FAQ
Carcell leftover questions
Does Carcell send an ACK?
No. There is no reply byte. A parsed lat/lon pair is the whole handshake.
What does a $ prefix mean on Carcell?
$ is a live fix. % is an archive fix. Both plot when lat/lon parse.
When does Carcell use CEL,?
CEL, switches to decimal latitude and longitude. Without CEL, the pair is hemisphere plus packed minutes.
Which CSV field binds a Carcell unit?
The IMEI immediately after the $ or % marker.
Can a Carcell unit run SMS setup or a controlled-action flow?
This dialect is positions only. There is no SMS family on this row.
