Extended Bolus

6,0 Unit total bolus: 2,0 Units immediate, 4,0 Units over 3 hours

1a 16 01e475cb 02 0129 07 0280 0028 0028 100d 000e 100d 000e 17
  • 1a Insulin Schedule Command
  • 16 Length of bytes
  • 01e475cb Nonce
  • 02 TableNum = 2, Bolus type
  • 0129 Checksum, byte sum of next 3 fields and the resulting insulin schedule table of [$28 $d $d $e $d $d $e]
  • 07 # of entries in the resulting insulin schedule table (1 for immediate bolus plus 6 for 3-hour extended bolus)
  • 0280 Field A, First InsulinScheduleElement value of 0028 * $10
  • 0028 UnitRate, First InsulinScheduleElement value of 0028 (# of ticks to deliver immediately?)
  • 0028 InsulinScheduleElement resulting in 1 entry of [40] * 0,05U = 2,0U immediate bolus
  • 100d N=1+1 = 2 entries (1 hour) of [13 13] = 1,3U
  • 000e N=0+1 = 1 entry (0,5 hour) of [14] = 0,7U
  • 100d N=1+1 = 2 entries (1 hour) of [13 13] = 1,3U
  • 000e N=0+1 = 1 entry (0,5 hour) of [14] = 0,7U
  • 17 Fixed next command for all bolus commands

The resulting 7 Entry Insulin Schedule Table is [40 13 13 14 13 13 14]. The first 40 tick entry delivers the 2,0U immediately, while the remaining 6 entries deliver a total of 13+13+14+13+13+14=80 ticks * 0,05U/tick = 4,0U over the next 3 hours for the extended bolus.
