Using Configuration Commands
All printable characters can be entered directly via the keyboard. Any
non-printable characters are entered in binary data format.
Numbers are in decimal format except numbers with:
• an h suffix are in hexadecimal
• a “0x” prefix are in hexadecimal
• a “b” suffix are in binary
Binary data format is any non seven-bit ASCII data to transmit to the
module is encoded in the Internet percent notation. Any hex byte to
transmit is preceded by the “%” sign and encoded in hex ASCII. To send
the value 0xF5, the “%F5” bytes are transmitted. The “%”character is
always transmitted as “%25”. Thus, a Bluetooth address could transmit
as “%00%E0%03%45%F4%6D”.
Generic format:
<command character><command type><command payload><CR>
<command character> is one character from the set: [A-Z]
<command type> is one character for the set: [0-9]
<command payload> is variable in length.
<CR> is the command terminator.
The <command payload> is formed from printable ASCII characters
from the code range 0x20 to 0x7E.
Codes outside of this range are escaped using the percent (%) character
followed by two hexadecimal digits.
The percent character is always represented by the three characters %25.
The command terminator is character code 0x13 (carriage return), or
character code 0x10 (line feed), or character codes 0x13, 0x10 (carriage
return, line feed).
An example command to set the friendly name to “Len’s 100% serial
module”:
F0Len’s 100%25 serial module<CR>
Character codes outside of the range of 0x20 to 0x7E are ignored.
When using percent (%) to form hexadecimal character codes there must
be exactly two hex digits using characters: [0-9, A-F, a-f]. Characters
outside of this range cause the command to fail.
