OK or ERROR
indicating that it is ready to accept a new command. Solicited informational responses are sent before the
final OK or ERROR. Unsolicited information responses will never occur between a solicited informational
response and the final OK or ERROR.
Responses will be of the format:
<CR><LF>+CMD1:<parameters><CR><LF>
<CR><LF>OK<CR><LF>
Or
<CR><LF><parameters><CR><LF>
<CR><LF>OK<CR><LF>
1.4. 3GPP Compliance
3GPP commands are complied with the
3GPP TS 27.007 v13.5.0 (2016-06)
