Kieth, since LDRS is 4 days away, no programs can "secure" a link, or password protect a unit.(I am not that good anyway.....)
Perhaps, a Farmerware version could be easily done with just removing that module of programming for him. Leave altos alone, but make is telemetrum, not respond to "fire charge" I am not familiar with everything else that would foil. This would be a quick fix to help John, probably not an issue but for the bigger launches. And afterward, you could revert the firmware back to standard if you wanted to test a new rocket.

Nope; if there's someone you know who is interested in making that a configurable option, the source code is all available. > Several folks in our club are buying this unit, and we sometimes help each > other track with multiple teledongles. on one such occasion I powered up my > telemetrum and one of my fellows jokingly offered to test fire my ejection > charges for me. since then I have waited to power the rocket up in pad mode, > just in case there is a jerk on the field. has there been any thought to > pass wording or otherwise limiting who can fire ejection charges or make > changes through the telemetry system? Yeah, at least a way to limit the communication to a single serial number or something. That would at least avoid accidental stuff of this nature. I've built a prototype launch controller using the built-in AES engine to secure the link; we could use something like that for radio link, but it would leave you with the usual key distribution problem (getting the same shared secret to multiple devices is a pain). > See you all at LDRS & BALLS, Bdale and AJ will be at LDRS; vendor booth #19! -keith _______________________________________________ altusmetrum mailing list [email protected] http://lists.gag.com/mailman/listinfo/altusmetrum
