Entering to command mode - +++
Entering to command mode is performed when device gets three (3)
‘
+
’ characters in a row.
Between characters needs to be a delay of three (3) characters. In this way device can decide
that it is required to enter command mode
after three correct characters. First two (2) ‘
+
’ –
characters is transmitted by radio, because device cannot know at this point whether the last
character is correct. After successfully given command mode entering syntax, device responds
“
OK<CR><LF>
”. Below is a figure to entering command mode.
Delay between characters depends what is the current serial baud rate. See specifications of
three (3) character delays below in “
Table 1. Delay in different baud rates
”
.
11.2.2
Return to data mode - ---
When command mode is active
, it is possible to return in normal data mode by giving three (3) ‘
-
’ –
character in a row. Sequence is same as entering to command mode, so there is also needed
three (3) characters delay between sending the characters. After successfully given exit
command mode syntax, device responds “
OK<CR><LF>
”. Below is a description how to exit
command mode.
Delay between characters depends what is the current serial baud rate. See specifications of
three (3) character
delays below in “
