Subject: altos: Use 0x80 to indicate valid state value in the GPS location packet
X-Git-Tag: 1.3.2.4~10
X-Git-Url: https://git.gag.com/?p=fw%2Faltos;a=commitdiff_plain;h=08550425fca3da73d8f16de567a2c956b85d676e;hp=d8b271502bfd1301b2244e3be5e8c9917a9c624a

altos: Use 0x80 to indicate valid state value in the GPS location packet

And only set this for tracker products; other products place state in
separate state packets
