v0.5.7

Added rule to reboot device through JLinkEXE

v0.5.6

• added support for 1 Mbps serial data transfers
• only enable serial port at boot when reset is externally triggered
• force UART to stay powered once serial port is enabled
• avoid printing debug statments if serial port is disabled

Varallo Pombia

Tag firmware

• fixes a few rare issues triggered by high-density situations
• streamlines error handling in the compressed logging routines
• fails gracefully in the rare cases when the compression rate is exceptionally low and the flash log buffer overflows
• robustness against an issue with heatshrink when the encoder overflows the output buffer
• allows to separately specify log block full threshold & compression chunk size at compile time
• gracefully handle failures in flash_log_write() when forcing a flush of the compressed stream
• introduces separate compile-time switches for motion detection and accelerometer-based sleep

Host software

• adds openbeacon-json to dump a JSON stream to stdout (forked from openbeacon-rx)
• adds openbeacon-mqtt to publish received packets as JSON objects to an MQTT broker (using libmosquitto)
• reports reader timestamp, reader ID and packet AES signature in published JSON message
• publishes info on packets with decryption errors to a separate MQTT topic

v0.5.4

• status packet reorganization
• 16-bit status field in status packets
• moving/sleep flags cleanup
• report awaking from sleep
• accelerometer-triggered sleep is disabled by default

v0.5.3

This release adds:

• logging of reason for tag reset
• accelerometer-triggered sleep & wake up (switchable at compile time), for advanced power saving
• minor fixes and improvements

Feral Cat

• Fixes a rare issue with null RSSI in sightings
• boots into awake mode unless flash has been erased

v0.5.1

• Heatshrink compressor tuning
• set a status flag on boot
• minor modifications & cleanup

v0.5.0

This release adds:

• AT45D flash chip library (standard 264-byte page modality)
• proximity logging to flash (switchable at compile time)
• flash log compression using the Heatshrink library (switchable at compile time)
• dumping of flash log to serial port as a base64/uuencoded file
• low-frequency status logging to flash
• tag hibernation maintaining RTC clock
• keypress to hibernate & wake-up tag, to dump flash log to serial, to erase flash
• RTC clock initialization via J-Link programmer and proximity packets
• programmable (at compile time) sequence of proximity TX power levels

It modifies:

• proximity protocol: now we transmit proximity TX power (and no longer transmit protocol byte)
• tracker protocol: now we only transmit epoch time (and no longer transmit angle, voltage, etc.)
• status protocol: packets now contain voltage / accelerometer / flash log / error information
