Changed

• Replace broken compact payload formats (2 and 3) with new version (4 and 5).

Added

• Feedback by LED blinking patterns for success/failure reading data and otaa join.
• Add Reboot Reason and Final Words to status message.
• Add Config Parameter PowerDelay to control warm up time of sensors that are powered by the bridge.

Fixed

• Increase stack size for dialog mode.

1.2.2 - 2020-06-18

Changed

• Using Lobawan 1.2.2 (fixes some issues with OTAA Joins).

1.2.1 - 2020-02-17

Added

• Display Version of Lobaro LoRaWAN Stack on boot.

Fixed

• Fix a crash when using remote command append.

1.2.0

Added

• New config parameter MbAttempts to control how often Modbus Commands will be repeated in case of timeouts.

1.1.1

Changed

• Increased size available for config.

1.1.0

Added

• New optional Listen-Before-Talk Modbus communication, so device can coordinate with another master on bus.

Fixed

• Fix issue that could cut of long Modbus responses.

1.0.3

Changed

• Dialog Mode now logs activity on RS485 Bus while not communicating (to detect other Modbus Masters).
• Log Frequencies for LoRaWAN.

1.0.2

Added

• Wait cycles for optional capacitors to load and stabilize on startup

1.0.1

Changed

• Using FRAM for storing results before uploading, allowing for multiple kB of data to be sent (size depending on hardware).

Fixed

• Removed memory corruption error that could be triggered by configurations with lots of Modbus commands.

1.0.0

Added

• LoRaWAN 1.1 support
• Remote configuration via LoRaWAN on port 128.
• Clock synchronisation via LoRaWAN.

Changed

• Random delay before Uplink (to prevent persistent collisions when using multiple devices).
• Modbus responses longer than payload now get split up (additional parts on port 5).

0.4.1

Fixed

• Changed error indication bit on error 11 from 0xf0 to 0x80.
• Fixed issue when parsing multiple Modbus commands from config.

0.4.0

Added

• Writing values to holding registers and coils.
• Execution of arbitrary Modbus commands triggered by LoRaWAN Downlink messages.
• Support for LoRaWAN Operation Mode Class C (for short reaction time to Downlinks).
• Automated register writing and broadcasts possible through new configuration.

Changed

• Automated reading (triggered by cron) is now configured by entering actual Modbus commands (more flexibility and usage of already existing Modbus syntax – this breaks old configurations).
• Upload format changed to sending raw response to Modbus commands (this breaks existing integrations).

Fixed

• Flushing to avoid invalid byte received from switching from TX to RX.
• Modbus mode ASCII now counts received bytes correctly.
• DataLength of 7 bits can now correctly be set in config again.

0.3.1 - 2019-05-24

Fixed

• Increased robustness of data reception on higher Baud rates.

0.3.0 - 2019-05-15

Added

• Initial release of Firmware for new Hardware revision (with RS485-addon).
• Update Modbus to support all 4 types of registers.

Changed

• Parity bit must not be subtracted from Data bits anymore. 8E1 can now be configured with 8 Data bits, EVEN parity, 1 Stop bit.

0.1.0 – 2018-08-13

Added

• Original hardware release (with RS-485 on holding PCB).
