13. Diagnostic Provisions
13.1. Overview of Diagnostics
Internal to the
M8S
radio modem, is a powerful 32-bit microprocessor. Along
with handing all aspects of radio modulation and demodulation, the
microprocessor also maintains an extensive array of diagnostic information.
This section details the diagnostic information available, and describes how to us
the information to optimize or troubleshoot a
M8S
radio network.
13.2. Reading the Diagnostic Information
M8S
diagnostic information is read using AT commands, while the unit is in the
Command Mode. Refer to the section “User Serial Port Commands” to learn
how to put the
M8S
modem into the Command Mode.
To see a general overview of how the modem has been operating, us the
ATST
command (status request command), without any parameter. The radio modem
will respond with a list of certain operation statistics that it maintains. All statistics
start counting at 0. The
ATST 1
command can be used to reset all statistics
back to 0, except the run-time timers.
Other operation and configuration statistics are available using the ATST
command, with a parameter to specify the desired statistic. The following table
describes the various statistics available.
