I have a memory that it is possible to drive a gpio pin in a Tinytrak 4 high or low based on the receipt of an over the air command in an APRS packet.? I have looked at the manuals and this mailing list but can't find anything. I am looking to drive a relay to switch a repeater on and off at a remote mountain site which is battery powered.? Is my memory more faulty than usual?? Could someone point me to some doco on this.
Hi Steve,
Are you referring to this, perhaps? A passing mention on page 2 of the Alpha firmware doco:
The TinyTrak4 Alpha firmware can also react to incoming messages directed toward it, regardless if
the display and keyboard are used. These messages include the ability to request a position report,
and to remotely control digital outputs.?
I can¡¯t say I¡¯ve tried it, but the capability appears to be there. However, I didn¡¯t see any other mention of this capability in the manual.
