Command Summary
Description
AT Command: ATRS
<Diagnostics> RS Command returns the
signal level of the last packet
received. This reading is useful for
determining range characteristics of the
modules under various conditions of
noise and distance.
Once the command is issued, the
module will return a value between 0x6
and 0x36 where 0x36 represents a very
strong signal level and 0x4 indicates
a low signal level.
Binary Command: 0x1C (28 decimal)
Parameter Range: 0x06 – 0x36 [read-
only]
Number of bytes returned: 1
