Each test message (uplink) consists of following data content:
(Proprietary “message sequence number” is a 16-bit value.)
Upper 4 bits are “main menu selection” identifier:
1h = Outdoor above 1m
2h = Outdoor 1m refer.
3h = Outdoor 0m ground
4h = Indoor
5h = Deep Indoor
Lower 4 bits are “measurement type” identifier:
1h = Survey 1x immediately
2h = Survey 1x delayed
3h = Final 6x immediately
4h = Final 6x delayed
5h = Downlink test
6h = Periodic measurement 1min + GPS
7h = Periodic measurement 10min + GPS
8h = Periodic measurement 60min + GPS
9h = Periodic measurement 10min no GPS
Ah = Periodic measurement 60min no GPS
Bh = Audit 100x immediately
Ch = Audit 100x delayed
For non-periodic measurements:
Number (1-255) of messages being sent in present test batch.
Actual message counter (1-255) = sequence number of message in present test batch.
For periodic measurements:
Batch sequence number (0-255). This value is incremented by 1 each time a batch is started by the user.
