Pod Progress State

Pod Progress State

The Omnipod keeps an internal Progress State variable that starts at 0 and advances to a maximum value of 15. Internally this value is stored as a set of 16 bits, but this value is always accessed by using a routine that finds the highest bit that is set to indicate the progress of the Pod. This 4-bit Pod Progress State value is included within many of the responses: 01 Version Response, 02 Type 2 Fault Response and 1D Status Response.

• 0: Initial value
• 1: Memory initialized
• 2: Reminder initialized
• 3: Pairing completed
• 4: Priming
• 5: Priming completed
• 6: Basal initialized
• 7: Inserting cannula
• 8: Running with > 50U (normal)
• 9: Running with <= 50U (low reservoir mode)
• 10: Not used
• 11: Not used
• 12: Not used
• 13: Fault event
• 14: Activation time exceeded
• 15: Pod inactive

A Pod will pass through states 1 thru 7 during the Pod activation process and then will be in state 8 for normal use. The vast majority of a typical Pod's active lifetime is spent in states 8 and perhaps 9 if the reservoir drops to 50 U.

For many commands, the Pod must be at one of the correct Pod Progress States for that command or the command will fail or the Pod will fail, typically with a 049 (0x31) fault.
