preamble, and all radios will scan all frequencies for transmissions rather than expecting a
transmission on any particular channel. The default value is 185.
ID 54 through 59 – Reserved for Future Use
Reserved for future Synapse use.
ID 60 – Last Version Booted (Deprecated)
At one time the system tracked this to allow “test driving” a newer demo version of the firmware, even
after using up the “reboots remaining” with a previous version. The “demo policy” has since been
changed such that even a reload of the same version of firmware restarts the countdown.
ID 61 – Reboots Remaining
In a standard (signed, non-demo) build, this parameter is always 32767 (this is the closest we could
come to “infinity” in a 16-bit signed integer).
In a standard build, this value does not “count down.” Normally you have unlimited reboots.
In a demo build only, this value will “count down” with every reboot. When it reaches 0, the unit will
go into a “crippled” mode, in which it will not run (or even load) SNAPpy scripts, but can still be
“pinged.” (No, you cannot write to this parameter yourself to give yourself “more reboots.”)
ID 62 – Reserved for Future Use
Reserved for future Synapse use.
ID 63 – Alternate Radio Trim value
This is only used on some platforms. This parameter is not modified when you reset parameters to
factory defaults.
ID 64 – Vendor-Specific Settings
Similar in concept to NV parameter #11, but this field is reserved for non-standard settings. For valid
values, and their exact meaning, refer to the platform specific sections in section 10 of this manual.
This parameter is not modified when you reset parameters to factory defaults.
ID 65 – Clock Regulator
In platforms that have sleep modes that do not use a crystal, NV parameter 65 allows you to adjust the
regulation of the internal timer that controls sleep durations. The parameter does not apply to all
platforms. See the platform-specific section for your platform to determine how to best adjust this
value, if necessary. This value has no effect on sleep timings that are crystal-controlled.
ID 66 – Radio Calibration Data
In platforms that require extra calibration data for proper radio operation, NV parameter 66 is used to
store this calibration data. The parameter does not apply to all platforms. See the platform-specific
section for your platform to determine how to best adjust this value, if necessary.
