This release brings a few changes to current factory firmware:

  • Default advertisement interval is now 0.5 Hz / 2000 ms
  • URL mode is deprecated and replaced by RAWv2 mode (data format 5).
  • Tag has 3 modes: RAWv1, RAWv2, RAWv2_slow.
  • Slow mode advertises at 6000 ms interval to save battery
  • RAWv1 consumes ~15 uA, and should last for 6 years
  • RAWv2 consumes ~18 uA, and should last for 5 years
  • RAWv2_slow consumes ~13 uA and should last for 7 years
  • Tag reboots after NFC read to work around occasional hang after NFC read
  • Mode is stored to flash and read from flash after reboot.
  • Long press on button "B" enters DFU mode

Tag boots in RAWv1 mode, and modes are cycled by a short button press. Red led blinks on RAWv1 mode and green led blinks on RAWv2 mode.

The data format 5 / RAWv2 has been in use for almost an year and is supported by most community libraries.
Power consumption is calculated at 3 V voltage, and life time is estimated at room temperature with a safety factor of 0.8
